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.

Let -off systems fall into one of three major categories. The simplest let- off system is known as negative let- off. This system merely consists of a brake continually applied to the warp beam to retard the motion of the beam.

送经系统有三种，最简单的是消极式送经机构，该机构仅仅是靠一个制动机构连续地给织轴施加制动作用以阻止织轴的转动。

Because windup partly depends on the N-methyl-d-aspartate receptor, action at this receptor is not critical to immobility produced by these anesthetics.

因为windup部分依赖于NMDA受体，此受体的活动在这些麻醉药产生的制动作用中并不关键。

To 26. 23, P ＜0. 01.CONCLUSION: Chlamys farreri is capable of increasing Bcl-2 protein and decreasing Bax protein in cerebral penumbra to brake the initiation of neuron apoptosis after ischemia-reperfusion and preserve neuronic function in penumbra.

扇贝多肽能够上调脑缺血半影区内抑制神经细胞凋亡的Bcl-2蛋白水平，同时降低半影区内诱导神经细胞凋亡的Bax蛋白的表达，从而在阻止脑缺血再灌注后细胞凋亡启动中起制动作用，保护脑缺血后半影区内神经元的功能。

Therefore, brake action's principle is the travel in automobile energy transformation for the heat energy, thus realizes causes the goal which the automobile decelerates.

所以，制动作用的原理就是把行驶中的汽车动能转换为热能从而实现使汽车减速的目的。

BACKGROUND: Aromatic anesthetics exhibit a wide range of N -methyl-d-aspartate receptor inhibitory potencies and immobilizing activities.

背景：芳香族麻醉剂显示出广泛的抑制 N -甲基-d-天冬氨酸受体的作用和制动作用。

When the hydraulic pressure power supply stops or controls the solenoid valve opens, in driving pliers' pressure oil pressure vanishing, the piston under the precompression brake block spring's function rapidly promotes, affects on the friction liner and presses to is applied the brake the body, simultaneously the driven pliers in the driving pliers and under connecting bolt's function, lead through the glide guide pillar's function rub the liner to press to are applied the brake the sleeve to become the brake.

当液压动力源停止或控制电磁阀打开时，主动钳内的压力油压力消失，活塞在预压的制动弹簧的作用下迅速推出，作用在摩擦衬垫上并压向被制动体，同时从动钳在主动钳和连接螺栓的作用下，通过滑动导柱的作用带动摩擦衬垫压向被制动体完成制动。

Discussed shallowly the automobile braking system is without a doubt, plays is decelerating, role and so on service brake:, in vehicle brake braking systems is one of vehicles most important safety devices, and the braking system already became the vehicles driving secure to a certain extent pronoun.

继续下面文章的英文翻译，大家帮帮忙啊浅谈汽车制动系统毋庸置疑，起着减速、行车制动、驻车制动等作用的制动系统是车辆最重要的安全装置之一，并且在一定程度上制动系统已经成为车辆主动安全性的代名词。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
