【摘要】 在对北方林区运材汽车的生产情况作了大量调查、统计和实测的基础上,本文对北方林区运材汽车运行油耗量的现状和影响因素进行了分析,运用数理统计的方法对实测数据进行了分析,确定了影响汽车运材油耗量的主要因素,并用多元回归分析法建立了运材汽车运行油耗量的多元经验回归方程,从而提供了一种对运材汽车运行油耗量进行估算和预测的方法,以便为科学地制订运材油耗量定额提供依据。更多还原

【Abstract】 On the basis of investigation, statistics and measurement to transporting conditions of lumber trucks in North forest areas of China, this paper analyses the current situation and the effect factors of the transportating fuel consumptions of lumber trucks in North forest areas; analyses the measuring data with mathematical statistics; defines the main factors to affect the transporting fuel consumptions of lumber trucks. And it puts forward lumber trucks with poly-regres-sion equation of the transporting fuel consumptions of lumber trucks with poly-regression analysis. Thereby, it provides a method with which we can reckon and calculate the transporting fuel consumptions of lumber trucks, so as to provide a basis for working out the quota of transporing fuel consumptions of lumber trucks scientifically.更多还原
