请各位帮看看这段英文该怎样翻译才比较准确?
我自己试着翻译了一下,不知是否翻译对了?请指点,

《The magnetic nature of disk accretion onto black holes》
Summary
Nature 441, 953-955 (22 June 2006) | doi:10.1038/nature04912;

Although disk accretion onto compact objects—white dwarfs,
neutron stars and black holes—is central to much of high-energy astrophysics,
the mechanisms that enable this process have remained observationally
difficult to determine. Accretion disks must transfer angular momentum in order
for matter to travel radially inward onto the compact object.
Internal viscosity from magnetic processes and disk winds can both
in principle transfer angular momentum, but hitherto we lacked evidence that
either occurs. Here we report that an X-ray-absorbing wind discovered in an
observation of the stellar-mass black hole binary GRO J1655 - 40
must be powered by a magnetic process that can also drive accretion through the disk.
Detailed spectral analysis and modelling of the wind shows that it can only be
powered by pressure generated by magnetic viscosity internal to
the disk or magnetocentrifugal forces. This result demonstrates that disk accretion
onto black holes is a fundamentally magnetic process.

《黑洞周围堆积盘的磁性》
虽然研究致密天体---白矮星、中子星和黑洞---上的堆积盘主要属于高能天文物理学,
但是对此过程的观察仍难以确定其内部结构机理,
堆积盘必须传递角动量以使得物质螺旋进入致密天体,
原则上讲,磁过程的内部粘性和圆盘卷曲都可以传递角动量,
但是至今为止我们难以确定实际情况属于两者中的哪一种,
这里我们发布对双星组成的星际黑洞GRO J1655 - 40观察得到的X射线吸收谱线,
它表明驱使堆积物通过圆盘的一定是磁过程产生的能量,
详细的光谱分析和卷曲模型显示其压缩能量只会是产生于圆盘磁场内部粘性或磁离心力,
这个结果表明黑洞周围的圆盘堆积归根结底是一个磁过程。
