Aiming at a class of complex electromechanical systems, such as 4-high or multi-high cold mills and continual mills, we firstly construct mathematical models of every subsystems by means of structural principle modeling method; nextly, get the overall mathematical model of electromechanical drive system by joining together these subsystems'models according to coupling variables and parameters; we finally simplify the overall model according to time-scale principle which can retain main eigenvalues and significant state variables, and obtain a practical mathematical model of complex electromechanical system. By simulating the CM04 temper mill's model constructed by above-mentioned method, we test and verify that the modeling method is effective and practical. The study analyzes and researches the electromechanical coupling facts and acting laws existing in complex electromechanical system.

Methods: The sample consisted143 children which were in early permanent dentition of ClassⅡ,Division 1malocclusion .Pre-and post-treatment study models were assessed using PeerAssessment Rating index. According to the outcome of treatment, thesecases were classified into three types as "worse, no different","improved"and"greatly improved". The cephalometric analysis and Model Analysis werepreformed with pretreatment lateral cephalograms and study models for"improved"and "greatly improved"cases."T"–test was assessed to find out thesignificant difference between the extraction and nonextraction, and the resultsincluding age factor were analyzed by stepwise discriminant analysis.

应用PAR 指数对矫治前后的143 副恒牙早期的安氏Ⅱ类1 分类错牙合患者牙牙合模型进行评估分析，按矫治结果等级分为三类A、变坏或无改善，B、改善，C、极大改善，然后将B、C 两类患者矫治前的头影测量片及模型分析数据按拔牙与未拔牙进行成组t 检验的单因素分析，找出两组间有显著差异的软硬组织和牙牙合模型指标，对这些指标合并年龄因素进行逐步判别分析。

The conditional nature of the distribution over label sequence can depend on non-independent, interacting features of the observation sequence. CRFs offer a solution to the problems in Chinese shallow parsing with hidden Markov models or with maximum entropy Markov models. First, as HMMs are generative, it is hard to employ overlapping features and nonindependent features of the inputs such as surrounding words.

通过单个状态将增大的或减小的概率和传递到它们的后继状态，使得这个单一的分布不需要对每个状态进行归一化，整个状态序列可以一起描述，从而克服了HMMs和 MEMMs的标记偏差（1abel bias）问题，而标记偏差的问题在汉语浅层分析中是个严重的问题。

Constant value of vena contracta coefficient has been employed in the well-used quasi-steady models for computing the nonlinear acoustic impedance of the orifice. However, this nonrealistic assumption degrades the accuracy of the theoretical models.

This paper is mainly comprised of two components:preparation of models of rats suffering from deficiency of spleen Yang;comparison of the pharmacodynamics impacts of different Lizhong Pills formulations made up by dried ginger or its different components in Lizhong Pills to the different groups of the models.1 Establish the model of deficiency of spleen YANG induced by " cypsum fibrosum and anemarrhenae " with complex factors1.1 ObjectivesWith using heat-clearing and fire-purging drug cypsum fibrosum and anemarrhenae,insteading of the common usage of rhubarb and folium sennae,accompanied with irregular diet and overstrained,the model of deficiency of spleen-YANG is to be established,which is much close to the pathopoiesis theory of " frigidity and chilly damaging yang,irregular diet injuring qi,overstrain impairing the spleen" in TCM.1.2 MethodsModel rats is fully fed every other day,given the molding drug of cypsum fibrosum -anemarrhenae(concentration 4:1) with 3 different frequency,and arranged to swim everyday in 25℃water until exhausted(performing as spitting bubble 3 times continuously or sinking unable to float by itself).

全文共分为脾阳虚模型的制备和干姜及其成分对理中丸药效学影响的比较两大部分。1&石膏-知母&复合法脾阳虚模型的制备1.1目的以清热泻火药石膏-知母代替常用的大黄、番泻叶类苦寒泻下药，并结合饥饱失常、劳倦过度的方法进行造模，以期建立更符合中医&寒凉伤阳、饥饱伤气和劳倦伤脾&致病思路的中医脾阳虚证候模型。1.2方法模型动物隔日足量喂食，每日在25℃水中游泳，直至大鼠连续三次吐泡下沉，或沉入水底，3秒内不能自行浮出水面，并以三种不同给药频率灌胃给予石膏一知母煎液，比较石膏-知母不同给药方法对制备脾阳虚模型的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
