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。

CGRP content in myocardium gradually enhanced from normal group to controls group, and model group's was the highest. We found immunopositive neurons and nerve fibers of nNOS and CGRP by immunochemistry in normal myocardium. They were mainly round-shaped and oval-shaped, also tadpole-shaped、 shuttle-shaped、triangle-shaped、ring-shaped and irregular-shaped. Nv of neurons and nerve fibers in atria were more than in ventricle in some degree; Those in right part of heart were more than in left. Morphology of CGRP neurons changed in model group, the number of ring-shaped neurons increasing, while the round-shaped and oval-shaped decreasing, and Nv and Sv of model group were markedly less than normal. Expression of nNOS mRNA was overly higher than normal group, but CGRP was opposite.

心肌组织CGRP的含量由正常组、实验对照组至CHF组逐渐升高，差异显著；免疫组化研究表明心肌组织中存在nNOS和CGRP免疫阳性神经细胞及纤维，细胞形态多样，正常多以圆形和椭圆形为主，还有梭形、蝌蚪形、三角形、指环形及不规则形，细胞密度心房高于心室，右心高于左心；CHF组CGRP神经细胞形态有一定改变，淡染的指环形细胞增多，而深染圆形或椭圆形细胞减少，其面、数密度均明显低于正常组，差异显著；用RT-PCR测得CHF组nNOS mRNA极度表达，显著高于正常组，而CGRP表达明显低于正常组。
