In the design and analysis of sequence cipher , we obtain the following results . first , we give the trace representation of primitive sequences and their corresponding highest lever sequences on galois ring by using the trace function theory and the characteristic of lever factorization , and determine the correlation function linear complexity and element distribution of the highest lever sequences of primitive sequences on galois ring gr ( 4 , m ) 在序列密码的设计和分析方面：首先，利用galois环上迹函数理论和本原序列的权位分解特征，给出了本原序列及其最高权位序列的迹表达式，然后利用galois域上二次型理论与指数和理论决定了特征为4的galois环上本原序列的最高权位的相关函数、线性复杂度和元素分布。
The reason was that pma was linear polymer and that the incompatibility of pdms and pma leaded microphase separation . additional , xps analyzed the three kinds of elements in surface and interior of ipn , the results indicated that the content of the elements c , si and 0 were misdistribution and different in surface as well as in interior of ipn . the reason was the poor compatibility of pdms and pma , and found that amount of initiator and the reaction rate effected the distribution 另外，本论文还通过xps电子能谱仪对工pn材料的表层和内层的化学元素c 、 51 、 o进行分析，发现表层与内层中的三种元素的含量并不相同，也没有规律可循，说明在形成ipn结构过程中，由于两相相容性不一致，它们的微运动趋向于两相分离，同时发现引发剂用量和反应速度对元素分布影响较大。
To analyze the distribution of chinese decor industry customers " internal value index and to find the method of brand positioning based on customer internal value , the author apply the " graphics of consumers " internal value " - an new method on analyzing the customer internal value - to chinese decor industry . based on an customer survey and much desk research and the case analysis , the author deeply explain the consuming habit of decor industry customers , analyze the distribution of decor industry customer internal value index and the characteristic of customer internal value in subdivided decor industry market , and analyze the strong points and weak points in brand positioning of famous decor brand " ikea " 本文是对消费者价值分布和基于消费者价值的品牌定位的研究，旨在通过借鉴著名国际市场研究公司罗兰?贝格战略咨询公司所开发出的“消费者价值分布图解法” ，并基于对中国上海204份随机抽取的样本所进行的问卷调查，深入分析中国家居市场消费者的价值元素分布、消费者需求的变化趋势、细分市场的消费者特征，并探讨国际著名家居品牌- - - - - -宜家家居- - - - - -在中国的品牌定位以及其品牌定位与其目标消费者价值分布的联系。
This important tectonic zone parallel to the isotopic geochemical steep zone , which represented a suture line between the yangtze and cathaysian blocks . the geochemical evidence of the jianshui volcanic rocks from the sw part of shizong - mile zone shows that their lithologic types are tholeiites with the comparative flat ree patterns and enrichment in th , depletion slightly in nb , ta , and flat hfse . thus , they may be formed in a back - arc basin with the characteristics between morb and island - a 该构造带西南段的建水火山岩地球化学特征研究表明，该火山岩为拉斑玄武岩，具有较平坦的稀土分配型式， th较富集， nb 、 ta轻微亏损，高场强元素分布较平坦，具有介于岛弧和morb之间的地球化学特征，可能形成于弧后盆地环境。
It is researched that the influence on the tube lifetime of the metallographic structure and the alloy element by testing the superheater and reheater tube which is made of 12cr2mowvtib steel . the metallographic change and the distribution of alloy elements after the tube has run in the high temperature condition for longtime is more believable and franker to evaluate the tubes remain life time 然后，通过试验研究了过热器和再热器管12cr2mowvtib钢材的金相组织、合金元素对管道寿命的影响，分析了管材在高温长期运行后金相组织和合金元素分布的变化情况，对管材寿命进行定性评估。
