This do not make of regressions toward to positivism,but forming a new ...

这并不构成向实证主义的回归，而正在构成新的实践优位的科学实践哲学研究进路；给出对观察/实验与理论各种复杂关系的一个初步分析，观察/实验的确与理论的关系在不同阶段、有不同的特征和变化，不同品格的观察/实验与理论有不同的关系；不能以一个普遍的命题勾勒它们之间的关系。

The result shows that gravity wave excited by the tropopause forcing can propagate stably to the mesosphere through the stratosphere so that the energy and momentum can be transferred from a region to another. In the propagation, gravity wave undergoes growth, overturning, convection and breaking. The breaking of gravity wave is the important source of convection and smallscale waves, and convective instability and overturn are the character of nonlinear phenomenon.

分析结果表明，从对流层顶激发的重力波能稳定地经平流层传到中层顶，从而将能量和动量从一个区域带到另一个区域；在向上传播过程中，重力波经历了发展、位温翻转、对流直至最终破碎的演变；重力波的破碎是对流和小尺度波动的重要的源，对流不稳定和翻转是非线性现象的一个基本特征。

In addition, many studies of patients with AVN showed plenty of special characteristics,such as age distribution and bone quality.Objective:To study the geometric features of proximal femur for the Chinese AVN population,in order to prove the existence of special characteristic of proximal femur for the disease and then develop an AVN-specialized stem evaluated by a validated finite element analysis.Methods:1.The author investigated the standard X-ray data of 127 cases(179 hips) with definite diagnosis of AVN to provide anatomical references for this disease.At the same time,we conducted a meta-analysis of anatomical studies of normal proximal femur data,including the section of LT+20,LT,LT-20 and CFI to identify the potential difference between AVN and normal population.

方法1、通过研究AVN患者标准X线正、侧位片127例(179髋)，获得股骨近端的解剖学数据，利用荟萃分析的方法比较AVN患者股骨近段髓腔特征平面(LT+20，LT，LT-20)及CFI的改变与以往研究数据的差异，并利用创伤性FNF患者资料代替正常人股骨数据进一步比较髓腔前、后、内、外四条曲线段上的差异。2、通过结合现代CAD技术，将内、外、前、后曲线拟合到AVN柄的外形上，选用短柄假体设计，近段设计利用AVN患者骨髓腔CT相对应位置的断面进行修正，设计AVN人工股骨柄。3、计算机三维有限元分析：①使用CAD软件SolidWorks和有限元软件Ansys所建立的髋关节股骨侧假体置换后的三维有限元模型。

From the standardized time series of the intensity index of MPV, the years with values larger than 0.5 are defined as strong years of the monsoon, and the years with values less than-0.5 as weak years. The composite analysis of the anomaly fields of SHF, LHF in these strong and weak years is conducted.

由标准化的湿位涡强度指数距平的年际变化曲线，选择距平值大于0.5的年份为季风爆发的强年，距平值小于-0.5的年份为季风爆发的弱年，对强、弱年东亚及其周边地区的地表潜热通量距平、地表感热通量距平以及海平面气压距平的分布特征进行了合成分析。

When Henry Tudor, who produced a remote claim to the throne, landed at Milford Haven, the treason and desertion that had been a constant feature of the age reasserted itself and Richard found himself almost without supporters.

当亨利都铎，一位要求继承王位的远亲抵达米尔福得港口时，在这个以叛逆和逃跑为时代特征的年代里，理查德发现自己身边几乎没有一个支持者。

After alleging that Rao was trying to cut off support for a discipline of science, Cui compared Rao's efforts to the activities of Trofim Lysenko — the Soviet 'state scientist' who in the 1940s used his close connections to the Soviet leadership to crush scientists who opposed his views.

崔克明就把饶毅比作李森科（译者注：前苏联生物学家和农学家，曾任苏联科学院遗传研究所所长，在其遗传理论中认为后天特征可以被继承），这位前苏联的&国家科学家&在二十世纪四十年代利用其与前苏联领导人的关系打击反对他观点的科学家。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
