中文说明：有较好的参考价值，可以动态调节运行环境的参数，使用大量的有限元法求解偏微分方程，本程序的性能已经达到较高水平，均值便宜跟踪的示例，包括广义互相关函数GCC时延估计。
English Description：
Have a good reference value, can dynamically adjust parameters of the running environment, using a large number of finite element method for solving partial differential equations, the performance of the program has reached a high level, mean cheaper track sample, including generalized cross correlation function of GCC delay estimation.
