The pattern of the finite-difference coefficients is known . 有限差分系数的图式是已知的。
The finite-difference computation must be convergent and stable . 有限差分计算必须收敛和稳定。
We will say that a finite-difference method is convergent if this condition is satisfied . 若满足了这个条件,我们就说有限差分法是收敛的。
To maintain a logical presentation we start with the simplest finite-difference scheme . 为了按逻辑来表达,我们从最简单的有限差分格式开始。
When the rotation at the ends of a loaded strut is restrained, the equation cannot be used in the finite-difference solution . 当受载支柱的端点转动受到约束时,方程不能用于有限差分解。
