Under poor economic conditions , it is an important problem for the construction of the western culture of how to break down the closed or conservative western culture , and give play to the west local and national culture 在经济基础比较薄弱的条件下，如何打破西部文化的封闭性、保守性，发挥和保持西部地域文化的本土性、民族性，成为促进西部文化建设迫切需要解决的大问题。
Section 3 using the dini derivative and integral inequality ; the stability of delayed neural network is studied . section 4 the case of stability of nonlinear delay neural network under the variable delay is studied , and we have the less conservative result 第四节，研究了非线性时滞神经网络在时滞不确定情况下的稳定性情况，得到保守性较小的结果，其判据为与时滞有关
On our conjecture , gene 3a , a highly conserved sequence , may be the determinant of the virulence of fmdv . changes in 3a have been associated with altered host range . a deletion in 3a has been associated with bovine attenuation of fmdv 我们根据已有资料推测， 3a基因可能是口蹄疫病毒的毒力决定簇，它具有高度保守性，其变异和部分缺失对病毒在牛体内的致弱和宿主嗜性发生改变起重要作用。
The start codon is at 84 - 86bp , the stop codon at 1658 - 1661bp . the homologous comparison of the deduced amino acid sequence with other plant epsp synthase proteins shows the identity to those of b . napus , a . thaliana , tomato , n . labacum respectively are 92 % , 91 % , 80 % , 65 % 同源比较该段序列所编码的氨基酸序列可以发现epsp合成酶有较高的保守性，它与欧洲油菜、拟南芥、西红柿、烟草的同源性分别为920 、 91o 、 80o 、 65o 。
The secondary structures of seed globulins ( i . e . - helix and - sheet ) share many similarities and are highly conserved , which related with specific functions closely ; however obvious differences were observed in variable tertiary structures involved in general functions 种子球蛋白二级结构（如-螺旋和-折叠）存在较大程度的相似性，具有较大的保守性且与蛋白质的特殊功能关系密切；而三级结构之间差异明显，属易变异区，主要与蛋白质的一般功能相关。
In the society of the hakkas country women ' s gender has stronger tradition and conservative , women lack utterance hegemony in public field , women ' s initiative acquisition in private field is directly proportioned to their contribution to families , women ' s self - acception of main identity is stronger 客家乡村妇女的社会性别具有较强的传统性和保守性，妇女缺失公共空间的话语霸权，私领域主动权的获得与其对家庭的贡献成正比，妇女主体身份的自我认同性较强。
Firstly , considering the uncertainty as full - block matrix whose h norm is bounded , a robust controller is designed and robust stability of the system is analyzed using method . secondly , given the structure information of the uncertainty , synthesis is adopted to design a robust - performance controller to eliminate conserveness in h design . finally , combining the individual advantage of h2 control and h control , a mixed h2 / h optimal controller is designed based on linear matrix inequality which makes the system have good time - domain lqr performance as well as robust stability 首先，将未建模不确定性看成是范数有界的满块矩阵，设计了h _鲁棒控制器并用方法分析了系统的鲁棒稳定性；其次，考虑未建模不确定性的结构信息，利用综合设计了鲁棒性能控制器，克服了h _控制理论设计时的保守性；最后，结合h _ 2控制和h _控制各自的优势，基于线性矩阵不等式( lmi )设计了h _ 2 h _混合最优控制器，使得系统既具有良好的时域lqr性能又具有较强的鲁棒稳定性。
It was suggested that eric - pcr could substitute for rapd in research related to the genetic identification and genetic diversity in auricularia and other edible and medicinal fungi : 2 to a certain extent , genetic differences among auricularia strains tested in this study did not have necessary relativity with their geographical origins respectively ; 3 in this study , genetic diversity in a . polytricha was higher than that in a . auricula : 4 in this study , a . fuscosuccinea had a higher homology to a . auricula than to a . polytricha ; 5 morphological characteristics validated the results from eric - pcr and provided a potential explanation for the higher similarity coefficient between a . auricular and a . fuscosuccinea ; 6 southern hybridization was employed by choosing a strain from a . auricula as a probe which hybridized with a . auricula and a . fuscosuccinea except a . polytricha , further confirming the veracity of the results from eric - pcr ; 7 in this study , isozyme analysis could not cluster the 7 strains from three auricularia species to different groups efficiently ; 8 2 strains from two auricularia species revealed high conservative degree and the restriction fragment patterns by 4 kinds of restricted enzymes showed no diversity 本研究中，木耳属2个种的2个菌株在its区域表现出较高的保守性， 4种限制型内切酶的酶切图谱没有显示出多态性；增加内切酶种类及供试菌株数量，有可能获得具有多态性的限制性内切酶酶切图谱； 9本实验中， its区域的真菌特异性引物与真核生物通用引物对于扩增效果无较大差异，扩增片段长度均为650bp左右； 10根据形态学实验、 eric - pcr实验以及southern杂交实验的结果分析，紫木木耳属种质资源的遗传鉴定和遗传多样性评价耳极有可能是毛木耳种的一个变种; n .本研究中所用的gutc法是一种适用于木耳属菌株基因组洲a快速提取的方法; 12 .传统的形态学分类法和现代的分子生物学分类法，两者的关系是相辅相成，互为验证
The design methods of robust stabilizing controller and guaranteeing certain robust performance controller for lurie - type delay systems with norm - bounded uncertainties are studied by delay independent method and delay dependent method . in this paper we adopt the delay dependent method for the conservativeness of delay independent method . the main contents are as follows : 1 根据控制器设计与时滞的关系，分为时滞独立鲁棒控制和时滞相关鲁棒控制，考虑到时滞独立鲁棒控制的保守性，本文研究结论给出的是时滞相关的稳定性条件和鲁棒稳定化控制器。
Compared with the published materials abroad , the identity of dna sequence and deduced amino acid sequence reported here was above 90 % . this result hinted that the gene was highly conservation evolution . meanwhile , the discovery of novel gene might be a basis of function research and breeding resistant plant 测序结果表明所克隆的该段dna序列与国外所报道的植物的该段dna的核苷酸序列及氨基酸序列的同源性均达到90以上，提示了该基因在进化上具有一定的保守性，新基因的发现为进一步研究其生物活性及抗性育种打下了基础。
