用简明易懂的Radzimovsky法推导出用齿数比iA、i0 来计算 2K -H型功率循环型复合行星齿轮机构的功率流、效率和转矩的计算公式。用实例比较了Radzimovsky法与Kpe摮Ｈｅｃ法这两种方法用于效率计算时的最后结果和难易程度 ,结果表明 ,用两种方法求得的效率值相同 ,而Radzimovsky法比Kpe摮Ｈｅｃ法简便庑┓治鲇爰扑闶且恍┳远渌倩翱刂剖讲疃藜侗渌倩涤蒙杓频睦砺刍 Calculate the power flow, efficiency and torque of 2K-H type power cycle compound planetary gear mechanism by using the simple and easy Radzimovsky method to calculate the gear ratio iA, i0. The final results and the degree of difficulty of two methods of Radzimovsky method and Kpe 摮 Hec method are compared with the examples. The results show that the efficiency values ​​obtained by the two methods are the same, while the Radzimovsky method is better than the Kpe 摮 Hec method Simple  庑 ┓ 鲇 rule 鲇 爰 爰 爰 and ┳ far away  渌 Qian  Ao 刂 cut about Tribulus terrestris 渌 渌 Qian  scoop frequency Meng Mu 杓 刍 频
