In point of power match and minimum realization, the concept of complete power match of the multi-load hydraulic constant pressure systems was proposed. A method for determining the running condition in respect of the minimum power was also presented. 从功率匹配和最小实现的角度,提出了多负载液压恒压网络功率完备匹配的概念及结构条件,给出了基于装机功率最小原则的运行方式的确定方法;
