| 摘 要： | 在测井条件下,系统研究了输运方程的Galerkin变分问题的有限元求解过程。提出了对二维、三维测井区域都适用的有限元剖分方法,在中子测井问题的有限元模拟程序中实现了稳态与非稳态问题的统一处理。计算实例验证了该方法的有效性。

| Abstract: | This paper systematically studies the finite-element method of solving the Galerkin variation problem of the transport equation in well-logging condition and developed a finite-element mesh program which can be used in 2-dimension and 3-dimension well-logging domain.The stationary and non-stationary problem is handled integrately by the well-logging finit-element program.This method is proved to be effective by solving practical problems. |
