汽车是公路运输的主要设备,是高速运行的机械。因此,加强对运输车辆的技术管理,保持车辆技术状况良好,是保证运输生产安全,充分发挥运输车辆效能和降低运行消耗的重要保证。改革开放以来,我国公路运输有了很大的发展,到1991年底,公路通车里程达100多万公里,民用汽车保有量已达600余万辆,公路货物周转量约为3400亿吨公里,旅客周转量近2800亿人公里,分别是1980年货物周转量、旅客周转量的13倍和3.8倍。汽车维修行业也得到了相应的发展,到1991年底,全国汽车维修业户已达15万家,从业人员为200多万人,在全国城乡初步形成了一个分布
Cars are the main equipment for road transport and are high-speed machines. Therefore, to strengthen the technical management of transport vehicles and maintain the good technical condition of the vehicles is an important guarantee for ensuring the safety of transport production, giving full play to the efficiency of transport vehicles and reducing the operating consumption. Since the reform and opening up, China’s road transport has made great progress. By the end of 1991, the mileage of roads opened to traffic reached over 1 million kilometers and that of civilian vehicles reached more than 6 million. The turnover of highway goods was about 340 billion tons of kilometers. Nearly 280 billion passenger-kilometers, were the turnover of goods in 1980, passenger turnover of 13 times and 3.8 times. The vehicle maintenance industry has also been the corresponding development, by the end of 1991, the country has reached 150,000 car maintenance households, employing more than 200 million people in urban and rural areas in the country initially formed a distribution
