Because of the fact, the bearing capacity of the whole drive cannot be developed well enough. To improve the performances of the load-capacity, transmission efficiency, and reliability of mechanical drive, we originally developed some designs of the double crank ring-plate-type cycloid planetary drive. The new-type drive keeps all the natural advantages, which is of multi-tooth mesh, small mesh angle, and hardened tooth flank of gears. Moreover, The drive does not need the special output unit as the ring-plate-type drive does, so that the rigidity of the output shaft becomes much higher. Since the tumbler bearing is placed outside the cycloidal gear, the size of the bearing is no longer restricted to any extent.

为大幅度提高其承载能力、传动效率和可靠性诸指标，我们创新研究出来的多种结构双曲柄环板式针摆行星传动，其特点是不仅保留着原摆线针轮行星减速器同时啮合齿数多，总法向力与总圆周力间夹角小，摆线轮与针轮齿均为硬齿面等本质上的优点；而且又具有环板式传动省去输出机构且输出轴刚性好，转臂轴承移至行星轮外，从而传递的转矩可以成倍提高的优点。

The reason of low system efficiency of the mechanical lifting is: unavailable match between transformer and asynchronous motor with large capacity of equipment and large self-consumption; large average no load less of Y series electrical machinery (31.4% of the total oilfield electrical machinery) with 2.86kw; limited adjustable extent of stroke of the electrical machinery in low-liquid produced wells with minimum value of 4 times per minute for limitation of minimum rotation of the electrical machinery and minimum arc of contact of pulley. Energy consumption will be waste for 1 to 1.5 times per minute is enough.

分析显示，造成抽油机系统效率低的原因主要是：变压器与异步电动机之间匹配方式不合理，设备容量大，自身损耗大；占油田电机总量31.4%的Y系列电机的平均空载损耗大，为2.86kW；低产液井电机的冲次可调范围有限，受电机最低转度和皮带轮最小包角限制，其最小冲次仅可调到4次／min，但1~1.5次／min的冲次即可满足生产需要，造成能耗浪费。

The first industrial production teflon thin film majority uses have re-equipped the plank veneer peeling lathe turns on lathe cuts the processing, this traditional veneer peeling lathe uses the mechanical drive control generally, produces not only the thin film the quality is not high, the reliability is bad; Moreover in the production process the noise is big, consumes energy much, the production efficiency is not high, is unable to adapt the now industrial production demand.

目前工业生产的聚四氟乙烯薄膜大多数使用改装过的木板旋切机旋切加工而得，这种传统旋切机一般采用机械传动控制，生产出来的薄膜不仅质量不高，可靠性差；而且生产过程中噪音大，耗能多，生产效率不高，无法适应当今的工业生产需求。

The 第一工业生产聚四氟乙烯打开车床裁减处理，这台传统表面饰板削皮车床一般使用机械驱动控制，生产不仅质量不是高的薄膜，可靠性是坏；而且在生产过程中噪声大，消耗能量，生产效率不是高的，无法适应现在工业生产demand。

As an important branch in CAD, AEC (Architecture, Engineering, Construction) is different from mechanical CAD. It has been widely used to improve quality and efficiency of engineering design.

工程CAD是计算机辅助设计的一个重要分支，在设计领域有着广泛的应用，对于提高设计水平、设计质量和设计效率有很大的帮助。

The results showed that Japanese cedar, Ma bamboo and Makino bamboo all had a good liquefaction efficiency as liquefied in polyethylene glycol/glycerol co-solvent with H2SO4 as a catalyst. The properties of PU foams made from liquefied woody material were influenced by the formulas of PU resins. Wherein, the PU foams made with a higher ratio of isocyanate would had a more complete crosslinking structure, a better mechanical properties and solvent resistance, and a lower water adsorption.

由试验结果得知，以PEG-400/glycerol为液化药剂，H2SO4为催化剂对柳杉、麻竹及桂竹均有良好之液化效果；液化木质材料所制造PU发泡体之性质受各成分调配比例所影响，其中异氰酸酯比例较高者，其PU树脂中液化木质材料之架桥反应较完全，发泡体机械性能及耐溶剂性较高，吸水性较低。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
