动量守恒

This is the well-known principle of conservation of momentum.

这就是众所周知的动量守恒定律。

In this chapter we develop the implication's of momentum conservation in the motion of a collection of particles.

在本章中，我们要揭示一个质点集体作运动时动量守恒的含义。

Based development of physics history,We explain the development of momentum conservation in the physics and it is universality in nature.

本文根据物理学的发展历史，说明了动量守恒概念的发展及其在自然界中的普适性。

This is called the 1aw of conservation of momentum .

这称为动量守恒定律。

The principle of conservation of momentum holds whatever the nature of the internal forces, conservative or not.

动量守恒原理则不管内力的性质如何都能适用。

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.

本文在动量守恒的基础上，研究汇流集箱的流动机理和集箱流体静压分析，锅炉汇流集箱流动的基本规律和设计参数。

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。

On the basis of Navier-Stoks equation and continuity equation, the SOLA-VOF method was adapted to calculate the field of velocity and pressure in fluid in this program. According to the inertia and continuity of fluid, a new velocity boundary conditions of free surface for 3dimensional fluid flow simulation had been developed. By the new method, any velocity condition occupied on the free surface of the fliud flow could be treated reasonably.
