The main problem studied in this thesis are properties of positive solutions to a semi-linear parabolic system with non-local nonlinear sources and null Dirichlet boundary conditions.

中文摘要：本论文主要研究了具有非局部源的半线性抛物系统并附加Dirichlet零边值的解的性质，得到了系统古典解的渐近性分析：blow-up速率、blow-up集、边界层估计等问题。

The main problem studied in this thesis are properties of positive solutions to a semi-linear parabolic system with non-local nonlinear sources and null Dirichlet boundary conditions. We give the analysis about asymptotic property: blow-up rate, blow-up set and blow-up profiles.

This simulation achieves a stable configuration evolution from limiter to lower single-null divertor by using the vertical and horizontal displacement feedback and the current feedback.

数值放电模拟还利用基本的位移控制和等离子体电流控制系统实现了从孔栏位形到下单零偏滤器位形的稳定演变。

With the single-null divertor configuration on the HL-2A tokamak, the ray tracing and the wave power deposit for the ordinary electron cyclotron wave, perpendicularly injected from the weak field side, are analyzed.

在HL-2A单零偏滤器条件下，对由弱场侧沿赤道平面垂直注入的电子回旋寻常波的波迹和波的功率沉积剖面进行了分析计算。

If the function succeeds, the return value is the low-order doubleword of the file size, and, if lpFileSizeHigh is non-NULL, the function puts the high-order doubleword of the file size into the variable pointed to by that parameter

说的很清楚阿。返回值是文件长度的低32位值，而lpFileSizeHigh 是文件长度的高32位值。也就是说，这个函数可以支持文件长度值达到64位。一般文件没有这么大，所以lpFileSizeHigh的值都是0，而返回值就是文件长度了。
