随着工业自动化程度的提高，对机械零件工作的连续性、安全性要求也提高，而实践证明，导致机械运转失效的主要原因是由于活动构件或者联结件在摩擦力的作用下产生的磨损，磨损导致机械的运转失效，更可能引发安全隐患，这其中磨料磨损占整个磨损总量的50％，故越来越多的研究者对抗磨料磨损的材料进行了一系列的研究。

Based on analysis of application deficiencies of these two mechanisms, some improvement advices are advocated.A unified on-grid pricing mechanism, with the consideration of costs of generators and send-out projects, step options, adjustment along with technology advancement and provincial differences is proposed to replace benchmark pricing mechanism.

A modified investment cash flows statement based estimation method of on-grid prices is proposed in the thesis. Return rate of on-grid electricity price should be adjusted dynamically according to the capital asset pricing model.

Compliant mechanisms are defined as mechanisms that gain some or all of their motion due to the relative flexibility of part or all of their members. Therefore, the design method of compliant mechanism is greatly different from that of traditional rigid-body mechanism and the design methodology for compliant mechanism has not been established systemically till now.

柔顺机构是一种依靠自身的部分或全部具有柔性的构件变形来输出运动或力的机构，它的设计理念及方法与传统的刚性机械设计方法有很大的不同，至今未形成系统完整的设计方法，本文针对这一问题，在国家自然科学基金和国家863计划项目的支持下，提出了轨迹输出平面柔顺机构的一整套设计方法。

Based on the equations, the position and attitude of micro flying robot with flapping wings can be controlled.For the rigid structure wing, a double rocker mechanism typical of two DOFs is designed, which is actuated by two PZTs. The mechanism can actuate the rigid wing to realize two DOFs movements. This mechanism has many characteristics, simple instructure, light in weight, reliable in movement, large in range, easy in drive and convenience in control.

Resorting to the Roberts-Chebyshev theorem,we replace the two cranks of a crank-rocker cognate mechanism with a double bar,which is required to satisfy certain geometrical and motion conditions,and we change the mechanism thus reformed into a geared five-bar mechanism so that one of its links can fully rotate with the link connected with it.

借助于Roberts-Chebyshev定理，将曲柄摇杆轨迹同源机构的两曲柄分别用一双杆组代替，并要求双杆组满足一定的几何尺寸条件和运动条件，使变形后的机构为齿轮五杆机构，且满足机构的一个连架杆以及与其相连的连杆能够整周转动。

However,it is the dissipa-tive mechanism,i.e.the mechanism of energy localization that attracts one′sattention for the problem of shock initiation.Since the test result of shock initia-tion about fine-grain explosive charge does not support hot spot ignition model,the author of this dissertation advances that the mechanism of energy localiza-tion is coincident with phonon-fracton crossover of fractal network for ultra-fine-grained charge and,moreover,analyzes the relation between shock sensi-tivity and porosity,which is consistent with shock Hugoniot curve for porousmaterials.
