摩擦力

Without friction , the brake would not work.

如果没有摩擦力，制动器就不能制动。

The pneumatic friction clutch and brake of the mechanical press based on the former analysis is also investigated. The main research work is shown as follows:(1) The nonlinear mathematical model of the system is established, and the valve characteristics and the friction force of the system are tested.

本文主要进行了以下几个方面的研究： 1气动伺服系统是一个具有较强非线性的系统，本文建立了该系统的非线性数学模型，并对气缸的摩擦力及阀的特性进行了实验研究。

The brake shoes apply friction to the brake drum, forcing it and wheel to slow or stop.

制动蹄对制动鼓所产生的摩擦力迫使制动鼓和车轮减速或停车。

The Brake shoes apply friction to the Brake drum , forcing it and the wheel to slow or stop.

制动蹄对制动鼓所产生的摩擦力迫使制动鼓和车轮减速或停车。

It starts with new mechanical components that significantly increase brake friction and improve stopping power, while effectively eliminating brake fade.

由于使用了可显著增加刹车摩擦力的新元件，有效消除了制动失效情况。

With the pressure released, there is no friction at work in the clutch , and the power flow is therefore interrupted.

随着压力的减小，离合器工作状态下的摩擦力消失，动力被切断。

With the pressure released, there is no friction at work in the clutch, and the power flow is therefore interrupt ed.

随着压力的减小，离合器工作状态下的摩擦力消失，动力被切断。

The drill uses twin disc constant friction clutch, which transmits power by means of friction.

钻机采用的是双片常接合摩擦式离合器，它是利用摩擦力传递动力的。

In order to achieve high precision position control in pneumatic system, friction must be compensated for.

在气动比例控制系统中，摩擦力的存在是影响其定位精度的一个关键因素。

We analyze the principle of stick-slip motion deeply. From foregoing analysis a result was made that dry friction is the main factor in influencing low speed capability of electro-hydraulic servo system. Dry friction must be compensated for improving the low speed performance. Then a nonlinear model with friction is set up and control methods is discussed.

深入分析了汽轮发电机转速不稳定的原因是由于电液伺服系统在低速区性能不稳定，而影响电液伺服系统低速性能的主要因素是干摩擦，要提高电液伺服系统的低速性能必须对摩擦力进行补偿。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
