Simons [30] proved the non-existence theorem for stable integral current in acompact Riemannian submanifold isometrically immersed into a unit sphere andvanishing theorem for homology groups. In 1984, Y. L. Xin [47] generalized theLawson-Simons nonexistence theorem for stable integral current and vanishingtheorem for homology groups to the case of compact submanifolds in Euclideanspace, and gave several important applications.

As a result, there are no specific advantages of processing signals in frequency domain, and we propose to directly process signals in time domain. By this way, it is observed that in time domain the signal signatures can be arranged into groups of orthogonal components, leading to a very natural group-wise symbol recovery scheme. To realize this figure of merit, we propose a GSC-based receiver, which also takes into account the mitigation of channel mismatch effects caused by the channel temporal variation and the imperfect estimation.

因此，吾人提出直接於时域中处理讯号，於时域中，吾人发现讯号特徵矩阵能够被分为数个拥有正交元素的群组，能自然地被用来设计群组式讯号侦测技术，为了实现此特性吾人提出一个GSC接收机，其能同时抑制通道时间变化与通道估计错误所产生之通道偏差效应。

As for the reason, the phenomenon of industrial clusters comes into being owing to aseries of social and cultural factors that lies in the final products such as technologicalclassification, the possibility of product difference, the interconnection of technologicalinnovation, the taciturnity of knowledge, the dynamic changes of the competitiveenvironment of enterprise and the economy of development, the low transportation costof the final products, and the fashion and artistry.

究其原因，产业集群现象的出现是由于多方面因素的综合作用而造成的，其中包括产品存在着技术上的可分性、产品具有差异化机会、技术创新的网络性、知识的缄默性，以及企业竞争环境的动态多变和速度经济性、集群产品的低运输成本并具有时尚性和艺术性等一系列社会文化因素。

主要结论是壳斗目的八个科分为三支，南青冈科是最基部的分支，壳斗科做为核心高等金缕梅类的姐妹群第二个分出，核心高等金缕梅类聚在一起，并进一步分为两个亚支：第一亚支包括桦木科、核果桦科和木麻黄科；另一亚支则由胡桃科、马尾树科和杨梅科组成，杨梅科是胡桃科和马尾树科的姐妹群。

The enzyme linked immunosorbent assayhas been done to detect Avain Leukosis Virus in the albumen from two flocks of chicken and one Marek's disease vaccine. The percent sample positive for ALV in one flock is 11%, the other is 29%.

用酶联免疫吸附试验，对2群鸡的鸡蛋清和1株鸡的马立克氏病疫苗进行检测，发现2群鸡的鸡蛋清中，鸡白血病病毒的阳性率分别是11％和29％，鸡马立克氏病冻干苗隐藏鸡白血病病毒群体特异性抗原的阳性率为100％。

No entire nitrendipine crystals were observed visually in SEM photos. The results of X-ray diffraction and differential scanning calorimetry analysis indicated that the crystalline form of nitrendipine was highly dispersed in microspheres, so as amorphous state. The drug release rate of microspheres could be controlled with adjusting the ratio of solid dispersion carriers and retarding agents formulated. The agitation speed and temperature of the preparation process have distinct effect on micromeritic properties of microspheres. The release profiles of the microspheres were mainly affected by the stirring rate of paddle, the concentration of SDS and pH of dissolution medium. Cooling speed and time, however, have no evident influence on the drug release rate of the microspheres. The dissolution data showed that the mechanism of drug release from microsphers was mainly diffusion-controlled. The incorporation efficiencies of 3 batches sample were exceed 96. 8％, which implied that the current method was suitable for design sustained-release dosage form for poorly water-soluble drug.

在扫描电子显微镜下观察，在微球内外未发现尼群地平的完整结晶，X-射线粉末衍射和差示扫描量热试验结果也显示，尼群地平已经被高度分散在微球中；微球的释药速度可通过调整处方中固体分散体载体和阻滞剂的比例控制；制备温度和搅拌速度对微球的质量影响较大；溶出仪的搅拌速度，释放介质的浓度和pH对微球的释放有较大的影响；制备过程中的冷却速度和冷却时间对微球的释放行为影响不很明显；方程拟合的结果表明缓释微球的释药行为符合扩散机制；测定三批微球样品的包封率均在96.8％以上，表明该法适合于制备难溶性药物的缓释微球。

The SiO2 content of the dike swarms varies from 50.22% to 61.10% and they are basic-intermediate rock series, mainly basic. The Al2O3 content is generally higher than 15% and they are high aluminum basaltic rocks. The lower magnesium index (Mg#=42.77~62.28) and TiO2 content (0.97~2.41%) illuminate that they suffered magnesium-iron minerals' fractional crystallization and that they did not crystallize from original basaltic magma. The values of Na2O/K2O are all above 1, indicating lower K character. Chemically discriminated, these dike swarms are sub-alkaline rock series.

岩墙群的SiO2含量为50.22~61.10%，属于基性和中基性岩类，以基性为主；它们的A12O3含量普遍高于15%，属高铝玄武岩类；具有较低的镁指数（Mg#=42.77~62.28）及TiO2含量（0.97~2.41%），说明它们经历了镁铁质矿物的结晶分异作用，也指示它们不是由原始玄武岩浆结晶；Na2O/K2O都大于1，显示出低钾的特点；岩石化学判别，岩墙群岩石属亚碱性系列。

职是之故，论文共分八章：第一章交代方法；第二章绘测五四知识场及其组成；第三章以五四前期掀起新文化巨浪的《新青年Ⅰ》为对象，理解当时最活跃的新文化份子在经历建立共和及其后乱象后，到底是如何延续辛亥的革命思考；第四章分析国民党群体的《建设》、《星期评论》，以明了他们在三民主义旗帜下的革命观；第五章以研究系的《解放与改造》为分析对象，看这群与进步党或立宪派渊源颇深的知识群体，又是如何理解革命的；第六章则把视线转移至自由派知识份子的《努力周报》，看这群受英美自由思潮、实验主义影响的群体怎样在细部改良的思想驱动下与革命思潮相抗；第七章则分析热烈拥抱革命的马克主义群体的《新青年Ⅱ》、《向导》，以期还原他们的革命理论；第八章则综合此前所得，挑明五四的革命论理形态大致可分为静态革命观与能动革命观两类。
