对流

The outer layers form a convection zone where the gas material transports energy primarily through physical displacement of the gas.

外层形成对流区的天然气输送能源材料主要是通过物理位移的天然气。

The distribution of chloride ions is influenced evidently by local environment conditions, which can make the depth of convection zone changing widely.

氯离子分布受局部环境条件的影响显著，并可导致芯样表面对流区深度发生较大变化。

At the point C, the star develops a convection zone extending from near the surface deep into the extended envelope

在C点，星体产生一个对流区，从表面附近向内扩展到广袤的包层。

So it is expected to reduce the convection in the melt zone and improve the radial segregation in the grown crystal at the same time by the approach of non-uniform magnetic fields.

与此同时，生长界面附近比较均匀的剩余流场使得凝固时杂质浓度的径向分布也相应比较均匀，从而达到抑制对流的同时改善晶体中径向宏分凝的目的。

According to the analysis of the relation of between angle momentum and magneticmomentum, we find that a2 dynamo is main mechanism for the stars withdeep interior convection zone similarly late-M type stars.

从M型主序星的自转周期的和恒星内部对流区随色指数的分布来看，M型主序星的色球活动行为与αΩ发电机理论的预期有明显的差异。

Starting at the outside and going down into the Sun, the zones are the corona, chromosphere, photosphere, convection zone, and finally the core.

从外部开始直到太阳以内，这些带是日冕、色球层、光球层、对流带以及最后的核心。

The Sun's meridional circulation is a massive flow pattern within the Sun that transports hot plasma near the surface from the solar equator to the poles and back to the equator in the deeper layers of the convection zone, similar to a "conveyor belt".

太阳的经向环流，是在靠近太阳的运输，从太阳赤道面的极点和回在对流区，类似"传送带深层赤道热等离子体的大规模流动模式"。

Now that we have some heat, we can use this to cause convection.

既然我们有了一些热，我们就可以用这些来产生对流。

Therefore,the study of the numerical solution method for convection diffusion problems is important in theoretical and practical.

因此，研究对流扩散方程的数值解法有很重要的理论和实际意义。

Regional economic system is an open and complex one, and it has the feature of Benard＇ convection.

区域经济系统是一个开放的复杂巨系统，它具有贝纳尔对流的特点。

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。
