Worn surface morphology was examined with scanning electron microscopy, and wear volume was measured with a Talysurf 5P-120 topographer. Results show that CNTs, in mass concentration of 0.01%~0.1%, can greatly improve the antiwear ability of lubricating oil. With addition of CNTs, the maximum reduction of wear rate is about 57%, and scratches on the worn surfaces become slighter and more uniform. The maximum decrease of friction coefficient is about 15% with 0.025% CNTs additive at the load of 300 N. The antiwear mechanism has been discussed.

结果表明：碳纳米管作为润滑油添加剂表现出优良的抗磨性能，在质量分数仅为0.0125%～0.1000%时，润滑油的抗磨性能显著提高；在质量分数约为0.0500%时其抗磨效果最佳，磨损率降低幅值达57%；在较高载荷下，添加0.0250%的碳纳米管能够使其摩擦系数减小约15%，但随着碳纳米管质量分数的增加，摩擦系数迅速提高；含碳纳米管润滑油的磨斑表面平整，划痕较细且分布均匀。

So this part will propose a new method based on the EMTDC to analyze the torsional oscillation problem. Since the EMTDC only has the 7 masses shaft model, use the user Module to develop a detailed shaft model.

由于EMTDC现有的轴系多质量块模型最多只能考虑7个质量块，所以基于模态转换与模态降阶的思想利用EMTDC自定义模块重新开发轴系的多质量块模型，使得能对轴系各截面进行考核分析。

objective to study the correlation among psychosomatic health factors,depression,anxiety and sleep status in college students,to analyze influence factors in sleep status.methods with questionnaire opened in-vestigation,200college students were evaluated using cornell medical index,self-rating depression,self-rating anxiety scaleand pittsburgh sleep quality index.stepwise regression analysis was used.re-sults total score of sds was35.55±7.8,and sas was0.48±0.9.each score of cmi was higher than normal range,the highest was digestion system,next was respiration system,then,fatigue,eyes and ears,anxiety,sensitivity,tension,maladjustment in turn.total average score of psqi was6.32±3.6,ordinary sleep were115cases（57.5%）,good and bad sleep were42（21%）and43（21.5%）cases respectively.influence factors in total score of psqi were sas,cmi,respiration system,anxiety,past healthy,digestion system,fatigue,sensitivity,sds and malad-justment in turn,using stepwise regression analysis,total score of psqi as dependent variable,each factor score of cmi,total score of sds and sas as independent variables.conclusion problems of psychosomatic health,anxiety and depression could both lead to sleep disorder.

目的 研究在校大学生心身健康因素及抑郁焦虑等与睡眠状况的相关性，并对影响睡眠状况的有关因素进行分析。方法采用问卷式的开放性研究，对在校的200名大学生进行康奈尔心身健康问卷、自评抑郁量表、焦虑自评量表和匹兹堡睡眠质量量表的测定，采用逐步回归分析方法。结果 sds总分为35.55±7.8、sas总分为0.48±0.9，cmi评分：消化系统最为严重评分为2.52，其次为呼吸系统、疲劳感、眼和耳、焦虑、敏感、紧张、不适应等，评分均高于正常常模。psqi总均分为6.32±3.6，一般睡眠有115例占57.5%，睡眠质量较好42例占21.0%，睡眠质量较差43例占21.5%。评估对睡眠状况的影响程度，以psqi总分为因变量，选择cmi各因子分和sds、sas总分作为自变量，进行多因素逐步回归分析，进入方程的因素依据标准化偏回归系数，影响psqi总分的因素依次为sas总分、cmi总分、呼吸系统、焦虑、既往健康、消化系统、疲劳感、敏感、sds总分、不适应（f=226.8；p.01；r=0.73）。结论心身健康问题和焦虑抑郁可导致睡眠障碍。
