查询词典 mechanics

In the modified Newtonian mechanics, the law of conservation of momentum and the law of conservation of energy become invalid; instead, the inherent momentum and inherent kinetic energy can be defined to make the law of conservation of inherent momentum and the law of particle inherent kinetic energy valid.

在修改后的牛顿力学中，动量守恒定律和能量守恒定律不再成立，但可以定义固有动量和固有动能，使得质点系固有动量守恒定律和质点固有动能守恒定律成立。

Here is a different state of affairs from classical mechanics, where absolute uniform motion is quite meaningless because of Galileo's law of inertia.

这里的情况跟经典力学不同，在经典力学中，由于伽利略惯性定理的关系，绝对的匀速直线运动是毫无意义的。

Classical mechanics, but Galileo, the creator of "the embryo form of law of inertia",with the incline experiment only attested to the falsity of Aristotle's proposition that "the force is the indispensable factor to maintain object movement", and not proposed what is the indispensable factor to maintain object movement.

牛顿第一定律被认为是经典力学的最基本定律之一，但"惯性定律雏型"的原创者伽利略用斜面实验只证伪亚里士多德的"力是维持物体运动不可缺少的因素"这一命题，并没有提出什么才是维持物体运动不可缺少的因素。

The branch of mechanics based on Newton's laws of motion .

基于牛顿运动定律的力学分支。

The study of the mechanics of fluids or the laws of equilibrium and motion concerning fluids.

这种踏板车运用的是卡门曾在轮椅那项发明上应用过的"动态平衡"技术。

I think they were legitimately talking about the mechanics too, not the fact that they could roll anyone.

我相信他们在做客观的评价，而非因为他们可以横扫千军。

The whole drillstring is taken as research object in this paper. Mechanics model for lengthwise vibration analysis of deep well drillstring is established.

本文以整体钻柱为研究对象，建立了深井钻柱纵向振动分析的力学模型。

Mechanics model for lengthwise vibration analysis of deep well drillstring is established.

本文以整体钻柱为研究对象，建立了深井钻柱纵向振动分析的力学模型。

In terms of continuum mechanics and nonequilibrium irreversible thermodynamics theories, compressible Leonov constitutive model is derived to describe large recoverable elastic strain development in non-isothermal flow of compressible viscoelastic melts. It is tempting to specify the model and then compare it to basic rheological tests in the hope that such a model will yield a good description of the nonlinear viscoelasticity of polymer melts.

注射成型是聚合物的主要成型加工方法之一，成型过程中聚合物要经历熔体流动和固化等非等温、非平衡过程，由于聚合物的粘弹性，流动过程中建立的剪切应力、法向应力和大弹性形变在固化过程中不能完全松弛，在制品中形成残余应力和取向，对制品的机械和光学性能有着重要影响。

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.

交际能力和语法的关系应该是目标与途径的关系。
