| 摘 要： | 本文采用三次样条方法计算了放射性核素从注入井中向多孔岩层裂缝中传输的数值解,并与有限差分解、解析解作了比较。结果表明,三次样条方法在带有放射性衰变的水动力弥散方程的数值计算中,对抑制数值耗散是一种有效的方法。

| Abstract: | Cubic spline method was used to solve numerical model for radio-nuclide transport from injection well into a single fracture in a porous formation, and the results were compared with those of finite difference scheme. It is shown that cubic spline method is effective for restraining numerical dispersion in numerical simulation of hydrodynamic dispersion equations with radioactive decay. |
