We all know that roller, block between hobber and hobber for the imprint, but the artificial division between rolling roller, block roller and embossing roll is a compact, linear three-roll and is consistent, so when the pressure is too large, due to the printing plate is compressed with the roller between a certain amount of sliding friction, thereby allowing the printing plate abrasive.

不小家都懂得，网纹辊、印版滚与不抬印滚之间虽说是滚不抬，但是网纹辊、印版辊与不抬印辊是有不抬缩的，而不一辊的线速量又是分歧的，所以当不弛力过不小时，由于印版被不抬缩会与网纹辊之间爆发必定的滑动摩擦，从而使印版爆发磨损。

Figure 2 printing plate gaskets is higher than the 0.2 ~ 0.3mm hobber pillow, blanket below the occipital hobber 0.05mm, a2, B2 Department produces a smaller convex hull, of course, less friction and sliding, wear plates, no szlama and "" taping, fault-printing plates and high, less hierarchical dot gain, clearly, the life expectancy of the machine, the electrical power consumed less.

图2印版的衬垫矮于滚枕0.2～0.3mm，橡皮布矮于滚枕0.05mm，在A2、B2处爆发的凹包较小，当然摩擦和滑动也多，印版磨损较多，无不推不净和"杠子"障碍爆发，印版的耐印率矮、网不面放大多，条理纯楚，机械的寿命放大，电机耗电也多。

The main results of the investigation are as following:(1) Some important criteria for the design of multi-layer structure are acquired: the ratio of the layer thickness to the contact diameter should be controlled to a value about 0.8; increasing the number of the gradient layers and elasticity modulus of the top layer would benefit to the yield strength and the stress status at the interface.（2）By means of molecular dynamics simulations for a indentation and sliding process, it is discovered that dislocations of 45 direction to the surface occur in the surfaces layer, which is correspond to the direction of the plastic flows observed in the macroscopic continuous medium. The irreversible deformation caused by the dislocation and the atom piles at the surface are responsible for the irreversibility of the force response. They are also the main factors for the friction generation. The temperature and the indentation velocity have significant effects on the deformation behaviors of the material of the surface layer. The yield strength would increase obviously if the indentation velocity is greater than 10 m/s.（3）A method to evaluate the fracture toughness of coating by estimating the crack-density functionβof a Wicker''s indentation was proposed. Meanwhile a new surface treatment technology was developed using non-equilibrium plasma.（4）A MD-FE hybrid method and corresponding software was developed to analysis the tribological behaviors for multiplayer system.

研究主要内容和结果有：（1）得到指导梯度膜设计的几个准则：控制膜层厚度与接触半径比在0.8左右为宜；适当增加梯度层层数和顶层弹性模量，有利于提高抗屈服能力和改善界面处的应力状态；（2）通过对嵌入和滑动摩擦过程的分子动力学模拟，发现表层产生一个与宏观连续介质的塑性流动方向观测一致的45 方向位错；位错造成的不可逆变形和表面的原子堆积，是力的响应不可逆性的原因，也是构成摩擦力的主要因素；温度和嵌入速度对材料变形特性有显著的影响，当嵌入速度大于10 m/s时，屈服强度明显增加；（3）提出压痕裂纹密度系数β半定量判定膜层断裂韧性的方法；并开发出表面强化新工艺；（4）开发出分析表面摩擦学特性的MD-FE复合模拟方法和相应模拟软件。
