对流

With the sun rising, heat convection gradually to the ground, the clouds will gradually change, that is, to gradually approaching bad weather, local weather grew worse, it is a " alpenglow do not go out."

随着太阳升高，热力对流逐渐向平地发展，云层也会逐渐变密，坏天气将逐渐逼近，本地天气将愈见变坏，这就是"早霞不出门"的原因。

The computation of two-dimensional advection transport using current methods such as Alternating Direction Implicit Method and linear interpolation technique can be subject to numerical attenuation,parasite oscillation and poor reproduction of wave propagation when large time steps are used.

在概化的平面区域内，采用上述方法模拟了二维初始浓度高斯分布和水流激波在旋转速度场及均匀速度场上的对流输移问题，结果表明方法在优化幅值衰减和数值扰动以及计算效率方面具有相当的发展潜力和应用前景

The basic concept in these sections is replacing backward Euler's method by modified backward Eulers's method to approximate the characteristic differential equation and discretizing the convection-diffusion equation at the middle point of the approximate characteristic curve, which will make the convective term get up to second order accuracy.

这三节的基本离散方法是用改进的Euler公式代替向后Euler公式来近似特征微分方程，并且将近似特征线的中点作为离散节点，使得对流项的离散精度提高到二阶，对于扩散项，将其转移到待求时间层进行离散。

Then in the first chapter, the device is modeled to get approximate value of each parameter.

最后对流水中可能出现的器件失效机理进行分析，并提出改进方法。

In India, the flow is from the Arabian Sea and the Indian Ocean.

在印度，这样的区域空气对流来自阿拉伯海和印度洋。

The tests and studies on the rhyolite filtering material show that the functions of the rhyolite material are superior to that of the arenaceous quartz, and the rhyolite flitering material is worth further studying and developing.

对流纹岩滤料的初步试验研究表明，流纹岩滤料的性能明显优于石英砂，是比较理想的天然无机滤料，具有进一步研究开发价值。
