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。

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。
