Based on the method of minimizing maximum workpiece errors,the circular parameters of normal profile of spline hobs are optimized to obtain optimal circular parameters of the hob by analyzing workpiece errors.

通过对工件齿形误差的分析，根据最大误差最小法的基本原理，对矩形花键滚刀法向齿形的圆弧参数进行优化，使滚刀加工出的工件齿形误差最

He plunged into the swimming tank or went hunting with the Judge's sons;I he escorted Mollie and Alice, the Judge's daughters, on long twilight or early morning rambles; on wintry nights he lay at the Judge's feet before the roaring library fire; he carried the Judge's grandsons on his back, or rolled them in the grass, and guarded their footsteps through wild adventures down to the fountain in the stable yard, and even beyond, where the paddocks were, and the berry patches.

他跟法官的少爷们跳进游泳池或出去打猎。当法官的女儿默里和艾丽丝在黄昏或凌晨长途漫步时，他护送她们。冬天的夜晚在书房烧得正旺的火炉前，他趴在法官的脚下，他把法官的外孙们驮在背上，或是让他们在草地上滚来滚去，并保护他们徒步进行疯狂的探险；一直到马厩那里的水龙头那儿，甚至更远，到牧场和草莓圃那儿。

ACCORDING TO THE SYNTHETIC ANALYSIS OF STRESSESD STATE OF THE ROLLING SHEAR,THE EQUATION OF APPLIED FORCE OF THE SHEAR'S CRACK SHAFT WAS GIVEN,AND THE MOMENT ON EACH CRANK ARM OF THE CRANK SHAFT BE INDENTIFIED.

根据对滚切剪受力状况的综合分析，建立了滚切剪曲轴受力方程，并进一步确定了曲轴两个曲柄上的力矩和总的力矩，从而设计出曲轴的总体结构。

Cylindrical roller bearings are separable bearings , easy to install and removal of the two rings can be used tight fit; Dingxin special sales of cylindrical roller bearings from SKF, NSK, FAG, NTN, NMB, KOYO, NACHI.

圆柱滚子轴承是可分离轴承，便于安装和拆卸，两个套圈都可以采用紧配合；鼎鑫特公司销售的圆柱滚子轴承来自SKF，NSK，FAG，NTN，NMB，KOYO，NACHI。

The lady half rose from her seat, letting her work, which was large and awkward, fall from her lap as she did so, and dropping a reel of cotton, which rolled away upon the polished oaken flooring beyond the margin of the Turkey carpet.

女士从座位上稍稍欠了一下身子，放下她的针线活儿，那活儿又大又难处理，从她的怀中掉了下来，一卷棉纱线还滚了出来，滚到土耳其地毯外边儿的、漆得锃亮的栎本地板上去了。

While the experimental side force distribution over a slender body with a blunt ogive nose is basically consistent with the curve of the analogy predicted, and the characteristic points and half cycle of the experimental curve are basically constant with the roll angle changing 360°. But the local maximums in the curve are not the results as the analogy predicted, which is an important flow feature of 3-D slender body than that of 2-D cylinder.

而钝头拱形细长体在大迎角下的截面侧向力分布与脉冲起动横流比拟方法预测的侧向力曲线的形状是基本相同的，而且随着滚转角旋转360°，截面侧向力分布曲线的特征点和半周期基本保持不变，即它们都基本上不受滚转角变化的影响；但是截面侧向力分布曲线极值点形成的原因却是不同的，这是细长体绕流区别于二维圆柱绕流的一个重要特性。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
