数学方程组 meaning in Chinese

mathematical system of equations

Small perturbation assumption was applied to linerarize the nonlinear equations at some trim points , then the stability of the system can be decided through eigen values analysis
模型由包括吊挂物在内的多个部分组成,以机体运动为主运动方程,吊挂物运动为辅助方程,考虑到各部分之间的耦合,为非线性数学方程组。
The numerical methods utilized in solving the set of mathematical equations involve calculating the spatial rate of change of variables , which means a priori grid point value information along the boundary outside the model domain has to be separately provided to set up time - dependent boundary conditions for computing the governing equations
：计算有关数学方程组的数值方法，牵涉到变数在空间的分布变化，故此亦需要另外提供模式范围以外的网格点值，从而按时间设定边界条件，以完成基本方程组的运算。
