本文回顾了我国内燃、电力机车修制的发展过程,指出计划预防修已不符合目前形势的要求,应向状态预防修过渡。还进一步指出,诊断状态修是修制改革的高级阶段,要完成这个阶段的任务,需要正确导向和艰苦努力。从调研、定型、试点到全面推行,大约需要20年的时间。 This paper reviews the development process of internal combustion and electric locomotive repair in our country, and points out that the planned prevention and repair work has not met the requirements of the current situation and should be transitioned to the state prevention and repair. It is further pointed out that the diagnosis of state repair is an advanced stage in the reform of the system. To accomplish the tasks of this phase, we must correctly guide and work hard. It takes about 20 years from researching, styling, piloting to full implementation.
