随着电子技术的发展,矩阵计算方法日益显示出巨大作用。例如人们用有限元件法建立刚度矩阵,研究各种结构的应力分布问题,用矩阵方法,求解三维渗流问题。显然矩阵方法还可以用于水库调节计算。本文介绍一种考虑水库蓄水、来水、用水的相互关系,建立概率矩阵,求解水库蓄水无条件概率分布的方法。用解线性方程组的方法来代替现行的图解组合法。不仅可以提高精度,而且可以直接上机子进行计算,当前电子计算机求解线性方程组巳普遍采用,这样大大加快计算速度。
With the development of electronic technology, the matrix calculation method has increasingly shown a great effect. For example, people use the finite element method to establish the stiffness matrix to study the stress distribution of various structures, using the matrix method to solve the three-dimensional seepage problem. Obviously the matrix method can also be used for reservoir regulation calculations. This paper presents a method that considers the relationship between reservoir water storage, incoming water and water use, establishes the probability matrix and solves the unconditional probability distribution of reservoir water. Use the method of solving linear equations instead of the current graphical combination method. Not only can improve the accuracy, but also can be calculated directly on the machine, the current computer system for solving linear equations has been widely used, thus greatly speeding up the calculation speed.
