Of course,there is many good thing that I haven't study throughly.

当然还有更多的好东西我还没有研究透彻。

Topological indexes of A , B , C and D were all obtained from the different combination of topological vertex degree. A QSAR equation for this series of compounds was established based on the multi-linear regression method and a new group of autocorrelation topological indexes. The results showed that the biological activity is linearly correlated with the volume and branching size of the quinclorac derivatives. Finally, new herbicide was designed based on all QSAR results.

针对应用经典结构参数和量子化学参数得出的结果不够理想的问题，对点价自相关拓扑指数进行了研究，建立了一组新型的点价自相关拓扑指数A、B、C、D；首次将该指数用于除草剂氯喹酸酯类化合物的定量构效关系研究中，建立了很好的定量构效关系方程，综合分析所有的QSAR结果设计出了潜在的新型除草剂氯喹酸烯丙酯。

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。

the triazole compounds showed good antifungal activity, and it is a good choice for further study.

因此，得到结论：三唑类化合物对真菌感染具有较好的应用情景，值得进一步研究。

Simulating the trophallaxis behavior of the social insects such as bees and ants, a kind of multi-robot systems mission consistency maintenance method was presented.

为了更好地说明任务概念和为基于任务的多移动机器人协作研究奠定基础，提出了一种MTB多移动机器人任务层次结构。

Alright, one final example before I turn you loose to do your own research.

好了，最后一个例子我想谈谈您松散做自己的研究。

Similarly, investigations on the information encoded in finite physical resources will also be helpful for improving the efficiency of state measurement, storage, etc.. This dissertation focuses on some theoretical investigations of quantum state estimation together with discrimination process, and is organized as follows. In the first chapter, we introduce some basic concepts and related background materials, including the theory of quantum operation and unitary group representation, which is helpful for understanding the following content of this dissertation.

在量子密码通信的安全性研究中，测量可获取信息直接关系到窃听能否成功，这实际上对应于量子态的操作和识别过程；在量子通信信道容量、以及态编码的研究中，考察如何利用有限的物理资源标识尽可能多的量子态信息，对提高信息测量、存储的效率都很好的指导意义。
