So if we see the conclusion of a valid argument is false what do you know? A little bit longer. 如果我们看到有效论点的结论为假,你们知道什么?有一点长。
The comparison between the computed and measured cone/ bit speed ratios proves that the assumption of minimum work is valid, therefore the simulation method can be used for appraising the cone/ bit speed ratio of roller bits. 仿真求得的轮体速比与实测值的对比结果证实最小功假设是可以成立的。用这一仿真试验方法能较好估计牙轮钻头的轮体速比值。
