The results show that although economic growth in the northwest region as the whole has been physical capital-driven, elasticity and contribution rate of human capital in each province has been relatively high, indicating the spillover effect of human capital These findings suggest that effectively and steadily speeding up human capital accumulation while increasing capital investment may enhance the level of economic development in the northwestern China, thus reducing the disparity between this region and the eastern region.

Graceful course observes Paasche carefully, discovered the secret that octopus cultivates eventually, original, the overgrow on its branch fructification pod, the fructification that a few belts prick is in fructification pod; Its branch is extremely rich also stretch, have very powerful pulling force; When run animal touchs branch, branch can be played come over to be twined closely go up in animal body, meanwhile, mature fructification pod is met above dissilient, if shell fragment is same,those fruit in fact that bring thorn are met deeply the skin of penetrate into animal; The animal struggles to be pestered more closely the more, because of,have a few animals this get killed, that only small boar is an unfortunate victim.

帕斯曼经过仔细观察，终于发现了章鱼树的秘密，原来，它的树枝上长满了果实荚，果实荚里都是一些带刺的果实；它的枝条也极富弹性，具有很强的张力；当有奔跑的动物触动枝条时，枝条就会弹过来紧紧缠绕在动物身上，与此同时，上面成熟的果实荚就会爆裂，那些带刺的果实则会如弹片一样深深地刺入动物的皮肤；动物越是挣扎就被缠得越紧，有一些动物因此丧命，那只小野猪就是一个不幸的牺牲者。

The main work accomplished is summarized as follows: 1.Elaborate the main modeling methods for piezoelectric vibrator and the significance and necessity to study the dynamic characteristics of piezoelectric vibrator which emphasize the urgency of this paper. 2.Take the bending deformation induced by piezoelectric ceramic as example, the energy transfer mechanism of electric energy to mechanical energy are analyzed; the motion and force transfer mechanism are analyzed for the longitudinal-bending vibrator. 3.Based on mode assumption and Hamilton principle, the coupling model of piezoelectric vibrator of linear USM is built; moreover, the equivalent circuit model is obtained and a coupling equation represents the relation between electric parameters and mechanical parameters is derived which provides foundation to match the vibrator and driving circuit. 4.Combine the constitutive equation of piezoelectric ceramic with elastic-dynamical equation, geometric equation in force field and the Maxwell equation in electric field and the corresponding boundary condition equation, the FEM control equation for piezoelectric vibrator of USM to solve dynamic electro-mechanical coupling field is established by employing the principle of virtual displacement. The equation lays the foundation to study the non-linear constitutive equation of piezoelectric ceramic driven by high-power. 5.Define the dynamic indexes of characteristic of vibrator and carry out variable parameters simulation by calculating the model parameters and the electric characteristics of vibrator are simulated according to the equivalent circuit model. By numerical experimentation, the working mode of vibration of vibrator and the shock excitation results of the working frequency band which provides the mode frequency to realize bimodal are analyzed. Detailed calculation of the electro-mechanical coupling field parameters is made by programming the FEM control equation.
