查询词典 stroke hole

The article bases on the traditional graphical method,and applies design principle in the references[1],derives the optimizing design methods which under the condition of meeting the fixed slider stroke and the coefficient of variety of stroke velocity,makes the minimum transmission angle of the eccentric crank slider mechanism to maximum(that is the best transmission angle).

曲柄滑块机构在工程上应用十分广泛，传动角的大小是衡量机构传力性能好坏的一个重要指标。通常求解最佳传动角的方法是建立数学模型，在计算机上进行数值求解，本文在传统图解法的基础上，运用文献[1]中的设计原理，推导出在满足给定的滑块行程S和行程速度变化系数K的条件下，使传动

When the threshold for the logistic model was set at the first quartile, this resulted in a sensitivity of 86% for detecting all stroke and a sensitivity of 94% for detecting hemorrhagic stroke.

当Logistic模型的界值设定为第一个四分位数时，结果显示检测出所有卒中的敏感度为86%，而对出血性卒中则为94%。

With two-stroke and four-stroke engines, the bike is an epitome of power on road.

Quot;A start of this much,each free-swimming period has to be this fast,with a certain stroke frequency and stroke lenth,with turns done in these time.

梅森说，开始s是这么多时间，每一次自由泳时间都必须达到这么快，并且在一定的划动频率和华东长度下，这些时间内完成转弯。

If you think of the swing volley as a high ground stroke, it's easy to learn: prepare early with your ground-stroke grip and with the racquet at the height of the ball, hit the ball at its peak, and drive it.

如果您认为回旋球作为一个高射炮，学会是容易的：及早准备与您的地面冲程握把和用球拍触球的高度，击中球在它的最高点的时候，并且驾驭它。

The slice ground stroke lends itself beautifully to the drop shot. There is almost no difference in the stroke until you hit the ball.

打切削球的准备动作更有助于击出完美的小球，因为在拍面接触球之前切削和放小球几乎没有区别。
