Taking the moments of hip and knee joint as its controlled variables, the simulation of the motion equation shows that: After increasing the joint moment at the cushioning phase, the vertical velocity of the body center of mass distinctively speedup while horizontal velocity fall to some degree. Thus, the resultant velocity remains basically constant, but the result distance of long jump can be increased due to the enlargement of the angle of take-off.

A phase-shifted controlling PWM DC/DC full bridge converter with softswitching is proposed and used to realize a constant current power of20A(5~48V).This full bridge converter utilizes the transformer leakageinductance(or the resonant inductance in series with transformersprimary)and the autoecious capacitance of MOSFET to achieveZVS(Zero-Voltage-Switching),as a result it can decrease the switchingwaste,increase the switching frequency,and diminish the power bulk.

The results indicated that both binary interactive parameters of water/isobutanol system from this work and the parameters of water/ethanol from literature can be used to precdict the liquid-liquid equilibria of water/ethanol/isobutanol. But the parameters of ethanol/isobutanol from the literature were not appropriate for the prediction. Furthermore, the model parameters from 30℃ can can be used to predict the liquid-liquid equilibria under 35 ℃. The model parameters of water/isobutanol are independent on the temperatures, so constant parameters irrelative to temperature can meet prediction accuracy. Othmer-Tobias/Bancroft equation was also used to fit the liquid-liquid data of water/ethanol/isobutanol system, but it didnt possess the performance of predicting the liquid-liquid equilibria.The partition coefficients of dipotassium glycyrrhizinat were determined in the liquid-liquid two-phase system of water/ethanol/isobutanol and corrected by experiential equation.

Furthermore, we used western blot to assay the concentration discrepancy of G0/G1 phase-associate proteins P21, P27, P53, cyclin D1, CDK4, p-Erk 1, p-Erk 2 and p-JNK. We found that P21, P27, P53 have significant elevation during 100μM Saussurea involucrate treatment, while CDK4 and p-JNK remain constant and cyclin D1, p-Erk 1, p-Erk 2 are decreased during the treatment.
