The equations of motion for the nonlinear nonplanar flexible cantilever are derived by using the generalized Hamiltons principle. Then, the Galerkin procedure and the method of multiple scales are used to give the perturbation analysis of the system and the average equations. The three resonant cases are considered in this dissertation.

The bifurcation and chaos behavior of impact and rubbing fault rotor system caused by the parameters of nonlinear rigidity, rotor rotating speed, eccentric mass is analyzed, in the numerical value analysis method. The bifurcation diagrams, maximum Lyapunov exponent diagrams, Poincaré maps, phase plane portraits, trajectories of journal center, time-history curve, amplitude spectra diagrams of the rotor motion are used. The convert and evolution course of periodical response, quasi-periodical response, double-periodical bifurcation, chaos of the system response is analyzed.(3). It is deduced that the general differential equation of bending-torsional-pendular coupling vibration about rotor with the gyroscopic moment. On the basis of this equation, the general differential equations of coupled bending, torsional and pendular nonlinear vibration about rotor with unbalance character and rubbing character are deduced.

objective trimetazidine has shown anti-ischemic properties to improve exercise tolerance without haemodynamic effects and direct cyto protective effect on the myocardium.however,it is not clear whether trimetazidine has beneficially effect on severe ischemic cardiomyopathy.methods 19patients（68±9）years with postnecrotic left ventricular dysfunction（ejection fraction31.7%±5.4%）were studied to examine the benefit of adding60mg a day of trimetazidine for3months to the classical therapy.the assessment included clinical evaluation,electrocardiography and echocardiography.results after adding60mg a day of trimetazidine for3months,attack of angina was relieved and dyspnea was improved（p.05）.but heart rate,systolic blood pressure,rate pressure product,ejection fraction,left ventricular volume and global wall motion index were not changed.conclusion trimetazidine seems to improve clinical status while can not change oxygen supply-to-demand ratio without adverse effects in patients on severe ischemic carˉdiomyopathy.

目的 曲美他嗪是一种新型的抗心肌缺血的药物，能够改善患者的运动耐量和心肌的直接保护作用同时并没有血流动力学效应。但目前对于严重缺血性心肌病患者的临床治疗价值还需要进一步观察。方法 19例（68±9）岁确诊为缺血性心肌病（左心室射血分数0%）的患者在常规治疗的基础上加用每日60mg曲美他嗪治疗3个月，随诊观察患者临床情况以及超声心动图指标的变化。结果 19例患者均可耐受在常规治疗基础上加用每日60mg曲美他嗪的治疗，随诊发现患者心绞痛发作明显减少，运动耐量明显改善。同时患者心率、收缩压、心率血压乘积、左心室射血分数、左心室容量以及整体室壁运动指数无明显改变。结论缺血性心肌病的患者在常规治疗基础上加用曲美他嗪是安全的，同时其能明显改善患者的临床状态，而这种作用并不改变心肌氧的供求比值。
