对流

Convection rain is the most common type of rainfall.

最常见的雨是对流雨。

The application of media ' s technology of the convection did the bright prospect finally.

最后对流媒体技术的应用作了美好的展望。

Convection come into being in favor environment, and severe convection development by interaction with environment.

对流是在有利的环境条件下产生的，强对流产生后在与环境的相互作用中发展。

How is heat passed in the air by convection?

热量是怎样通过对流在空气中传递的？

In contrast to the mechanism of conduction and convection , radiation may take place in a perfect vacuum.

与传导和对流的原理不同，辐射可在完全真空中进行。

Convection will go on until all parts of the fluid are of the same temperature .

对流将继续进行，直到液体各部分的温度完全一致。

This form of convectional activity is responsible for thunderstorms.

这种形式的对流活动就是大雷雨形成的原因。

The convectional heat transfer coefficients were measured and analyzed at different Reynolds numbers and constant heat flux.

在定热流边界条件及不同Reynolds数下测量并分析了对流换热系数。

Before the thermal field is calculated, stable temperature rises in each part of the electromagnet are unknown, so it is impossible to determine the power and convectional heat transfer coefficients at the stable temperature rise.

在进行温度场的计算之前，电磁铁各部件的稳态温升是未知量，故线圈达到稳态温升时的发热功率及对流散热系数不能确定。

The machine is helpful to enhance water quality, improve dissolved oxygen concentration in water and water convectional circulation, with strong water-stir capability, which is the key equipment for pond farming.

该机对改良水质，增加水体溶氧条件效果极佳，提水搅水能力强，水体循环对流状况好，是内塘养殖的关键设备。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
