摘　　要：比较了泰山２５型拖拉机机组的理论起步过程与实测起步过程。现行滑磨功的理论公式是在作了３条假定的情况下导出的，计算值比实测值小，为保证离合器可靠工作，应对现行公式加以修正。文中给出了修正公式并推荐了修正系数的取值范围。The paper compares the theoretical initiation process of a Taishan 25 tractor engine with its practical process. The result shows that the measure characteristics of the clutch are in good agreement with the junction characteristics in theory. The current formula for slipping work is deduced under the three assumptions, and its computational value is smaller than its measured value. To assure a reliable work of the clutch, we modified the current formula. The paper gives the slope of correction factor. Though the best junction time can determine in theory, it is difficult to come true in practice. Generally, it is determined by driver's experience.
