“动力装备程度高的拖拉机或动力装置”这种说法常常被用来替代大功率拖拉机或其他大功率动力装置的习惯概念,这是不恰当的。其实,它同其他以单位重量折算的指标一样,动力装备程度是用拖拉机单位重量的发动机功率千瓦数来表示。它不能成为一种特征参数,因为,所有拖拉机在不同程度上都具有一定的动力装备程度: It is not appropriate that the phrase “tractor or powerplant with a high degree of power equipment” is often used to replace the customary concept of high-power tractors or other high-power power units. In fact, it is the same as the other indicators converted by unit weight. The degree of power equipment is expressed in kilowatts of engine power per unit of tractor weight. It can not be a characteristic parameter because all tractors have a degree of power equipment to varying degrees:
