最低速度;最小速度
The minimum speed on the freeway is 45 kms per hour.
这条高速公路上的最低时速为45公里.
Further analysis shows that the reasons for reducing energy consumption can not continue because the speed was stable in operation due to the minimum speed.
进一步分析表明,能耗不能降低的原因仍然是因为转速被稳定在最低转速下运行所致。
What's more, with maximum speed ratio, minimum speed ratio of transmission system and speed ratio of reverse gear having been calculated, design method of structural parameters has been brought out.
对传动系统的最大速比、最小速比和倒档速比进行了计算分析,提出了回流式无级自动变速传动系统的结构参数设计方法。
