说明：  这是一个用TVD格式解决2维弧形翼的计算编程打包，内含多个程序，源自清华大学的计算机系，格式严谨，但是没有多少说明，希望给正在学习TVD的同学些许帮助，属于内部传输资料，现在献上，希望站长采纳，程序可以用来计算2维翼空气动力特性，当然以此类推可以由读者推广到3维中去，或者可以在时间格式上采用龙格库塔5阶格式，变化多多。
(This is a format used to solve two-dimensional TVD calculation of arc-wing programming package, containing a number of procedures, from Tsinghua University, Department of Computer Science, format rigorous, but not much, hoping to TVD of the students are learning a little help, is Internal data transfer, and now offer the hope that owners adopted, the program can be used to calculate the two-dimensional wing aerodynamic characteristics, of course, so readers can be extended to 3 dimension to, or can in the time format used Runge-Kutta 5 order form, change a lot.)
