1950年在制定全国科学技术发展纲要时,牵引动力的发展方向以电力牵引为主,六十年代开始,我国石油在能源平衡中的比重逐年增加,认为我国石油资源比较丰富并考虑战备,牵引动力的发展方向以内燃牵引为主。1973年世界能源危机后,考虑到我国的能源资源条件以及各种牵引的技术经济特性,牵引动力的发展方向转为内电并举以电为主。这个方针对远景发展大家认识比较一致,而近期发展看法不一,提出了发展蒸汽牵引还是内燃牵引的问题。从此出现了蒸汽、内
When formulating the National Program for the Development of Science and Technology in 1950, the direction of development of traction power was mainly electric traction. Since the 1960s, the proportion of China’s oil in the energy balance has been increasing year by year. It is believed that China’s petroleum resources are abundant and war preparations and traction are considered The development of the main internal combustion traction. After the world energy crisis in 1973, considering the conditions of energy resources in our country and the technical and economic characteristics of various traction, the development direction of traction power is shifted to internal power and electricity mainly. This principle is more consistent with the long-term development of everyone, and the recent development has mixed views, raising the issue of developing steam traction or internal combustion traction. Since then there has been steam inside
