摘要利用由三角级数和幂级数复合构成的函数项级数的有关性质,得到了一类变系数非齐次调和方程边值问题的级数解。
In this paper by using the property of Fourier series a compound series consisting of trigonometric series and power series is established.
另一方面,对裂隙单元进行三角形单元的有限元网格划分,运用变分原理导出裂隙单元的渗流有限元求解方程。
On the other hand, the fracture elements are discretized into triangular mesh, and the flow finite element equations are derived based on the variational principle.
