On the basis of these induced equations, the munerical computation and analyzing are completed, especially for the analyzing and computing the character of helix angle and tooth profile in different section for worm and stator which determines manufacturing for the parts of this kind of drive.

在啮合公式推导的基础上，对超环面行星蜗杆传动的啮合特性进行了数值计算和分析，特别是对与加工、制造这种传动蜗杆和定子紧密相关的蜗杆与定子的螺旋升角及其各个截面的齿形进行了深入的分析与计算。

The tusks grow in a clockwise spiral and can reach almost 10 ft. in length; narwhals themselves are 23 to 26 ft. in length.

这根长牙呈顺时针螺旋状生长，可长达近10英尺，而独角鲸的身体才不过23至26英尺长。

Its basic operation method is a tight mother of the lock that the opens to face afterward, can transpose the angle of the pole of arbitrarily, can process the thread that the different helix rises the Cape, this kind of knife pole has the strength and tenacities to process to slice to pare the dosage exaltation labor rate of production and decline low cost etc. to have the progress towards increasing [10]the knife, improve it is a kind of price less that knife have, yielding results the quicker method.

其基本操作方法是拧开其后面的锁紧螺母，可任意调换蜗杆的角度，可加工不同螺旋升角的螺纹，这种刀杆对增加刀具强度和韧性加工切削用量提高劳动生产率及降低成本等方面有所进步，改进刀具是一种代价较少，收效较快的方法。

Either of two spiral-horned antelopes of the African bush.
