随着太钢生产生活系统的发展，太钢东点，与普通环型预应力水泥杆一道完成架设山地区工业负荷和尖草坪地区民用负荷大量任务。

Apply grease to the o-ring and slide the new disc holder into place.

从阀杆上拆卸O形环，用新的更换。

The content of this research is as follows: The structure and the work principle of this worm gearing have been introduced.

主要内容如下：阐述了双滚子包络环面蜗杆传动的结构和传动原理。

A gearing in which each element partially encloses the other is, of course, a double-enveloping worm gearing.

1传动装置，其中每个元素部分，周边有其他的，当然是双包络环面蜗杆传动。

Based on the gear geometry of the double enveloping hourglass worm gearing, the tooth surface of the wheel, which is composed of the so-called the original and new contact surfaces, is derived.

基于齿轮几何形状的双包络环面蜗杆的齿面的车轮，后者是由所谓的原始的和新的接触面，导出。

The double-enveloping hourglass worm gearing is one kind of mechanical transmission drivers, which is developed by China and Japan firstly and is used widely in national defense and civil producing industries.

平面二次包络环面蜗杆传动是由我国和日本率先研究成功的一种机械传动方式，在国防和民用工业领域内得到大量的应用。

Strength analysis of the model of globoidal worm gearing with roller teeth and point engagement by using finite element method is performed.

利用有限元方法对新型滚动式点啮合环面蜗杆进行了基于ANSYS的强度分析。

However, a disadvantage of worm gearing is the high sliding velocities across the teeth, the same as with crossed helical gears.

但是，不利的环面蜗杆传动是高滑动速度全国牙，同时由于带交叉斜齿轮。

The results provide theoretical guide for reasonable selecting of geometric design parameters of double-roller enveloping hourglass worm gearing.

所得结果有助于合理选择双滚子包络环面蜗杆传动的几何设计参数。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
