摩擦力

In this paper,the effect of wheel-rail friction force on wheel peeling is researched mainly through the simulation test.

本文主要通过模拟试验研究轮轨摩擦力对车轮剥离的影响。

Adhesive friction, as of a wheel on a track or a tire on a road.

附着摩擦力，如车轮在轨道上或轮胎在路面上的

You see, he had forgotten about friction.

你可以想象，他忘了摩擦力。

Due to the existing of nonlinear friction, it is difficult to model in the traditional way.

由于非线性摩擦力的存在，很难用传统的方法对其进行建模。

The cost of transportation is the major friction in the market competition.

运输成本是市场竞争中的主要"摩擦力"。

The size of the toy car -- The size of the surface can also affect the frictional force.

玩具汽车的体型--此外，物体的形状也会影响摩擦力的强度。

A new method is used to reduce the side frictional force in the tests, and the validity of this method is demonstrated through comparison tests.

试验中，研究了一种减小侧壁摩擦力的方法，并通过是否减轻摩擦的对比试验，论证了方法的有效性。

Frictional forces may also act when there is no relative motion.

在无相对运动的情况下，也可以有摩擦力的作用。

In a theoretically frictionless, or ideal, machine, the work input and work output are equal, and the efficiency would be 1, or 100%.

理论上，一个无摩擦力的，或者说是理想的机器，输入和输出的功相等，因此效率是1，或者说是100%。

In a theoretically frictionless, or ideal, machine, the work input and work output are equal, and the efficiency would be 1

理论上，一个无摩擦力的，或者说是理想的机器，输入和输出的功相等，因此效率是1，或者说是100%。

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。
