The clutch contains friction disk about 300 millimetre in diameter. It also contains a spring arrangement and a pressure plate for pressing this disk tightly against the smooth rear face of the flywheel.

离合器有一直径大约300毫米，并带有摩擦衬片的圆盘，还有一弹簧装置和一压力盘，用来把摩擦盘紧紧地压在飞轮光滑的壁面上。

Here's the basic difference: when the planets in our solar system first formed, they were swimming through a disk-shaped cloud of gas. Their passage roiled and compressed the gas, and the gravity of the compressed gas in turn pulled on the proto-planets.

根本的差别在于：当行星在太阳系中首次形成时，它们正漂浮着通过一片圆盘状的气体云，于是它们前进的道路受到波动同时也压缩了气体，被压缩气体的引力反过来拉住了这些初生的行星。

Round wheel with air, or an aging hose皮碗bad wheel or front wheel brake drum of a missing side of a round, tire pressure before the two are inconsistent, a friction-chip front-side oil, wet, hardening, exposed rivets.

轮分泵有空气，软管老化或分泵皮碗不良或前轮某侧制动鼓失圆，两前轮胎气压不一致，某侧前轮磨擦片油污、水湿、硬化、铆钉外露。

Patients with degenerative arthritis of the X-ray, the right hip looks smooth Yuangun is in normal health of the joint; edge of the left hip is not formed, that cartilage hyperplasia, leading to the surface wear.

退化性关节炎病患的X光片，右侧髋关节看起来平滑圆滚，是健康正常的关节；左侧髋关节边缘不平整，可见软骨增生，导致表面磨损。

The constructed surface not only has the same structure to the bicubic Coons pacth, but also it can help us to obtain different surfaces by changing the values of the parameters. Furthermore, it can accurately represent torus、ellipsoid and so on.

所构造的曲面不仅具有双三次Coons曲面片的相似的结构，可以通过改变参数，得到不同的曲面片，而且还能精确地表示圆环面、球面、椭球面等二次曲面。

Why, when grandmother's tears fall upon the rose, and she is looking at it, the rose revives, and fills the room with its fragrance; the walls vanish as in a mist, and all around her is the glorious green wood, where in summer the sunlight streams through thick foliage; and grandmother, why she is young again, a charming maiden, fresh as a rose, with round, rosy cheeks, fair, bright ringlets, and a figure pretty and graceful; but the eyes, those mild, saintly eyes, are the same,- they have been left to grandmother.

这朵玫瑰张开了，于是整个房间就充满了香气。四面的墙都向下陷落，好像它们只不过是一层烟雾似的。她的周围出现了一片美丽的绿树林；阳光从树叶中间渗进来。这时祖母--嗯，她又变得年轻起来。她是一个美丽的小姑娘，长着一头金黄色的卷发，红红的圆脸庞，又好看，又秀气，任何玫瑰都没有她这样鲜艳。

Cdc42 and Rac1 have similar effects on cytoskeleton. They both promote the actin polymerization in the cell and profit the formation of filopodia and lamelipodia respectively.

Cdc42和Rac促进细胞内肌动蛋白聚合，分别有利于丝状伪足和片状伪足的形成；而RhoA可能具有与Cdc42 和Rac相反的效果，通常造成细胞边缘和突起的收缩及胞体变圆。

The efficient conversion of mass into energy by friction in the accretion disk of a black hole seems to be the only explanation for the copious amounts of energy generated by such objects.

在黑洞增大圆盘片靠摩擦质量有效转化为能量好像只能解释靠这样的物体产生的大量能量。

MS809: Small round plane door lock, adopt multi-lock plate structure, better safety performance, hook steel pin, better lock start .

简介：MS809：小型圆平面门锁，采用多锁片结构，安全性能更佳，钩形钢栓，开启更佳。

A circle is placed at the launch point to improve the interaction between the electron beam and the fields supported by the slow wave structure, thus to control the beam current density at the launch point, and to minimize the loss of the electron beam energy. The inaner radii of the extractor vanes are slightly larger than those of other SWS vanes, which increases the axial group velocity and enhances the microwave output power and efficiency. Implementation of two RF choke vanes stops the leakage of microwave pulse power toward the diode, and makes the device more compact than the conventional MILO.

该振荡器在阴极电子发射起点加圆环，控制此处电子束的发射密度，来减少电子能量的损耗，改善束－波互作用；逐渐加大慢波结构的后两个叶片的内半径，增大微波群速度，便于谐振腔中的能量输出，提高微波输出效率；采用两个扼流片有效地阻止了微波功率向二极管区泄漏，相应减小了器件的尺寸。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
