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.

In this paper,a new variable structure robust model reference adaptive control scheme is proposed,which deals with a class of SISO plants under parameter and unmodelled dynamical uncertainties.It is shown that even with the existence of unmodelled dynamics,the output tracking error will converge to zero in finite time, and the SPRcondition for reference model is not required.

摘 要 讨论了含结构不确定SISO系统的变结构模型参考鲁棒自适应控制问题，提出了一种新的变结构控制方法，使得：1系统在同时含参数及结构不确定性时，跟踪误差仍能在有限时间内收敛到零；2无须假设参考模型为SPR函数。

To solve the nonlinear attitude control problem of a class of spacecrafts, the strongly coupled dynamics model is decomposed into some subsystems and the coupling between the subsystems, unmodelled dynamics and exterior disturbances are regarded as the uncertainty of the system.

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。
