The static model of torsion joint is based on that of bending joint. The effects of structure parameters inside air pressure, initial angle, rube average radius, rube shell thickness on the turning angle are analyzed and the following conclusions are drawn: the relationship between the angle of torsion joint and the inside air pressure is basically linear, the angle of torsion joint increases with the initial angle and rube average radius, the angle of torsion joint decreases while the rube shell thickness increases. The kinetic equation is built for torsion joint. Simulating experiment implies that the time of inflating and deflating process is extremely shorter than that of kinetic process. So the pneumatic process can be ignored in actual system design and control. The factors that affect the dynamic features of torsion joint, such as shell thickness of rubber tube, average radius, initial angle, connector's outlet area, moment of inertia and viscous damping coefficient, are analyzed and the following conclusions are drawn: the change of rube shell thickness has no effects on the dynamic process of FPA inside air pressure while greatly affects the turning angle of torsion joint; when the rube shell thickness is small, the torsion joint has a bigger turning angle, no overshoot and long risetime, when the shell thickness is big, the turning angle of torsion joint is small, but has high response speed, overshoot and low shock; when the rube average radius increases, the turning angle of torsion joint increases and the overshoot increases too; when the initial angle of torsion joint is big, the turning joint is big, the overshoot is small and shock is low, but the risetime is big; the connector's outlet area affects the dynamic process of FPA inside air pressure greatly, but has no effects on the dynamic process of turning angle; moment of inertia and viscous damping coefficient have no effects on the dynamic process of FPA inside air pressure, but affect the dynamic process of turning angle greatly.
在弯曲关节模型推导的基础上,建立扭转关节的静态模型,并分析了扭转关节内腔压力,初始转角,橡胶管平均半径,橡胶管壁厚等参数对关节转角的影响,得出扭转关节的转动角度与充入FPA内腔的压缩气体压力之间基本呈线性关系,扭转关节的转角随初始角度和橡胶管平均半径的增大而增大,扭转关节的转角随橡胶管壁厚的增大而减小的结论;建立了扭转关节的动力学方程,仿真实验表明FPA的充放气过程与扭转关节的动力学过程相比时间极短,在实际系统设计和控制过程中可以忽略不计;分析讨论橡胶管壁厚,平均半径,初始角度,气体节流口面积,转动惯量,粘性阻尼系数等因素对扭转关节动态特性的影响,得出橡胶管初始壁厚的变化对扭转关节FPA内腔压力的动态响应几乎没有影响而对关节转角的响应曲线影响比较明显,壁厚较小时,关节可以得到较大的转角,并且转角的响应曲线没有超调,但上升时间长,壁厚较大时,关节转角变小,响应加快,但是有超调和轻微振荡现象,橡胶管平均半径越大,得到的关节转角越大,但是转角响应的超调量也随之增大,FPA的初始角度越大,关节的转角越大,并且超调量减小,振荡减弱,但是上升时间增大,管接头出口面积的大小对关节FPA内腔压力的建立过程影响较大,但对关节转角的动态响应几乎没有影响,转动惯量和粘性阻尼系数对FPA内腔压力的动态过程几乎没有影响而对扭转关节转角有较大影响等结论。

Three kinds of BCRC No.51534, 10322 and 10675 would be selected and acted as an experimental sample of Escherichia coli. Results shows that Escherichia coli of No.51534 will appear better performance because the maximum of open circuit voltage, closed current and power density are 1.01V, 22mA and 1342mW/m2, respectively. Concerning the effect of culture time with respect to different phase type on the electricity performance of MFCs, the time points on the intersection between lag phase and logarithmic phase, the middle of point of stationary phase for growth curve of Escherichia coli would appear a good performance of MFCs. In addition, the BCRC No. 51534 Escherichia coli possessing a better performance of MFCs than others would be suggested and applied to further studying. Comparison with the performance of MFCs with respect to electron mediator under different mole number, result shows that electron mediator of methylene blue with 4.63mM would appear a better electricity performance of MFCs than others. Concerning the different material of proton exchange membrane with PTFE-Nafion, Nafion 211, 212 and 117 with respect to the performance of MFCs, result shows that the Nafion 117 applied in MFCs will have a better performance of MFCs than other cases. Finally, the effect of molar concentration on the performance of MFCs would be expected at the studied cases of 0.4M, 0.2M, 0.1M and 0.05M respectively for cathode oxidant, result shows that a good performance of MFCs will happen at the condition of 0.2M. Those observations will be useful to improvement of MFCs in the further study.

Analysis results on townships and villages general statuses showed township health center and village clinic are the major health care facilities in rural poor areas. The number of staff in 36 THCs and 104 VCs were a little lower than the national average. In township health centers, 59. 9% staff are with primary or without any professional titles and 35. 9% of the total staff have no professional degrees. The average gross value of fixed assets per THC is 186000 yuan, among which special equipment values 41000 yuan. Among professional buildings 43. 3% of total area were dangerous. Only one THC can provide emergent service. 47. 2% THCs be able to diagnose and deal with common emergent stomachache. The provision of health services was lower than average level of national rural areas. Frontier Model analysis showed regression coefficients of total outpatient emergency service, total inpatients, average personnel income, number of total staff, number of doctors and technical index were all larger and positive. It meant that these variables would contribute more to the cost-frontier, and their increase would cause the total health cost rising. So increasing health service provision, improving service quality and functions of health facilities may be the best ways to increase efficiency of these facilities. Also the model showed THC inefficiency eu was 1. 68, which means 40% of the cost wasted. Apart from internal and external factors, residents'health care utilization deficiency and inequity is one of major factors causing inefficiency eu.
