摘　　要：本文以液压元件的内泄漏为主线，深入地研究了液压系统运行状态机理、评定指标。提出了反映液压系统工作状态的“状态曲线”，用其进行液压系统的故障预报及维修期的确定。Taking the internal leakage of hydraulic components as main thread, the mechanism of operating status of hydraulic system and evaluation indices are thoroughly studied. A 'Status Curve' reflecting the operating status of hydraulic system is suggested to be used in the failure forecast and determination of service intervals of the hydraulic system.
