Its theory is: evaluate periodical by various methods, and then make the results standardization, select the extreme value of these results as the final score of periodical. The research indicates that it is must been used carefully to calculate weight by combined assessing method; assessing methods based on order can't been used to combine; combined assessing based on extreme value method is propitious to establish harmonious relationship between assessor and assessee.
其原理是,首先选用各种可行的评价方法进行评价,然后将评价结果标准化,将同一期刊不同评价结果的极大值作为该期刊的最终评价结果,取得了较好的效果,研究表明,采用组合评价进行权重计算必须慎重使用;基于秩序的评价方法不能用于组合;基于极值法的组合评价方法有利于建立和谐的评价者与被评价者关系,结果容易得到公认。

We discuss asymptotically best linear unbiased estimators of the Logistic population based on selected order statistics and give the formula of computing the ABLUE, the variance and the covariance of the ABLUE in limit, and properties of the ABLUE, and so on. We give the optimum chosen of spacing which is the ABLUE with maximum asymptotic relative efficiency based on complete sample when selected order statistics number is less than 10, and obtain its maximum asymptotic relative efficiency.

Based on the petrological and geochronological study of metamorphic complexes from the Grove Mountains, the following conclusions are reached.(1)Exsolution texture is widely found in clinopyroxene in mafic granulites. A peak metamorphic temperature of 850 C was obtained from the reintegrated compositions of exsolved clinopyroxene. The preservation of augite megacrysts suggests a single episode of high-grade metamorphism for the Grove Mountains.(2)The compositional comparison of garnet from pegmatites with that from country rocks demonstrates that garnet in pegmatites is of xenocryst origin, and late amphibolite facies metamorphism does not occur in this area.(3)The Pan-African charnockite and post-tectonic sheet-like granite were first recognized in East Antarctica. Their occurrences suggest a collisional orogeny during the Pan-African time.(4)The SHRIMP U-Pb zircon dating on various rock types indicates that the major metamorphism in the Grove Mountains occurs at c. 550 Ma, and the tectonothermal evolution terminated at c. 500 Ma. The Grenvillian granulite facies metamorphism did not develop in the studied area.(5)The Prydz belt, the second Pan-African suture within the Gondwana suppercontinent, was further comfirmed based on this study. The Gondwana suppercontinent was not formed by the simply juxtaposition of East and West Gondwana, but by the collision of several blocks during the Pan-African time.
本项目通过格罗夫山地区高级变质杂岩的变质岩石学和同位素年代学研究,获得如下重要认识:(1)发现辉石出溶结构,由此获得峰期变质温度为850 C,并根据火成普通辉石的识别确定该区只存在单相麻粒岩相变质;(2)通过伟晶岩中石榴石斑晶与围岩中石榴石的对比研究提出了石榴石的捕虏晶成因,进而确定该区不存在晚期角闪岩相变质作用;(3)在东南极首次识别出泛非期紫苏花岗岩和后构造层状花岗岩,为泛非构造热事件的碰撞造山成因提供了重要佐证;(4)对不同岩石类型的锆石SHRIMP定年精确地限定了格罗夫山地区主期变质作用发生于泛非期,~550 Ma,热事件结束于~500 Ma,年代学数据没有揭示在该区存在格林威尔期麻粒岩相变质作用的迹象;(5)进一步确认了东南极内部普里兹带的存在,它属于冈瓦纳超大陆内部的第二条泛非期缝合带,据此认为冈瓦纳超大陆并不是由东、西冈瓦纳陆块的简单拼合而成,而是多个不同块体拼合的结果。

The common method, that all strong-correlation terms of the model are eliminated, can bring the loss in the engineering application, so the new method is proposed that the identified model reserves some correlation. The augmented matrix A is constructed by the outputΔW and the matrix S. The"determinating order based on ratio of determinant"is brought out to screen the strong-correlation terms in the structure identification. The latent root estimation is improved in screening the eigenvalues and eigenvectors. Thus the estimation precision is improved greatly.The consistence check of guidance instrument error coefficients of flight test and ground test is the purpose of flight experiment. The causes of inconsistency of the two models are analyzed. The hypothesis test of linear regression model based on F statistics is proposed to check the consistence.Finally, the instability of error coefficients is probably caused by the change of the flight environments, therefore, the relation between the error coefficients and flight environment is analyzed. The approach is presented to identify SINS guidance instrument error models and compensate the error in the segmented sections corresponding to the change of vertical acceleration of aircraft.
在结构辨识中,常用的方法由于将模型中的强相关项全部剔除而给工程应用带来损失,因此,本文提出了新的有益思想,即在保留一定相关性的基础上进行辨识:将输出向量ΔW与环境函数矩阵S构成增广矩阵A,然后采用"比定阶行列式"来剔除相关向量的方法,这样既可以尽可能多地保留了对落点影响大的强相关参数,又可以对落点影响小的强相关参数给予剔除;在参数估计中,改进了特征根估计中特征根和特征向量的筛选方法,提出"近零"准则,从而大大提高了参数估计的精度;再者,鉴于天地模型"一致性"检验是飞行试验和SINS制导工具误差系数分离的主要目的,因此,本文又深入分析了造成天地模型不一致的原因,提出了采用基于F统计的线性回归模型假设检验方法来进行捷联制导工具误差模型的天地"一致性"检验;最后,鉴于飞行环境剧烈变化可能会对惯性仪表误差系数稳定性带来一定的影响,因此本文深入地分析了SINS制导工具误差系数与外界环境的关系,提出了基于过载变化大小的分段辨识和分段实时补偿的算法。
