摘要

抽象。本研究探讨了两种奖励元素方法(DRBEM)的平河道的固定渗透问题。这个问题的构建者方程是理查德方程。利用Kirchhoff的转化和液压传导指数的关系，Richard方程把它变成了矩阵潜在通量中的固定代谢方程。MFP中的混入方程随后被修改为Helmholtz方程。通过用不同的累累代理元素方法(DRBEM)完成对数字路径的静止分析，通过使用不同的外部和内部错位点(DRBEM)来完成对数字通配符的修改。更多的是，数字解决方案和分析解决方案的关键词:这项研究探讨了稳定解决的问题，涉及两种对接受奖励元素方法(DRBEM)的固定渠道的问题。管理这个问题的方程是Richard的方程。使用Kirchhoff变压器和外联补助关系，Richard的方程正在不断地在MFP表里插入方程。然后转换成修改Helmholtz方程。在修饰的Helmholtz方程中，稳定的模式的持续渗透。《新解决方案》是通过通过双重磨损条例条例法(DRBEM)实现的。再加上，nu梅里和分析解决方案就被补充了。渗透，平巷，修改Helmholtz方程，DRBEM

Persamaan infiltrasi dalam MFP selanjutnya diubah ke dalam persamaan Helmholtz termodifikasi.
