The main objective of the present work is to study the effect of free surface heat transfer on the thermocapillary flow of high Prandtl number fluids.

本文利用数值方法探讨往复振荡圆柱对渠道内加热块之暂态流场结构及热传特性的影响。

In chapter three, on the basis of the new anomalous magnetic Prandtl number in accretion disks, we study the effect of dissipation on magnetic instability of Keplerian disks.

第三章在新的反常磁普朗特数的基础上，我们研究了耗散过程对开普勒盘磁不稳定性的影响。
