摘要:

对无弥散项的可压缩核废料污染问题模型建立修正迎风差分格式, 并进行了收敛性分析,最后给出其l^2误差估计.

关键词: 可压缩, 核废料污染, 修正迎风

Abstract:

A modified upwind difference procedure is formulated to treat the model of contamination by compressible nuclear waste without dispersion. Convergence analysis is processed and finally the l^2 error estimate is derived.

Key words: Compressible, Contamination by nuclear waste, Modified upwind
