在所有作相对运动的惯性系中都可以应用同样的力学定律。

The problems were designed not only to get them a working knowledge of the mechanics of combat but to teach the most basic thing an infantryman has to know: how to love the ground, how to use it to advantage, haw the terrain dictates tactics, above all how to live on it and in it for days at a time without impairment of physical efficiency.

所设计的问题不仅给他们一些战斗机制运作方面的知识，而且教会他们步兵必须了解的基本知识：如何判读地形，如何利用有利地形，如何根据地形采取不同战术，尤其是如何在地面生存，在不影响体能的情况下一次在地面生存好几天。

The classical mechanics of materials is based upon the linear elasticity, infinitesimal deformation, and isotropic hypotheses, which has big constraints.

传统的材料力学教材基于线弹性、小变形、各项同性等基本假设，不可避免地具有很大的局限性。

This has just reached ouraim of establishing a quantum theory of potential scattering inphase space in the sense of the pure quantum mechanics.

这恰好就达到了我们在纯量子力学意义上建立相空间势散射理论的目的。

The LDV instrument for instantaneous velocity measurement is developed which connected with the technology of optics, mechanics, electronics and computers designed.

In this paper, an important integral relation in terms of convolutions is given, which can be considered as the generalized principle of virtual work in mechanics.

文中首先给出一个重要的以卷积表示的积分关系式，可以认为，在力学上它是一个广义虚功原理的表式。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
