Based philosophically on the role theory of sociology, especially the Symbolic Interaction Theory, namely Role Play by Miller, Impression Management and Drama-imitating Theory by Erving Goffman, as well as the author's long-time teaching expriences and observation through the method of cross-disciplinary research on the previous foreign and domestic research results, the thesis demonstrates and analyzes pedagogically, psychologically and administratively the main roles of teachers' in teaching and the regulation of their behaviors

从哲学的角度来说，它是以社会学角色理论为基础的，尤其是以象征性相互作用理论为基础，即以米勒角色扮演理论，印象管理法和Erving Goffman戏剧模拟式理论以及作者长期以来的教学经验为基础，同样还有以作者通过对以前国内外的研究成果所做的交叉学科性研究而获得的研究评论为基础，该论文从教育法上，心理学上以及管理学上对教师在教学和行为规范上的主要作用作出了明确的阐述和分析

Suzuki claims that the new unit will propel the front-drive SX4 from 0-62mph in 12.2sec and on to a top speed of 109mph, while returning 53.3mpg on the combined cycle, and producing 139g/km of CO2 emissions.

结果表明，无分散剂时，随着乙醇中水的体积分数的增加，乙醇汽油的分层温度逐渐升高；加入主分散剂可以显著降低乙醇汽油的分层温度，而少量助剂B、C可显著改善主分散剂A1的助溶效果；随着分散剂体积分数的增加，乙醇汽油的分层温度逐渐降低；在乙醇体积分数为10%，乙醇中水的体积分数为4.3%，分散剂的体积分数为2.91%，其组成V(A1)∶V∶V为90∶7.5∶2.5时，乙醇汽油的分层温度可达到-25℃。90号汽油的辛烷值调合后提高到93号，且其T10和T50点均较调合前低。

Much public large-scale architecture in Napoleon Era represents the demands of bourgeoisie who emerged as European Industrial Revolution comes forth. In the past hundreds of years, artisan and handicraftsman follow strictly the scale, size, and fussy baroque decoration details that could not meet demands of urban population and new commercial forms. Therewith, Frenchmen started to build Paris stock exchange in 1808 and completed in 1827. With applied and simple architecture form, the apartments were multi-storey aiming at providing enough space for population; the ground floor was store and residence for upper floors. The exterior was capacious footpath and landscaping. The typical is reform of start which is rudiment of modern city.

拿破仑时期兴建的一系列大型公共建筑，代表了由于欧洲的工业革命所诞生的新兴阶层――资产阶级的使用要求，在此之前的几百年中，手工匠和艺人对古典主义中的比例、尺度，繁琐的巴洛克式装饰细节，敬若神明，一贯照袭，因噎废食，必然不能符合日益膨胀的城市人口及新兴商业形式的使用需求，于是法国人在1808年开始修建巴黎证券交易所，到1827年完工，采取了实用的、简单朴素的建筑装饰形态；以及为解决人口问题而兴建的大量多层住宅公寓，其底层为商店，上部为住宅，外围是宽敞的人行道并种有绿化，典型的功能为出发点的变革，其实是现代城市的雏形。

Only when heat reservoir temperature is higher than critical heat reservoir temperature can the performance of GAX cycle be improved.

得出了GAX循环性能与热源温度之间的变化关系：在蒸发温度为3 ℃、冷却水为32 ℃的条件下， GAX循环系统最低临界热源温度为110 ℃；在蒸发温度为3 ℃时， GAX循环系统最低临界热源温度值随冷却水温度的提高而升高；只有热源温度高于临界温度值时， GAX循环性能系数才能得到提高。

While mammals are characterized by male heterogamety 〔XX female, XY male〕, birds are characterized by female heterogamety〔ZZ male, ZW female〕.

哺乳类的特征是雄性异配子，即XX核型为雌性，XY核型为雄性。而鸟类的特征是雌性异配子，即ZZ核型为雄性，ZW核型为雌性。

Theobserved strain is 10~2 times as local point strain at the same observed stress.This indicates that macroscopical symmetrical rock is quasi-brittle materialwith microcosmic heterogeneousness and its macroscopical mechanicalbehavior is the results of reciprocity and magnification between microcosmiccharacteristic, not simple sum.(4) The degree of irregularity of strain increases with the number of cycle.But degree of irregularity of transverse strain fluctuates larger at the samecycle. Moreover degree of irregularity of transverse strain is larger than that ofaxial strain. This shows that deformation and failure of rock is process ofevolvement of small crack. Small crack evolves from even and out-of-orderstatus to heterogeneous and ordinal status.(5) Ultrasonic speed decreases with the number of cycle. The decreasecourse is such: Firstly, ultrasonic speed fluctuates in a steady scope in somecycles; And then ultrasonic speed quickly decreases to a certain more smallvalue; Afterwards in succedent cycles, ultrasonic speed fluctuates about thevalue. That is to say, ultrasonic speed fluctuates and decreases at intervals ofcycles. In deformation process of rock, quantitative change and qualitativechange of its small crack evolvement carry through crosswise.(6) Strength and modulus of rock decrease with exponential function asscale of specimens increases.

同一表观应力下，局部点应变与表观应变相差可达2个数量级，表明宏观上均匀的岩石是具有细观特征的准脆性材料，其宏观力学行为是细观特征相互作用、放大的综合结果，而不是简单的叠加；(4)岩样轴向应变不均匀程度和横向应变不均匀程度随循环次数的增加渐进增大，但是在同一个循环内，横向应变离散系数随应力的变化波动较大，且同一循环级别下，横向应变不均匀程度大于轴向应变不均匀程度，表明岩石内部微裂纹的演化是岩石变形破坏的本质特征，这一演化表现为微裂纹从均匀无序分布逐渐向非均匀有序发展；(5)随循环次数的增加，所有岩样内部超声波速会出现衰减，衰减过程表现为在某几次循环内超声波速在某一相对范围内波动，然后急剧减小到某一较小值，在随后的循环内，超声波速又会保持在这一较小值附近波动，即超声波速表现为波动和急剧减小间隔形式衰减，表明从宏观看来平稳的岩石变形过程，内部结构演化过程(微裂纹发展及其相互作用)却表现为均匀量变和突发质变不断交叉进行的现象；(6)岩石强度和弹性模量随尺度增大呈指数函数规律减小。

An impossible event has a probability of exactly 0, and a certain event has a probability of 1, but the converses are not always true: probability 0 events are not always impossible, nor probability 1 events certain.

一个'不可能'事件其机率值为0，而'确定'事件其机率值则为1。但反推并不成立，也就是说机率值为0的事件不表示它就是一个'不可能'事件，同理，机率值为1的事件不表示它就一定发生。

The median time spent on the entilator was three days (interquartile range two to six days) among patients who did not deelop pneumonia, and 11 days (interquartile range six to 19 days) among patients who deeloped entilator-associated pneumonia.
