作为特例，当粘弹性指标分别为α=0和α=1时，以上方程组即为经典的弹性力学和牛顿流体力学基本方程。

The concept of adiabatic approximation and adiabatic invariant came from research on obit deformation in classical mechanics.

然而一直以来，物理学界对QAT的适用性问题上都存在一些模糊的认识。

Since the structure and the shape of the crankshaft are complicated and the loads vary periodically,it is difficult to calculate its strength and rigidness using classical mechanics.

因为曲轴的结构形状比较复杂，各个曲拐的受力又在发生周期性的变化，所以运用经典力学对其进行强度和刚度计算有一定的困难。

Why do Maxwell's equations differ in form and character from the equations of classical mechanics?

麦克斯韦方程何以在形式上和性质上都跟经典力学中的方程不同呢？

In classical mechanics, velocities are directly additive and subtractive.

Fully considered the structure and process characteristics of strip mill shape detection equipment,through plenty of field experiments and theory study,a set of error analysis model fit for strip mill shape detection equipment has been set up for the first time with combining theory of the classical mechanics and modern computer technology,which will create the right complex error compensation scheme and put it into the productive practice.

充分考虑板带轧机板形检测设备的结构与工艺特点，经过大量的现场试验与理论研究，将经典力学理论与现代计算技术有机结合，首次建立了一套适合于板带轧机板形检测设备系统误差分析模型，给出了相应的误差综合补偿方案，并将其应用到生产实践，对不同张力下检测辊的挠曲、倾斜、磨损等因素进行了综合补偿，大大降低了现场的板形封锁率，给企业取得了较大的经济效益，具有进一步推广应用的价值。

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。
