有求会英语的网友： 我不会英语，却想为二十年前的一篇文章找个出路，希望能给世人留下一点思考。十月中旬我去北京找翻译公司，有几家被我执着的追求打动，愿为我译出文章的摘要供我选择。现在译出的摘要已发给我，但我的会英语的亲戚看后认为自己难以把握（学经济的）。因此，在这儿求助网友帮忙，鉴别哪家的翻译保持着摘要的原意、不走样。谢谢！ 以下是译文： 不连续的波——《弹性动力学》 摘要：基于《弹性动力学》存在着一系列的问题，笔者认识到这个理论创建于对弹性质元使用牛顿第二定律之上违背质点概念，是该理论的根本性错误，也就有了建立一个新理论的愿望。而促成这一愿望实现的却是我们常说的一句话："通过现象看本质"。在这句话的启发下研究了《弹性动力学》中的平面波，从中发现了粒子性，领悟在平面波中寻求遵从力学规律的粒子就是解决弹性波问题的关键。正是坚持了这一目标的寻求，又从平面简谐波中找到了具有力学独立性的粒子--波质元，使弹性波遵从的力学规律得到了展现，从机制上解决了弹性波的反射与折射、传播、激发三大问题，证明了弹性波是由波质元间弹性碰撞产生的惯性波，否定了《弹性动力学》给出的应力波，形成了一个基本功能齐全、无假设、波具有不连续特征的《弹性波的粒子理论》。但鉴于《弹性动力学》在探索未知中能突破道理成功地获得了一些与实验吻合或近似吻合的现象、在实践中取得的巨大成就、为建立《弹性波的粒子理论》提供了基础，这一件件都是人类所需的成果、所犯错误的功绩。因此，《弹性动力学》必是开拓未知世界获取现象的方法，应作为我们认识未知世界不可或缺的经验存在物理学中。两个学说的关系提醒我们：自然界的本质规律潜含在现象之中，由现象规律确定，按理揭示本质规律的理论必须建立在已知的现象规律之上。 1号翻译公司： Abstract: Based on some issues in "Elastodynamics", the author recognizes that this theory is proposed based on the elastic mass element using the Newton Second Law and violates the mass point concept, which is a fundamental error in this theory, so I expect to establish a new theory. This wish is realized via one popular word "observe essence via phenomena". Inspired by this word, I study the plane wave in "Elastodynamics", find the corpuscular property, and understand that the key is to find the particles obeying the dynamics law from the plane wave. Depending on my pursuit for this target, I find the wave mass element from the plane simple harmonic wave, one particle with dynamical independence, which makes the elastic wave obey the dynamics law, solves reflection, refraction, propagation and excitation of the elastic wave from the mechanism, proves that the elastic wave is the inertial wave generated due to elastic collision between wave mass elements, denies the stress wave in "Elastodynamics", and forms "Elastic wave particle theory" with complete basic functions, no assumption and discontinuous wave. "Elastodynamics" breaks through the law, successfully gets some phenomena matching with or approaching to the experimental results, has achieved some great achievements in practice, and provides foundation for "Elastic Wave Particle Theory" in exploration of unknown fields. All findings are the achievements required by human being and are based on the made mistakes, so "Elastodynamics" will become the method to explore unknown world and get phenomena and should be included in the physics as our necessary experiences to know the unknown world. The relation between two theories reminds us that the essential law of the nature is potentially included in the phenomena and is determined by the phenomena law. The theory reflecting the essential law should be based on the known phenomena law. 2号翻译公司： Abstract: Based on a series of problems in Elastic Dynamics, the author realized that this theory was established on a basis of Newton's Second Law used for elastic material element, which was against the concept of material point, leading to the fundamental error, and thus the auther has a desire to set up a new theory. A saying "to see the essence through the phenomenon" promotes the realization of this wish. Inspired by this saying, the plane wave in Elastic Dynamics has been studied to find the particles, and understand that seeking the particles following the law of mechanics in the plane wave is the key to solve the problem of elastic wave. Sticking to the seeking of this goal with the discovery of the particle with mechanical independence, i.e., wave material element in the planar simple harmonic wave (contanining the elastic material element of wave velocity), the mechanic law followed by elastic wave is displayed, which solves the reflection, refraction, propagation and excitation of elastic wave from the mechanism. It is proven that elastic wave is the inertia wave produced by elastic collision between wave material elements, denying the stress wave given by Elastic Dynamics. As a result, Particle Theory of Elastic Wave is formed with basically complete functions, no assumptions and discontinuous characteristics of waves. Elastic Dynamics can make breakthroughs to successfully gain some phenomena consistent or similarly consistent with the experiments, obtain remarkable achievements in practice and provide the foundation for the Particle Theory of Elastic Wave. These are the achievements for human from mistakes. Therefore, Elastic Dynamics is the method to exploit the unknown field and understand the phenomena, which should be indispensable experience in physics to recognize the unknown field. The relation between the two theories reminds that the essential law of the nature is hidden in the phenomenon, which is determined by the phenomenon law, and the theory to reaveal essential law must be based on the known phenomenon law. Keywords: physical model of elastic medium, wave material element, momentum theorem, function theory, Newton's Third Law, conservation law of momentum and energy, total boundary 3号翻译公司仅翻译了摘要一段，还有一句不理解的话： Abstract: Based on a series of problems in "Elastic Dynamics", (笔者认识到这个理论创建于对弹性质元使用牛顿第二定律之上违背质点概念====这句话，中文我都捋不顺) is the fundamental error of the theory, therefore, I also have a desire to establish a new theory.
