压缩气体

Most of the students wrote proofs of their beliefs using Boyle's Law(gas cools when it expands and heats when it is compressed) or somevariant.

大部分学生应用波义尔定律(气体膨胀时变冷而被压缩时变热)或其变型来证明他们的看法。

Core area of the gas is highly compressed to the density of water 150 times.

核心区的气体被极度压缩至水密度的150倍。

A compressed bottle of gas fulminated in front of the painting.

一瓶压缩的气体在画面前爆炸了。

The credit is not generated until the gas is compressed for vehicular use. The U.S.

信用没有引起，直到气体是压缩的为交通工具的使用。

The analysis of a rocket nozzle involves the concept of " steady, one-dimensional compressible fluid flow of an ideal gas".

分析火箭喷嘴，涉及的概念，"稳，一维可压缩流体流动的理想气体"。

In the paper, a mathematical model of borehole gas transient flow in the process of gas drilling is set up and a numerical solution method is put forward on the basis of the unsteady flow theory of compressible fluid.

基于可压缩流体不稳定流动理论，文章建立了气体钻井过程中井内瞬态流动的数学模型并提出了模型的数值解法。

Before the teaching activity, students' misconceptions of "air" concept mainly be, the student thinks the air isn't a kind of material, so the air isn't condensability, don't occupying space, and can't speaking out air current can be become common practice with form, its cause was that: the basic concept for air's quality was wrong and students always conducted incorrect judgment due to the ambiguity of literate meanings.

本研究的结果发现：学童在教学活动之前，有关「空气」的迷思概念主要是，学童认为空气不是一种物质，所以空气不可压缩，不占有空间，并无法说出空气流动可以形成风；其成因是：气体基本性质概念错误和常因字义不清而下判断错误。

Numerical methods based on the continuum hypothesis and molecule kinetic theory are performed to investigate the gaseous flow in the microchannels. The validity of different boundary conditions based on continuum model is examined by DSMC method under different Knudsen number. It is found that the impact of rarefied and compressibility effects are different.

针对微槽道中气体流动的特征，分别采用连续介质模型和分子运动模型简要分析了连续介质模型中不同滑移边界条件的适用范围，并总结出稀薄效应对槽道中压力的的影响和可压缩效应的作用趋势是相反的。

Our Solar System condensed about 10billion years later from the cosmic dust and gas of a supernova and our Earth differentiated into its core, mantle and crust.

我们的太阳系是大约十亿年前，由宇宙尘埃和超行星中的气体压缩而来的，这样我们的地球才有了地心、地幔和地壳。

The technological process and working characteristics of front desiccator and rear-desiccator and the key influencing factors in the operation are expounded.

论述了压缩天然气加气站中设置脱水装置的必要性，气体脱水方法的分类和天然气深度脱水原理，前置式干燥器和后置式干燥器的工艺流程、工作特点、运行中的关键影响因素。
