In order to verify the model mentioed above, the mathematical simulation of geotemperature field has been carried out. The thrust nappe sheat zones are handled with two ways: 1 they are treated as constant heat sources in terms of q=τμ, that is, the quantity of frictionally generated heat is constant; 2 as heat conduit with high thermal conductivities and with fluid flow in fault zones.

为了进一步检验上述逆冲推覆复合叠加构造模型的可信程度，开展了地温场数值模拟工作，按复合叠加型岩石圈热结构给定各种热物性参数，逆冲推覆剪切带以两种方式处理，一是把它作为定热源按q＝τU，即按摩擦生热量级大小取值；第2种是把它作为热通道处理。

It is a organic hexahydric weak acid. In different acidity, the dissociation degree and the color of reagent solvent were different also. Determined and draw the absorption curve of reagent in varies acidity, and figured out the dissociation constant by Perisic-Janjic method; the complex ratio of the reagent and bismuth was determinated by mole ratio method and continuous variation method; The apparent stability constant of the complex was calculated, the mechanism of dissociation and coordination were discussed.

2，6—二溴4—硝基偶氮氟胂是本实验室合成的测定铋的一个较好的试剂，对其进行了进一步的研究，在用柱层析法对其进行了提纯后，测定了试剂在不同酸华东师范大学硕：l：学位论文摘要度下的吸光度和最大吸收波长，绘制了其吸收曲线，用Perisic一Janjic法计算了试剂的六级离解常数；用摩尔比法和连续变化法测定了试剂与秘形成的配合物的络合比：计算了配合物的表观稳定常数，研究了其离解和配合机理，为筛选高效有机显色剂提供了理论依据。

MethodsUnder the conditions of constant temperature, constant humidity, auto-light and electromagnetic shielding, we gave experimental rats suanzaoren decoction at different doses and adopted chronicity electrode embedment technology to trace the EEG of hypodermal layer of freerunning rats , which rececived electric stimulation.

The mean duration of nymphal development is 60 days in constant long phtopheriod(LD 16:8h) at 30℃.But the mean duration of nymphal development is over 120 days in constant short phtopheriod(LD 12:12h) at 30℃.

在30℃连续长日(LD 16：8h)条件下，小悍蟋若虫60日内全部供试个体完成羽化，而在连续短日(LD12：12h)条件下，小悍蟋若虫120日内仍只有90.7%的个体完成羽化。

The main content includes:B-Site , and substitutions greatly decrease the dielectric losses ofO3 system ceramics under electric field; because of the different characteristics of different ions and the influence of pyrochlore phase created in system, B-Site and ion substitutions increase the dielectric constant of the system, whereas ion substitutions decrease the dielectric constant of the system.

论文的主要研究内容包括：B位，及的取代均大大降低了O3体系陶瓷在电场下的介电损耗；由于各离子特性的不同及体系中生成的焦绿石相的影响，B位，离子的取代使得体系的介电常数上升，离子的取代却使的体系的介电常数有所下降。

It is found that the low dielectric constant inhibits the disproportion of pyrogallic, but it can be settled by increasing the pH or the water content of the reverse microemulsion to obtain a stable generation of the substrate. Then the activity of SOD is determined in such a system and a bell -shaped curve of the activity vs. W〓 is obtained although only subactivity is found. The reasons can be attributed to the low dielectric constant and the attraction of CTA〓.

的介电常数的降低对邻苯三酚的自氧化有抑制作用，因此实验中通过提高CTAB微乳液的表观pH或增大水化度即W〓，最终得到了一定浓度的底物超氧阴离子O〓〓·，保证了SOD活性的测定，并得到了SOD酶活性随含水量变化的&钟形&曲线。

Mr Marvin Cheung Hang: in enterprise development, only constant brand, the product is not intact, because the constant brand needs to readapt the product to market changes.

张建恒：在企业发展中，只有不变的品牌，没有不变的产品，因为不变的品牌需要不断适应市场变化的产品来支撑。

In this paper, the author propose an algorithm, called the least-squares despread respread constant modulus algorithm , combines the information of the spreading signal and the constant modulus property of the transmitted signal in the adaptation of the weight vectors.

本文介绍了利用CDMA信号的恒模特性以及用户已知的扩频码来确定2D Rake接收机的加权系数，使用这样一种综合技术构成的算法称为最小二乘解扩重扩恒模算法。

The constant theme pattern and constant Rheme pattern are employed to ensure the cohesion and the completeness of the information.

These rules reflect some inherent feature of self and nonself, and they are the basic detection criterion of GECISM.

这些规则反映了"自我"和"非我"的内在特征，是GECISM进行"非我"检测的判据。

Until today, the media from China and the outside world still uses the term "Post 89". Regardless to whether it is for commercial gimmick or convenience, everybody still remember "Post 89", a term which carries a strong Cantonese accent.

时至今日，国内外艺术媒体还是在沿用&后八九&这个称谓，不管当初是为了商业噱头还是容易上口好记，反正大家现在是记住了&后八九&这个广东口音很重的词。
