In this paper, for the nonhydrostatic anelastic equations, in terms of the frequency and group velocity and the vertical scale ranges with group velocity of the wrong sign, the computational properties of the currently used vertical grids are analyzed.
从非静力滞弹性方程组出发 ,从频率、群速和出现错误群速的垂直尺度范围等方面对现有的几种垂直网格进行比较讨论。
The determination of immersion scope of Shuang Yang He Reservoir was not done by theoretical computation of raising level.
对双阳河水库浸没范围确定，不是根据水位壅高，通过理论计算得出，而是根据该水库的季节性蓄水及冬季冻结特点，在兴利水位条件下，地下水壅高时间可确定性和动态观测数据来确定。
