covolume 中文意思是什麼
covolume
解釋
協體積-
It ' s well known that the covolume methods ( finite volume el - ement methods ) are widely and successfully used in solving many mathematical - physical problems due to their simplicity and local conservation properties in recent years
近年來，有限體積法因其具有局部守衡的性質且實施起來相對較為簡單靈活而被廣泛地應用於求解許多數學物理問題。 -
For solving the corresponding discretization equation, there are few re - sults on the construction of efficient solvers. most existing results only presented the related error estimate for a concrete problem discretized by covolume methods. in this paper, hierarchical basis method, domain decomposition method and precondtioned gmres method are constructed
並且大部分已有研究結果均集中於給出對某一具體問題用有限體積法離散后的誤差估計，而對于如何高效求解其離散方程，這一無論從理論上講，還是從實際應用角度出發都具有重要意義和巨大實用價值的問題，目前這方面的研究結果還很少。
