守恒

For conservation of momentum, the atom must recoil with a momentum of this magnitude in the opposite direction.

因为动量守恒，原子必然以这样大小的动量向相反方向反冲。

40In this chapter we develop the implications of momentum conservation in the motion of a collection of particles.

本章将揭示群质点运动时动量守恒的含义。

On the basis of momentum conservation this paper focuses on the study of flow mechanism of the header and its flow static pressure distribution.

The equation of conservation of momentum is changed into a quadratic equation of a certain physical quantity.

将动量守恒方程变成一个物理变量的二次方程。

Based on momentum balance and the law of momentum conservation, two new graphic methods are developed to determine the pre-impact vehicle momentum or collision speed in this paper.

本文根据动量平衡和动量守恒定律的基本原理，提出了两种推算碰撞前汽车动量或碰撞速度的图解方法。

第3周 动量定理动量守恒定律及应用；变力的功、保守力的功、势能。

This internal linkage raises a conservative force within the genome that pushes on itself to keep the genome unchanged -- regardless of what body it makes.

这种内在的结合在基因组内培养了一种守恒力，并强加于其自身以保证基因组不变化——不管它制造的是何种躯体。

The latter also includes material wealth, which is not conserved, and thus may have a different e.

后者也 包括物质财富，这是不守恒，因此可能有不同的分布。

Energy is conserved, that is, none is lost and none is increased.

能量是守恒的，也就是说不会减少，也不会增加。

The idea that energy is conserved is the first law of thermodynamics.

能量守恒这一概念是热力学的第一定律。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
