It is put forward that the hydraulic system is a grey one and its faults possess grey property because of the particularity of the ship hydraulic equipment and its faults,which lays a basis for using the grey system theory in fault diagnosis of hydraulic equipment.
从舰船液压装置及其故障的特殊性出发,提出液压系统是个灰色系统,其故障具有灰色性质,从而为灰色系统理论应用于液压装置的故障诊断提供了前提。
