Sequences analysis revealsthat these 54 strains have as high as a 99% similarity in 16S rRNA gene level. Allthese 54 strains could be classified into six subgroups according to six differentregions on full-length 16S rRNA gene. Even if the regional differences are not evidentto distinguish B. thuringiensis from B. cereus, however the data of the 16S rRNA genesequences will serve to broaden the database for Bacillus, and provide someinformation for the classification of genus of Bacillus. Additionally, seven B.

本研究利用通用引物，对54株苏云金芽胞杆菌和蜡状芽胞杆菌的16S rRNA基因进行测序，并对所得到的序列进行简单的分析，发现苏云金芽胞杆菌和蜡状芽胞杆菌的16S rRNA基因的相似性很大，大约为99％，在其全长含有6个区域的不同，根据这6个区域将Bt和Bc分成6个亚群，而Bt和Bc在不同亚群之间交替存在，说明16S rRNA基因上的差异不足以区分Bt和Bc。

为此，本文提出一种基于多级分类神经网络级联的人脸判别方法，通过把基于不同颜色分量的多级神经网络级联起来，并利用不同颜色分量由于来源、定义、算法的不同而体现出来的不同特性，以不同的颜色分量图象作为各级神经网络的分类特征，有效提高了人脸判别的正确率。

On the basis of theoretical analysis of target diffusion in range-velocity resolution cell, the array signal covariance matrix and noise covariance matrix are estimated from some different cells respectively. The processing results from experimental data in onshore HFSWR with Minimum Variance Distortionless Respose, MUltiple SIgnal Classification and pre-whiten MUSIC respectively show that super-resolution methods can provide better resolution than CBF.

鉴于 HFSWR 工作波长较长、常规波束形成角分辨力较差的缺点，基于目标在距离—多普勒平面分布的理论分析，本文利用相邻距离、多普勒频率单元信号估计阵列协方差阵，并分别利用 MVDR 、 MUSIC 、预白化 MUSIC 方法进行超分辩处理，实测的合作飞机目标数据处理结果表明超分辩方法能明显提高阵列角度分辨力。

Position parameters were obtained from the simulation with the model of towed array.Based on the theory of radiated noise forming, the launch noise was simulated according to test condition in Laboratory,and the result showed the launch impulsion noise obeyed SαS distribution. The simulated noise attenuating in deep sea was analyzed with a sound loss translation model.Minimum variance distortionless response,spatially smoothed MVDR, and beam-space multiple signal classification algorithm were adopted to process the signal, hence the source level, the frequency structure and the location of the launch noise were achieved.

基于试验的实际情况，根据潜艇拖曳阵模型，仿真生成了各水听器阵元与本艇的位置关系；根据噪声源理论模型分析产生雷弹发射模拟噪声，利用SαS分布模拟武器发射冲击噪声，仿真分析模拟噪声在海洋环境中的传播衰减，对阵元信号分别利用最小方差无畸变响应法（MVDR 、空间平滑MVDR以及适应子带的波束域多重信号分类算法进行信号处理，得到发射噪声的声源级、频谱结构和方位。

Part two is about the analysis of theoretical basis for the social assistance legal institutions,which includes their department classification,their analysis of basic concept,their theoretical support and their analysis of value,and so on.The author holds that they regulate the redistributive economic relations requiring state intervenes appropriately and reflected by the actions of social assistance,they reflect and determine the implication and distribution of the redistributive economic relations,meanwhile they reflect and determine the distribution and direction of the benefits of social assistance intervened by state appropriately.Their appearance expresses the legal connection created for the poverty phenomena between state and the poor,so these legal institutions should be classified into the department of social distributive law in economic law which reflect the essence of economic law that state intervenes the economic relations required intervention appropriately.

第二部分是社会救助法律制度的理论基础分析，其中包括社会救助法律制度部门归属辨、社会救助法律制度的基本理念剖析、社会救助法律制度的理论支持以及社会救助法律制度的价值分析等内容，认为社会救助法律制度规制了由社会救助行为所反映出来的这种需要国家适度干预的再分配经济关系，反映并决定了这种再分配经济关系的牵连和分布，同时反映和决定了在国家适度干预下相关社会救助利益的分配和流向，其出现媒介了国家和贫困者之间因为贫困现象而生成的法律关系，这一法律制度归属于经济法部门中的社会分配法律制度子部门，明显地体现着经济法的本质属性——国家对需要干预的经济关系的适度干预。
