摩擦力

In this work,atomic force microscopy,near-field scanning optical microscopy,laser scanning confocal microscopy and quantum dot labeling were used to investigate the biophysical properties(the parameters including morphology,membrane nanostructures,membrane pore, friction distribution,adhesion properties,specific interaction of antigen-antibody,distribution mode of membrane receptors and so on) of T lymphocytes stimulated by phorbol dibutyrate plus ionomycin at nanoscale.

本论文基于AFM和NSOM，结合量子点标记及激光共聚焦等技术，以人外周血T淋巴细胞为研究对象，在纳米尺度研究了活化前后以及不同活化阶段T细胞生物物理特性的变化，即细胞形态结构、膜表面纳米结构、膜孔变化、膜表面摩擦力分布、膜表面粘附特性、抗原-抗体间特异性相互作用力、膜表面受体分子分布模式等。

Fixtureless join of scraper conveyor cable pan using in mechanize working face;2. The join of hydraulic tractive shearer with electromotor crosswise arrangement;3. With the help of an example of drawing elastic loop s join into in-phase Gear of Boots blowers,dynamic system software ADAMS is utilized to analyze its driving process.

The end of the spring is compressed against an interior surface of the ratchet head to frictionally retain the shank spindle and pawl of the ratchet during the resetting stroke of the ratchet yoke.

弹簧的端头压在棘轮头的内表面上，以便在棘轮轭的复位冲程中依靠摩擦力卡住棘轮的芯轴体和爪。

The boots didn't require any more than a day's break-in and only got more comfortable after only a couple of days' wear. Traction on smooth surfaces is excellent, thanks to the grippy soles.

鞋子在不到一天的时间内就达到测试目的了，而且在穿了几天后就越加的舒服，光滑表面的摩擦力是很棒的，这都多亏了摩擦鞋底。

As the results, the ultra-thin films of 500SN and hexadecane exhibited nonlinear shearing response, which was different from that of the Newtonian fluids in their bulk state.

结果表明：在超薄膜润滑条件下，5 0 0 SN和十六烷均表现出明显的非牛顿剪切响应，即剪切稀释现象；摩擦力幅值随剪切速度的增大急剧上升到最大值，然后下降至某一固定值附近并产生波动；剪切挤压下的临界膜厚小于静态挤压的临界膜厚，剪切运动对吸附层有序结构产生破坏作用

To control the body height of vehicle with hydropneumatic active suspension system, this paper presents a new control strategy to eliminate the oscillation arising from friction force and occurring in conventional PID control.

对采用油气主动悬架的车辆车身高度进行控制时，由于摩擦力的影响，采用根据线性模型设计的常规 PID等传统控制策略系统存在振荡现象。

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。
