As a consequence, the connection of ABCD theorem with the fundamental " uncertainty principle " in quantum mechanics had been established.

此外应用推广的ABCD定理，可导出推广的含ABCD的衍射积分定理，用角程函的导数来表示。

It is stated systematically in the thesis the methods theories and measuring principle of all kinds of geostress determination technology. In particular the four methods recommended in 1987 by the committee of test method of the International Society of Rock Mechanics, i.e. two over-coring methods of strain relief in boreholes, hydraulic fracturing method and stress furbish measurement which measures the surface stress.

本文较为系统地、全面地介绍了当前国内外通用的各种地应力测量方法的理论、测量原理；特别就国际岩石力学学会试验方法委员会于1987年推荐的4种地应力测定方法(钻孔孔径变形测量法、钻孔孔壁应变测量法、水压致裂法以及测量岩体表面应力的应力恢复测量法)作了较为详细的叙述。

Arms engineering deals with the study of arms and military equipment which are used in military conflict, including technologies of arms launch, ammunition, ballistic trajectory, fusee, fireworks, high-energy materials, flight mechanics, end-point effect and its related arms manufacturing, as well as arms control.

The laws of mechanics are the same in all inertial frames of reference. This is called Galilean relativity

在所有的惯性参照系中，力学定律都是一样的，这叫做伽利略相对性。

In soil mechanics theory, the soils are regarded as continua as a rule after the substance morphology is fallen into gaseity, liquid and solid. Now the continuum theory is used in most of numerical methods.

尽管连续介质的假设与实际情况不相符合，目前大多的数值计算方法都是用连续介质力学的思路去分析和研究土的力学性状。

Even after powerful work of the mechanistic scientists like Gassendi the change was not easily completed: Isaac Newton, whose name is associated more than any other with physical mechanics, dabbled frequently in alchemy.

即使在像Gassendi这样的机械论科学家发表有力的论文之后，变化仍然没能轻易完成：牛顿·艾萨克，他的名字与机械力学的联系比其他任何人都密切，也频频尝试炼金术。

Then the momentum P in the acquired motion equation is replaced by quantum operator, thus we obtain Schrodinger equation for charged particle moving in magnetic fields in Quantum Mechanics. Then we discuss the Gauge transformation and gauge invariance of Schrodinger equation, following which the Dirac phase is introduced.

然后把经典力学中的哈密顿量量子化，得到量子化的带电粒子在磁场中运动的薛定谔方程，之后是薛定谔方程的规范变换和规范不变性，并引入Dirac不可积相因子的概念。

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.
