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。

In the modified method, we use orthogonal decomposition so as to delete items which lead to linear dependence of gradient in active constraints. Therefore the Hessian matrix of the DQP subproblem is positive definite.

It is said that the importance of excusing conditions in criminal responsibility is derivative, and it derives from the more fundamental requirement that for criminal responsibility there must be 'moral culpability', which would not exist where the excusing conditions are present On this view the maxim actus non est reus nisimens sit rea refers to a morally evil mind Certainly traces of this view are to be found in scattered observations of English and American judges—in phrases such as 'an evil mind with regard to that which he is doing ',' a bad mind ', or references to acts done not ' merely unguardedly or accidentally , without any evil mind.
有人说,刑事责任中的免责条件的意义是派生性的,而且,其派生于这样一项更基本的要求,即对于刑事责任来说,必须存在"道德上的可责性",而这在出现了免责条件的场合,是不存在的。按照这一观点,"无犯意即无犯罪"的法谚便关涉到一种在道德上邪恶的心理。在英、美法官的分散的评论中——在诸如"与其正在做的事相关的一种邪恶的心理"、"一种不良心理"之类的措辞中,或在对"不只是没有提防地或意外地,没有任何恶意"地实施的行为的提及中——肯定会发现这一观点的迹象。

DNA C-values might be one of important indices in the evaluation of angiospermous invasiveness. To test this viewpoint, we compared DNA 1C-values and basic genome sizes in 3,676 angiosperms. The results suggest that:(1) the two nuclear values vary greatly among different groups, e.g., significantly higher in herbs than in trees, in monocots than in dicots, in perennials than in non-perennials;(2) the two nuclear values both have significant effects on plant invasiveness, especially in herbs, dicots, monocots, perennials, non-perennials, diploids, polyploids, Compositae, and Poaceae, while not significant in trees and Fabaceae.
DNA C值与被子植物入侵性密切相关,为考察应用DNA C值评估被子植物入侵性的可靠性和局限性,我们统计分析了全世界范围内3676种被子植物的DNA 1C值(配子未发生DNA复制时的染色体DNA含量)及基因组大小(单个染色体组的DNA 含量),结果表明:1)DNA 1C值和基因组大小在被子植物不同类群中差异极大,例如在草本植物中显著高于木本植物,单子叶植物显著高于双子叶植物,多年生植物显著高于非多年生植物;2)两项指标都与被子植物入侵性显著负相关,尤其是在草本植物、双子叶植物、单子叶植物、多年生植物、非多年生植物、二倍体、多倍体、菊科和禾本科中,然而在木本植物、豆科植物中其与植物入侵性无显著关系。

In the studying of image segmentation, six crucial technologies havebeen developed successfully. 1 In one dimension histogram of original DRimage of luggage, there remain maximum-value wave crest havingapproximately stationary position, and the first minimum to the left of thewave crest performs excellently to be used to get rid of background of DRimage. 2 Open operation, one type of math morphology, is the right idea toerase luggage disturbance in DR image and at the same time, can be retaininteresting region appropriately. 3 After open operation, there are only a few minimums on image histogram, one of which can be to segment image furtherand achieves satisfying result. 4 Method of histogram analyzing and that oferosion performs well in the re-segmentation of conglutinative region in DRimage. 5 Method of image distance switch can ensure Luggage CT sectionautomatically obtained to have rich suspicious region information. 6 Todecompose structure element of math morphology is a way to save a great dealrunning time for automatically discerning interesting regions algorithm,apparently improving implementation efficiency.

Also, it analyzed the similarity and difference in the relation between income satisfaction and marriage nowadays in China: among those who have been married, the average income satisfaction degree is obviously higher than those who are not married; among them, males have comparatively higher average income satisfaction, which indicates that men obtain more eudemonia factors from marriage. In China, because of the economic and mental difference between the city and the country, the relation between income satisfaction degree and marriage has manifested some diversity, mainly as follows: 1. those who divorced in rural area has the lowest average income satisfaction among all the different marrital statuses; those who divorced in urban area has the intermediate average income satisfaction.
在我国,由于城市和农村在思想上的差异和经济上的差距,收入满足度与婚姻之间的关系呈现一定的差异性,主要表现在:1、农村离婚人士的平均收入满足度在农村各种婚姻状况中处于最低水平;(来源:ABC论70文网www.abclunwen.com)城市离婚人士的平均收入满足度在城市所有婚姻状况中处于中等水平。2、城市再婚人士的平均收入满足度在城市所有婚姻状况中处于最高水平;农村再婚人士的平均收入满足度在农村所有婚姻状况中处于中等水平。3、城市未婚女性的平均收入满足度高于城市未婚男性;农村未婚女性与农村未婚男性的平均收入满足度相同。4、在农村的收入满足度调查问卷中同居一项的样本数为0。

The contributions ofΨp from the pion and the kaon meson, the contribution ofΨB from B meson are not very small, and can not be safely neglected for giving more resonable results of form factors.The B meson wavefunction is a major source of uncertainty in the study of B meson decays. The B→πand B→K transition form factors provide a good platform to determine the possible regions for the two typical phenomenological parametersΛandδ.
但π、K介子波函数中的Ψp和B介子波函数中的ΨB对形状因子的贡献比较大,为了获得更加合理的形状因子的结果,一般不能忽略π、K介子波函数中的Ψp和B介子波函数中的ΨB项的贡献。B介子波函数是B介子衰变中不确定性的一个主要的来源。B→π和B→K跃迁形状因子为确定两个典型的唯象参数Λ和δ提供了一个很好的平台。
