气流

In the process of modeling, thermotical character and mechanical character of centrifugal compressor are emphased.

在建模过程中，重点对离心式压缩机的热力特性和机械特性做了较深入的研究，其中热力特性着重于离心式压缩机中的气流在各个关键截面参数和特性曲线，机械特性着重于压缩机转子轴系的振动和轴向力。

The computational results show that the velocities in the nozzle are transonic.

研究还表明CFD技术是研究喷气涡流纺喷嘴内气流流动的重要手段。

The numerical results show that tripolar structures are produced when the updraft velocity reaches the maximum value for the strongly-developed cloud,an...

结果表明，对流云上升气流达到极大值时，较强和较弱两块云分别具有三极性和反偶极性电荷分布结构。

However, in electric field computation, the BEM has not much unfould and most of them are limited in the conventional BEM. In the flow field computation, although some achievements have been gained in solving the constant and uncompressible fluid flow by using BEM, but to the inconstant, compressible, nonlinear, transonic flow, such as the flow in the arc quenching chamber in SF6 high voltage circuit breaker, no any report has been published up to now for the reason that the basic solution of this kind of flow has not been found.

目前，在电场计算领域所开展的工作相对较少，而且仅限于传统边界元方法的应用；在计算流体力学领域，近年来虽然一些学者应用边界元法，在解决定常、不可压缩等问题进行了相当深入的研究，获得了若干研究成果，但是对于像SF_6高压断路器灭弧室中存在的非定常、可压缩、非线性、跨音速、具有复杂而且变边界的气流场由于至今尚未找到基本解，而未见研究工作的报道。

When the computation is converged, the discrete phase injection is set in the inlet of the simulation model and the solid particle is tracked by the uniphase coupling model.

当气流场的计算收敛以后，在进口处设定离散相射源，利用单相耦合法跟踪固体颗粒的轨迹。

This cold air current from the land is so forceful that it makes the nearby seas the stormist in the world and renders unlivable those regions whose counterparts at the opposite end of the globe are inhabited.

从陆地上来的冷气流是如此强大以致于附近的海域成为地球上暴风雨最多的地区，并使得其在地球另一端对称处的地区成为不毛之地。

This cold air current from the land is so forceful that it makes the nearby seas the stormist in the world and renders unlivable those regions whose counterparts at the opposite end of the globe are inhabited.

从陆地上来的冷气流是如此强盛以致于四周的海疆成为地球上暴风雨最多的地区，并使得其在地球另一端对称处的地区成为不毛之地。

The air current isn't unnormal to day.

今天气流不太寻常。

His autobiography,"Chasing the Wind", acknowledged his dependence on "partnering" every variation of air and weather to speed his unsteered balloons and his sails.

他在自传---《追风》中承认，只能任着气流和天气的每份变化来加速他那不受控制的气球和帆船。

The possibility of using a reaction jet had interested aircraft designers for a long time, but initially the low speeds of early aircraft and the unsuitably of a piston engine for producing the large high velocity airflow necessary for the jet presented

使用反作用喷气的可能性令飞机设计师们向往已久，但在最初存在很多障碍，这是因为早期飞机的速度很低和活塞发动机不适合于产生&喷气式&所必需的大量高速气流。

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。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
