根据内蒙古大兴安岭部分林区运材汽车的统计资料,运用数理统计原理和回归分析计算,斯康尼亚运材汽车投产使用9年时间行驶40万km,完成运材周转量526万m~3·km左右为其经济使用寿命期。即在该车第二次大修理前结束其运材服役。汽车更新应该服从于经济使用寿命规律。但汽车更新同时受国家财力、汽车工业的发展等因素的影响制约。
According to the statistical data of YunCai Automobiles in some forest regions of Daxinganling, Inner Mongolia, using the principles of mathematical statistics and regression analysis, the operation of Scania transport vehicles took 400,000 km in 9 years and completed the transportation volume of 526,000 m 3 km About its economic life. That is, before the second major overhaul of the car to finish its service. Automotive updates should be subject to the law of economic life.
