摩擦力

A Coulomb friction model with high accuracy is proposed so that more accurate equations of motion can be established for the transient response of the single-disk rotor which drops onto the back-up bearing as soon as AMB shuts down.

摘要就磁轴承发生故障时转子坠入备用轴承所産生的非线性瞬态响应，提出了摩擦力的计算模型，从理论上建立了更为精确的运动微分方程。

The gas pressure from hard acceleration forces the rings to contact the cylinder around their entire circumference, which is the only way the rings can properly wear into the exact shape of the cylinder to seal the combustion pressure.

这种摩擦力很小且质量不大的部件在消耗能量，里外的压力相差太大，等于单面受压）所以活塞环是无法完全和汽缸壁研磨的，或者说只有很小的一部分在经历研磨的过程。

Setting the saw at the proper cutting depth keeps blade friction to a minimum, removes sawdust from between the blade teeth, results in cooler, faster sawing and reduces the chance of kickback.

设置恰当的锯深，可以使锯片所受的摩擦力最小，锯齿间不存锯末，可以使切割作业更快，部件温度更低，同时也能减少反冲力。

His only equipment, apart from rubber-soled boots, was a bag of chalk slung at the back of his belt, into which he dipped his hands to dry the sweat and improve his grip.

除了一双胶底靴，他仅有的装备便是系在腰带背面的那袋。将这些粉末涂在手上既能驱汗，也能增加他抓取时手上的摩擦力。他不带绳索、钢锥或岩钉。

His only equipment, apart from rubber-soled boots, was a bag of chalk slung at the back of his belt, into which he dipped his hands to dry the sweat and improve his grip.

除了一双胶底靴，他仅有的装备便是系在腰带背面的那袋防滑粉。将这些粉末涂在手上既能驱汗，也能增加他抓取时手上的摩擦力。

Calculations on the basis of the self-consistent approximation are used to study the effects of slit cracks, elliptical cracks and penny-shaped cracks. The influence of slit cracks on the elastic moduli under all kinds of loading conditions is discussed by Betti's reciprocal theorem and Irwin's relation describing the released energy rate of fracture to the stress intensity factors. The friction between the cracks' surfaces is taken into account for the closed cracks.

采用自恰方法研究了狭长型，椭圆型及硬币型裂纹在荷载作用下对弹性常数的影响；采用Betti的互易定理以及lrwin关于断裂能量释放率与应力强度因子的关系，分析了狭长型裂纹在各种应力状态下对弹性常数的影响；分析研究了裂纹闭合时，由于裂纹面上摩擦力的存在，闭合裂纹时弹性常数的影响。

If there were no friction, an object in would never come to a rest.

本句翻译：如果没有摩擦力，那么一个在运动的物体永远也不会停下来。

The equivalent linearization results obtained by probabilistic method are inducted to treat landing gear non linear parameters such as shock absorber air spring force, hydraulic damping and C.

建立了飞机地面滑跑的起落架分析模型；引入了概率平均意义上的当量线性化方法，用该方法处理了起落架缓冲器空气弹簧、油液阻尼和库仑摩擦力以及轮胎刚度和阻尼等非线性参数。

Part of the body like a cord in being long,thin and flexibleA projecting part of a larger piece that helps to provide traction, as on a tire or the sole of a boot.

突缘，凸出部一件大物件上的突出部分，其有利于提供摩擦力，比如在轮胎上或鞋钉上

Emphasis on brand building, production of bearings, with low-noise, low vibration, low friction, high-precision, high sealing, high-functioning, and long-life, no different from noise and other functions.

重视品牌建设，生产的轴承，具有低噪音、低振动、低摩擦力，高精度、高密封性、高运转性，长寿命，无异杂音等功能。

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。
