Because the workpiece is in dynamic balance, the resultant moment acting on it should be zero. Introducing the moment from lapping tool and press head a moving differential equation is built. In this equation only workpiece rotating speed is unknown. It means that workpiece rotating speed can be got by this equation. Since there is a transcendental function in integral function of the equation an analytic result can not be got, only digital result can be got by a computer. Thus a change rule of workpiece rotating speed with lapping parameters is known, e.g. the radius of press disc ball socket, radius of press head ball, the distance between the workpiece rotating axis and lapping tool rotating axis, workpiece radius, modulus of elasticity of the press head and press disc, friction coefficients between the lapping tool and workpiece, and between the head and disc, pressure between the lapping tool and workpiece and pressure between the press head and press disc.

因工件处于动态平衡状态，其上所受到的来自于磨具和压头的力矩应相等，将二力矩表达式联立，建立工件运动微分方程，该方程中只有工件的旋转角速度是未知量，因此可以求出工件旋转角速度，但该方程积分式中含有超越函数，得不出解析解，只能通过计算机求出数值解，得出工件旋转角速度随各研磨参数的变化规律，如压盖球座半径、压头的球头半径、工件回转中心相对磨具回转中心的偏心距、工件半径、压头和压盖材料的弹性模量、磨具与工件间的摩擦系数、压头压盖间的摩擦系数、磨具与工件间的压强、压头压盖间的压力等。

Caused by the brake disc brake on back wheel should not have four kinds of spaces possible: First, the foot brake 5 exhaust inlets, high pressure gas instinct Pai people the atmosphere, caused by gas-liquid master cylinder should not spring back to place, cause the system Oil will move the brake disc brake wheel cylinder piston top dead can not come back to places; are gas-liquid two disc brake master cylinder to the tubing plug, resulting in brake wheel cylinder piston can not come back to places; are three master cylinder of gas-liquid Can not spring back to their own spaces, brake fluid under high pressure gas, liquid should not return to the master cylinder reservoir chamber, resulting in brake wheel cylinder piston can not come back to places; are four wheel disc brake piston brake system because of moving fluid dirty or rusty Pistons Can not Back-bit card dead.

造成盘式制动器上的制动分泵不能回位有4种可能：一是脚制动阀5的排气口堵塞，高压气体本能排人大气，造成气液总泵的弹簧不能回位，导致制动油将盘式制动器的制动分泵活塞顶死而不能回位；二是气液总泵至盘式制动器的油管堵塞，造成制动分泵活塞不能回位；三是气液总泵的弹簧本身不能回位，制动液在高压气体作用下，不能回到气液总泵的储油室，从而造成制动分泵活塞不能回位；四是盘式制动器制动分泵活塞由于制动液太脏或活塞生锈卡死而不能回位。

Caused by disc brake on the brake Wheel Cylinder could not return to places 4 possible: First, 5 foot brake valve exhaust port blocking, high-pressure gas instinct platoon atmosphere, caused by gas-liquid master cylinder of the spring could not return to place, resulting in the system move oil, brake disc brake Wheel Cylinder Piston top dead and could not return to places; second is to the disc brake master cylinder gas-liquid pipeline blockage, resulting in brake Cylinder piston can not return to place; third master cylinder of the gas-liquid Spring itself can not return to position, brake fluid under high pressure gas can not return Axial pump to gas-liquid master cylinder reservoir chamber, resulting in brake Cylinder piston can not return to places; Fourth Wheel Cylinder piston disc brake system, due to moving fluid dirty or rusty card dead and can not return to the piston position.

Media Code describes the origin and quality of the disc, which is produced by the stamper disc recording decisions, and a stamper can make about 30 million recordable disc, the recordable disc stamper as the " future generations ", and they share a common" genetic ", and this is Media code.

Media Code说明了盘片的出身和素质，它是由制作刻录盘的母盘决定的，而一张母盘可以制作大约30万左右的刻录盘，这些刻录盘就像母盘的"后代"，它们拥有共同的"基因"，这就是Media code。

Some evidence indicates that the combination of extrinsic, intrinsic and genetic factors all play a role to cause the disc degeneration, with a progressive decrease in proteoglycan content leading to dehydration of the nucleus pulposus, and Type Ⅰ collagen begins to appear in the matrix, the ratio between Type Ⅰ and Type Ⅱ increases. All these cause the swelling pressure, disc height and the disc load bearing ability decrease. The disc progressively herniate and cause radiculopathy and myelopathy.

内因、外因及遗传方面的诸多因素导致椎间盘逐步退变后，其实质就是基质中蛋白多糖的减少，含水量降低，Ⅰ型胶原出现在基质中，Ⅰ、Ⅱ型胶原的比例明显上升，髓核呈纤维样改变，导致椎间盘的膨胀压降低，承重能力下降，椎间高度降低，椎间盘承受的重力不能平均地向各方向传递，致使纤维环疲劳、破裂、髓核突出，造成脊髓或马尾神经受压，引起严重后果。

By means of equalizing the histogram, the contrast of original thermal image is enhanced; then image region of the disc surface of insulator is intercepted manually; through the envelope of the smoothened histogram of thermal image the segmentation threshold is extracted and the morphological filtering is applied to the threshold- segmented binarized image to obtain insulator disc surface image and background image, and then 10 infrared image features of insulator disc surface image and background image, such as the highest temperature, the lowest temperature, mean temperature, variance of temperature distribution of both kinds of images, as well as maximum temperature rise and mean temperature rise of insulator disc surface relative to background, are extracted; finally, the good and bad features are discriminated by single factor variance analysis, thus the feature selection is implemented.
