回复:想听听您对我观点的总体评价
1)推导相对论多普勒效应,有许多方法,每种方法或要用到速度合成公式或隐含了速度合成公式;
2)对于声速,严格的正确的速度合成公式既不是C+V(C为声速),也不是(C+V)/(1+CV/C*2),而是更为复杂的形式,因为(U+V)/(1+UV/C*2)只适用于粒子(或者说具有粒子性质的物质波,包括光子),但不适用于声波、水波、绳子波等,因为这些波都与介质运动有关。为了得到声速的速度合成公式,需要分析空气分子运动的坐标变换,还涉及到温度的LORENTZ变换(热力学的相对论变换现在一直没有解决,是个世纪难题,汤川秀树的书中专门有一章讨论这个问题),总之,声速的相对论变换是很复杂的问题,可以认为国际上还没有人解决这个问题。所以,绝对不能说只要变动一个字(把“光”变为“声”),就可以照办相对论用到声速问题上去。绝对不是怎么一回事。
3)HUDEMIN,我也不大愿意讨论过分细节的东西,只讨论大的问题。不过,我指出一下,您的7。14日21:09帖子中的关于对相对论矛盾的质疑问题中,有许多是您自己造成的问题。比如,您说:“小小光子,竟然能量可以无穷,不可思议”,从而认为相对论不妥。其实,咖马光子的能量(MeV)都比电子重。在早期宇宙中,都是光子劈裂为重的物质粒子的。在用接近光速的星际航行中,飞船碰上一个光子(还有原子),都可能使得飞船瓦解。这些问题(虽然我们还没实验过)也都是宇航学家对星际航行持悲观态度的原因。在高能物理实验中,上百GeV能量的正反电子湮灭,生成的光子能量比100个质子静止能量还大。
我现在还没有拿到您的书,再过几天,我就好好研究您的书。我会把反馈意见寄给您的。

回复:想听听您对我观点的总体评价
沈先生,您好!

1.您说“推导相对论多普勒效应,每种方法都要用到速度合成公式或隐含了速度合成公式”,这一点没有错,但你说(U+V)/(1+UV/C*2)不适用于声波,恐怕就不对了。因为我所主管的武器装备项目正好与水声学有联系,对此问题,我多少还知道一些。需要注意的是,现在我们所讨论的是由相对运动引起的速度合成,而不是讨论声波在水(或空气)中的传播速度变化情况,两者含义是不同的。声波在介质中的传播速度(确实正如您所说的)与介质性质有关,甚至还与温度梯度、盐分等有关系,但这些都与我们讨论的问题无关。我们所讨论的是,当观察者运动(而声的传播速度固定不变)时,观察者观察到的声速是多少,这自然是(U+V)/(1+UV/C*2)了。确实,声波和光波不能完全作简单类比,因为声波还有介质的存在,而光波没有(或者如您所说的真空介质),但单纯在我们所说的推导多普勒效应方面,还是能类比的。
2.您说我指出的相对论的矛盾,有许多是我自己造成的,我不太认同。这涉及到如何看待矛盾,以及以何种态度来看待矛盾了。同样一个问题,有些人看起来有矛盾,有些人看起来没矛盾。比如,“双生子佯谬”问题,在反对相对论的人的眼中,问题多多,但在支持相对论的人的眼中,却没有什么问题。我说“小小光子,竟然能量可以无穷,不可思议”,意思是说虽不足以用它来否定相对论,但总让人觉得牵强。不过,一个理论,如果有许多地方让人觉得牵强,其正确性就不得不令人怀疑了。您还没有看过我写的书,还没有理解我的全部想法,有些地方您不同意,这很正常。等您看了我的书,您的看法也许会改变许多,现在不觉得有问题的东西,到时您可能也会感到有问题。
3.至于您所说的有些光子的能量比电子还大,我不否认这样的光子的存在。但我说的是,如果原本就是一个质量非常小的普通光子,能仅仅因为观察者自身的运动接近光速而感觉其能量无穷大吗?这与是否有巨大质量的光子存在是两码事。
希望您拿到我的书后先好好审视一下我的思路,然后再谈具体问题。对相对论讨论过的问题,我自认为都给出了更为清楚、明了、合理的解释。

如果你真的准备谈具体问题,我们还可以继续讨论


你能回贴,说明你这个人度量还是有的,这一点还不错。如果你能放弃你现在这种讨论问题的方法,进行“具体问题式”的讨论,我仍然可以与你交流。
说实在的,我这个人最注重实验(这有可能与我是学工科的有关),对相对论的书籍,我看的最多的是实验,我写书最重要的一本参考文献就是张元仲所著的《狭义相对论实验基础》,对于我所提出的假设,我尤其注重用以前人们做过的实验去检验,我不知因此推翻过多少种假设。我现在提出的假设,都能用已有的实验去检验。与大多数人不同,对我提出的新的光速假说——光介子假说,我还专门设计了一个判决性实验方案,我期待有人做实验对我的假设作出判决。怎么说我不注重实验呢?怎么说我“连一个实验支持也没有就出书立说”呢?告诉你,评价一个人要慎重。你多次说别人不懂这个、不懂那个,似乎别人都不配谈物理,这样,你能把你自认为最耀眼的东西拿出来让大家瞧瞧吗?是博士、博士后,抑或是博导、院士?

内容: 上网收信,所以顺便来看看,并作一一答复。
Hi,你好,兔子王。首先我谢谢你的参与。
我想谈几个我的观点。
第一,对相对论中光速的不可超越性的置疑(当然,不是对相对论的置疑。相对论中此部分只是少了一个小小的限制条件,无大碍):光速真的是运动速度的极限?不,不是的。美国普林斯顿大学的科学家王利军、亚历山大·库兹米奇和阿瑟·道格鲁最新的研究成果,首次证明了世界上有比光速还快的东西!的确,光子不就是以光速运动的吗?只要对以光速运动的光子(或电子)施力,要超越光速不是不可能的事,困难的只是技术问题。现在实验已经证明了这一切。也许你要说,这不是和爱因斯坦的相对论产生了本质上的矛盾吗?
第二,对光速的不可改变性的肯定:大家知道,如果在以声速飞行的喷气式飞机上发射一颗导弹,他相对于飞机的速度也是声速,那么,在地面上的人看来,这颗导弹将以两倍于声速的速度向前飞行。这是根据经典物理学速度合成公式得出的结论,也是经验证的无可置疑的事实。但是,如果在以光速飞行的火箭上发射一束光,那么,这束光对于地面上的观察者来说,是否会以两倍的光速向前传播?回答是否定的。因为光速是不可改变的!(这是相对论的基础,是经实验验证了的)所以对于光速火箭来说,火箭上发射的光束是静止的,对于地面上的观察者来说也就是以光速传播而已。(但换一种方法,在以光速飞行的火箭上发射一颗声速导弹,那么,这颗导弹不就超越光速了么?)
第三,对时间的不可逆流性的坚持:实验证实,在高速状态下运动的物体将发生长度变短、时间变慢、质量加重之类的一系列相对论效应。既然,光速可以超越,那么,是否时间会随速度提高慢至停止,最终导致倒流?我的回答是否定的。速度不为负,所以速度与时间的关系可以用反比例函数 t=k/v(t为正) 来表示。实验证明,K取值的设想是成立的。即v越大,t越小;但即使v取无限大,t也只能是无限接近v轴,不可能为零更不可能为负!所以,超越了光速,可以看见过去的光线,但是却不能使人置身历史之中(或许还会造成混乱现象,是个科幻素材)。而且,以光速甚至更高的速度运动的物体,由于一系列的相对论效应,基本微粒之间的引力一般无法保持分子状态,而是分解了以波的形式存在。
所以,超光速的运用只能限于研制超速电脑等信息领域上。要想人类进行超光速旅行,等人类进化成四维思维体再说吧!
(另外,我认为所谓的单纯的“1+1=2”的证明是没有意义的,他只是人们用于帮助交流的一种工具,是一种人为的规定,逻辑上就是“约定俗成”吧?当然,可别把哥德巴赫猜想“1+1=2”和这里的东东混起来了!!!:)至于人的思维嘛~~~~~~大概可以理解为无数微粒的集合产生的集体链式反应?不是已经有类似的文章在《科幻世界》发表过吗?P.S.你是兔子党的吗?)
winner兄,你何必要用这些东西来问我呢?翻翻有关的书籍吧,会有满意的答复的。P.S.我可不是那种用《百科全书》在网上充胖子的人。。。
引用君子好逑的一句话:“原来全是些搬书虫。”外星酷哥先生,我点了你的名让你来,是为了了解你。你已经不用再帖了。现在我的目的达到了。你真的让人失望。我想看到的是你个人的真知灼见。或许我当初的选择就不对。。。。算了,不提了。
Red marse你好,第1题本身就是一道估算题,要求你要对客观事物有一定的了解。(我是说数据应该由你自己推测,试试看。你一定能行的!)
好了,看来是把上面的能回复的都说了。明天见吧:)

惯性质量与引力质量(一种供讨论的观点)
惯性质量与引力质量
沈建其
浙江近代物理中心及浙江大学物理系,杭州 310027
摘 要 本文对匀强引力场中光子运动的研究证明了广义相对论的基本假设之一等效原理是Lorentz不变性的结果。对于惯性质量与引力质量的相等性也作了讨论。
关键词 惯性质量 引力质量 等效原理
在相对论的发展史上,作为广义相对论的基本假设之一的等效原理起了重要作用。等效原理有两方面互为相关的内容:①引力质量与惯性质量等效;②引力场与加速场等效。历史上许多研究者曾用实验检验等效原理。惯性质量与引力质量等效的意义是:引力质量与惯性质量成正比或绝对相等。由此,这些实验工作包括:①证明引力质量与惯性质量成正比,且常系数与物质具体特性无关;②证明引力质量与惯性质量相等。由于等效原理是广义相对论的基本假设之一,它应该无法由第一性原理证明。但是本文认为惯性质量与引力质量的等效是Lorentz不变性的结果。因此等效原理作为一条独立的基本原理的地位受到了挑战。下面通过研究在匀强引力场中运动的光子来证明这一点。
1、牛顿第二定律的相对论修正:
设作用在物体上的力为 ,则加速度 为
(1)
其中 为物体静止质量。推导过程略。
2、设一个升降机在匀强引力场(场强为 )中作自由落体运动,地上的观测者测到的升降机速度为
(2)
其中 为光速,时间 属地面观测者的时间。由(1)式可导出(2)式。由(2)式看出,当 时, ,也即光速不能逾越。
3、假设升降机内存在一个光子,且沿与场强 同方向运动,频率为 。由于光的Doppler效应,显然 是依赖于时间 的。但在升降机内的观测者看来,他处于一个惯性系中,因而光子频率不变,设为 。 与 有下面的关系
(3)
代(2)式入(3)式,得
(4)
4、在地面上的观测者看来,光子在引力场中运动,存在着引力势能与光子动能的相互转化,引力做微功
(5)
根据相对论动力学, 则上式化为
(6)
积分,得
(7)
比较(4)式与(7)式,得
(8)
根据德布罗意关系 ,得

或

从而最终有
(9)
从而得到
, (10)
其中 是一个常系数,与物质具体特性无关。
由于局域的Riemann空间是一个局域惯性系,作自由落体运动的电梯内也是一个惯性系,所以上面的推论只用到了狭义相对论的结论。引力质量与惯性质量的等效是狭义相对论Lorentz不变性的结果。下面需要关心的问题是常系数k所具有的物理意义。关于检测引力质量与惯性质量是否相等的实验一直有人在做,如今已精确到10-12的量级以上(Braginsky,1972),看来k=1也许是可以肯定的了。但是如何从理论上证明这一点呢?有人会说这好办,只要把它吸收进引力常数中去,从而得到mgra=mine。我认为这种技巧是错误的。我们不能通过重新定义引力常数解决问题,因为在弱场近似下,引力场强和物体加速度都是客观确定的,原则上由它们的测量可以定出k值。通常自卡文迪许以来用实验测定的引力常数实际上是Gk2的值(G是真正的引力常数),这样我们是可以完全定出G的。在广义相对论框架中可以回答 问题。不再详叙,只以一个简单的推导说明之。以施瓦西外部场为例,为了计算的方便,令其中角坐标 ,则惯性质量为
的单粒子的作用量为 (10)
那么拉格朗日量为
(11)
它是平直空间作用量 在弯曲空间的推广。由拉格朗日动力学,与正则坐标 共轭的正则动量 为 ,则哈密顿量为
(12)
在弱场近似下,它退化为物理意义十分明显的三项
(13)
上式右边第三项就是弱场近似下的引力势能。
根据牛顿引力理论,引力势能为
(14)
比较式(13)与(14),得到
(15)

粒子自旋---引力耦合理论
On the Spin-Rotation Coupling and an Application to the Rotation of Earth
JianQi Shen1, 2 HongYi Zhu1, 2 ShenLei Shi2
(1.State Key Laboratory of Modern Optical Instrumentation, HangZhou, 310027; 2. ZheJiang Institute of Modern Physics and Physical Department of ZheJiang University, HangZhou, 310027)

ABSTRACT:
The Kerr metric of spherically symmetric gravitational field is analyzed by considering the coordinate transformation from the rotating system to the fixing system, and consequently that the inertial field (with the exception of the centrifugal force field) of the rotating system is one part of its gravitomagnetic field is verified. We investigate the spin-rotation coupling and the geometric phase factor in the time-dependent gravitomagnetic field. A possible application of this geometric phase factor to the investigation of the fluctuation of the angular velocity of Earth’s rotation is also discussed in this present paper.
Keywords:
spin-rotation coupling, gravitomagnetic field, invariant theory, geometric phase factor


It is easily verified that the form of the weak field approximation of the equation of the gravitational field is in analogy with Maxwell’s equation of electromagnetic field. It is the most outstanding point that the former also possesses both the gravitoelectric potential written as and the gravitomagnetic potential as , and the corresponding gravitomagnetic field strength is of the form . A particle with intrinsic spin possesses the gravitomagnetic moment of such magnitude that it equals the spin of the particle. Thus the interaction between the gravitomagnetic moment and the gravitomagnetic field is also called the coupling of the spin with the gravitomagnetic field, of which the Hamiltonian is given by
. (1)
The strongest gravitomagnetic field, which we can find on the Earth, is the one caused by the rotation of the Earth. Since the Earth is a noninertial reference frame due to its rotation, the particle with spin is coupled to a more strong gravitomagnetic field which embodies the interaction between the spin and the noninertial frame in addition to the interaction expressed by Eq.(1). It is apparently seen that the spin-noninertial frame interaction is in connection with the Coriolis force. These two gravitomagnetic fields have different origins and properties. The gravitomagnetic field from the motion of material, expressed by , is analogous to the way the electric current leads to the magnetic field. And its strength is dependent on the Newton’s gravitational constant G. The gravitomagnetic field associated with the Coriolis force is caused by the choice of the coordinate. That is, the coordinate transformation from the rotating frame to the fixing frame results in the inertial force, observed by the observer fixed in the rotating frame in accordance with Newton’s Law.
Obviously, the latter magnetic field is independent of the Newton’s gravitational constant G. Due to the smallness of G, the coupling of the latter gravitomagnetic field with spin is stronger than that of Eq. (1). In the present paper, the interaction between this inertial force field and spin is just investigated. According to the equivalence principle, the inertial force is gravitational force by nature. Consequently, these two gravitomagnetic forces can be derived from the equation of gravitational field, which has been proved in Sec.1. Thus we obtain the Hamiltonian of the coupling of spin-rotation. It is known that Mashhoon’s approach to deriving the intrinsic spin-rotation coupling is given by analyzing the Doppler’s effect of the rotating frame with respect to the fixing frame. In this paper, however, the transformation of the gravitomagnetic potential is studied through the coordinate transformation, the Hmiltonian of the interaction between the intrinsic spin and the noninertial frame thus obtained.
The reason why the coupling of the spin (or gravitomagnetic moment) with the noninertial frame and the gravitomagnetic field is of great importance, is that the development of laser technology and applications of the precise instrumentation make possible the investigation of quantum mechanics in weak-gravitation field. The use of these weak effects of the relativistic quantum gravity enables people to test the basic principles of general relativity. Although the equivalence principle is still accurate, there are some interesting phenomena, such as the violation of Galileo’s principle of free falling body for the particle with spin in the Kerr space-time.
Since the analogy can be drawn between the gravity and electromagnetism in some aspects, Aharonov, Carmi and Anandan, Dresden, Sakurai et al. proposed the geometric effect of the vector potential of inertial force and the effect of the quantum interfere associated with gravity, respectively.
On the rotating reference frame, a particle was acted on by the inertial centrifugal force and Coriolis force, which are analogous to the electric force and magnetic force. Thus the matter wave on the rotating frame will possess an integral phase factor which has been called Aharonov-Carmi (A-C) effect, or the gravitational A-B effect. Overhauser and Colella, Werner, Standenmann et al. have proved the existence of A-C effect by making use of the neutron interferometry experiment. In fact, A-C effect is due to the interaction of the momentum and the noninertial frame. Although the spin of a particle such as neutron interacting with the noninertial frame has the same origin of the A-C effect, namely, both arise from the presence of the Coriolis force, the A-C effect mentioned above doesn’t contain the spin-rotation interaction. Berry’s theory of the gemometric phase proposed in 1984 is applicable only to the case of adiabatic approximation. In 1991, on the basis of the Lerris-Riesenfeld(L-R), invariant theory X、C、Gao et al. put forward to th invariant-related unitary transformation formulation which is appropriate to treat the cases of non-adiabatic and non-cyclic process. Hence, L-R theory developed into this generalized invariant theory which is a powerful tool to investigate the geometric phase factor. In Sec. 2 the spin-rotation coupling is taken into consideration by using this method.

1. the interaction between spin and gravitomagnetic field
The Kerr Metric of the exterior gravitational field of the rotating spherically symmetric body is of the form
(2)
where are the displacement of spherical coordinate; denotes the angular momentum of unit mass and possesses the dimension of length. Since the space-time coordinate of Kerr metric (2) is on the rotating reference frame, we transform it into that the fixing reference frame. Due to the smallness of Earth’s rotating velocity, , one can use the Galileo transformation
, (3)
with being the radial velocity, the space-time coordinate of the fixing frame, the space-time coordinate of the rotating frame, then . Substitution of Eq. (3) into the expression (2) leads to
(4) where in leads to the inertial centrifugal force . Neglecting the terms corresponding to in , we can obtain
, (5)
thus the gravitomagnetic potential can be written as
. (6)
It can be easily seen that, , the first term of , is closely analogous to the , which corresponds to the magnetic potential of the rotating charged spherical shell. Then we can calculate the exterior gravitomagnetic strength of the Kerr space-time and the result is with being the angular momentum of unit mass of the rotating spherical body.
In accordance with the form of post-Newtonian approximation of the equation of the geodesic equation, the gravitomagnetic strength can be defined by with . Set , then the gravitomagnetic strength, which arises from the choice of the reference frame, is
, (7)
which is related to the rotation and a part of the gravitomagnetic field. From the point of view of Newtonian mechanics, it is the innertial force field in essence, not resulted from the mass-current denisty. Since we have assumed that the velocity of a particle is parallel to namely, the Lorentz force acted on the particle in the gravitomagnetic force is given by
, (8)
hence, we conclude that the Lorentz force in the noninertial reference frame is the well-known Coriolis force. The gravitational field is in analoy with the electromagnetic field, by reason of the analogous forms of the gravitational field equation of post-Newtonian approximation and the Maxwell electromagnetic equation. Then, the interaction Hamiltonian of the coupling of a spinning particle with the gravitomagnetic field is of the form
, (9)
The two parts of the gravitomagnetic field have different origins: the former, , arises from the motion of mass and is in connection with the gravitational constant G; the latter, , originated in the transformation of coordinate from the rotating frame into the fixing frame. And it is independent of the gravitational constant G. The latter is stronger than the former by 1020 times for the Earth, thus, is neglected and (9) is rewritten as
, (11)
For the neutron, then we have
. (12)

2. The exact solution of the time-dependent Schrdinger equation describing the spin-rotation coupling of the neutron

The variation of the Earth’s rotating angular velocity may be caused by the motion of interior matter, tidal force, “YangLiu”, atmosphere etc. Once we obtain the information on the fluctuation of the rotating velocity of the Earth, it is possible to investigate the motion of matter on the Earth. For the sake of detecting the fluctuation of the rotating velocity, we propose an approach to measure the geometric phase factor arising from the interaction of neutron spin with the Earth’s rotation, by making use of the neutron – gravity interferometry experiment. The time-dependent Schrdinger equation which describes the neutron spin-rotation coupling is as follows:
, (13)
Set , and , then the expression (12) can be written as
. (14)
According to L-R invariant theory, an invariant is easily constructed which satisfies the following invariant equation
. (15)
Since the Set forms a complete algebra, and the is the linear combiation of this algebraic generator, the invariant is surely of the form
. (16)
Where the time-dependent parameters and satisfy two auxiliary equations
, (17)
which are obtained by inserting (14) and (16) into Eq.(15). In Eq.(17), the dot denotes the time derivative.
According to the L-R invariant theory, the particular solution of the time-dependent Schrdinger equation differs from the eigenstate of the invariant only by a time-dependent phase factor which is expressed as , where
, (18)
Thus the particular solution of the time-dependent Schrdinger is given by
. (19)
In order to obtain the eigenstate of the invariant and the expression for the phase, we transform the time-dependent invariant into a time-independent invariant , namely,
, (20)
Where
, . (21)by using the invariant – related unitary transformation formulation.
Complicated and lengthy calculation yields
, , (22)
then , which may be written as
. (23)
is time-independent.
Since the eigenstates of corresponding to the eigenvalue are and respectively, the particular solution of the Schrdinger equation (13) can be written as
, (24)
and
(25)
where the phase comprise the dynamical phase and geometric phase which are defined as
. (26)
Using the Baber-Campbell-Hausdortt formulation, we get the expression
, (27)
for the dynamical phase and
. (28)
for the geometric phase in the neutron spin-rotation couplings.
From (24)-(28) we obtain the exact solutions of the time-dependent Schrdinger equation (13). It can be further verified that in the expression (27) vanishes in terms of the auxiliary equation (17). Hence, the solutions of Eq.(13) contain only the geometric phase. Since the geometric phase factor possesses the physical meanings, it can be measured in the neutron-gravity interferometry experiment. The signs of the geometric phase of the neutron corresponding to the spin-up and spin-down are opposite and thus this effect due to the spin- rotation coupling will be detected by the neutron interferometer. Once the time-dependent expression for the geometric phase, is obtained, we can investigated the fluctuation of the Earth’s rotating angular velocity in terms of the auxiliary equations(17) and Eq.(18).

CCDXL,等效原理的成立有其条件
荡秋千、乘电梯、刹车等情况由于身体内部受到挤压,所以当然能把引力场与加速场区分开来。为什么会如此,因为对于这种刹车和电梯刚开始加速的突发性情形,力在身体里的传递需要时间(比如,电梯刚加速时,头顶与脚底的瞬时加速度就不一样,导致身体感到挤压。当然这个时间极短),这就是我所说的“惯性力分布不均”。等效原理当然不成立。
等效原理的成立是有条件的。
广义相对论本身也证明加速场不能完全抵消引力。如,计算黎曼曲率张量(它是判断时空弯曲是否的判据),就会发现即使将运动方程变换为局域惯性曲率张量仍旧不为零。这说明等效原理并不真正等效。
同样,引力质量与惯性质量在运动理论(爱因斯坦等,40年代发展)也有区别,两者并不相等。
