The coking and deactivation process of benzene and ethylene alkylation reaction over AB-97 zeolite has been studied systematically. The results of acceleration deactivation reaction indicate that deactivation process go through three phases, high level activity stability period, activity decline period and low level activity stability period. The mechanism of this phenomenon was analyzed by the way of the experiment research of pore structure and acid quality of coked zeolite. It is concluded that reducing the strong acid active centers and crystal outer-surface active centers are benefit to improve the activity stability of zeolite.

在AB-97型分子筛催化剂上对苯/乙烯烷基化制乙苯反应体系的结焦失活历程系统实验研究，催速失活实验结果表明失活历程经历高水平活性稳定期，活性衰退期和低水平活性稳定期三个阶段，并通过对失活催化剂的孔结构及酸性质的实验研究，对这一现象进行了机理分析，认为催化剂改性研究中采用降低强酸活性位和晶粒表面活性位这两种手段都有利于改善催化剂的活性稳定性。

Basing himself mainly on the materials in Zuozhuan, the author has rejected the previous scholars" opinion that the faith in Tian had been shaken and spoiled in this time period as the product of garbing according to their instant need, he states that, they had not given up the worship of the god of Tian, that the declaration of satisfying the god of Tian with moral deeds gradually became the prevailing ideology and greatly influenced the later generations including the Spring and Autumn Period, and that owing to the domination of Tian over people"s life, undoubtedly, some people or groups who were conceived wrong received penalties from the god of Tian, the will of which became the ultimate ground of crime in this period.

由于人们相信天主宰人间的一切，奖善罚恶，人们只有通过德行才能获得天的眷顾，所以，人们相信，那些严重违反德之人或集团理所当然地应该受到天之处罚。换言之，多数人对此确信无疑的时候，天意就成为刑罚的根据。为了避免以推理代替论证，本文利用《左传》中的史料进行了论证。我们在讨论犯罪以及刑罚根据的时候，犯罪及受到刑罚处罚者往往是卑者。德，根据前面的论述，是相互的。比如，父慈子孝，君信臣共。

The research method is combining historic happening with scientific research.This paper is composed of seven chapters. The preface explains briefly the reason of choosing this topic and its significance, as well as the existent research situation in the academic circle.The first chapter presents the subjective and objective historical condition of the formation and development of his view about population quality in four aspects.The second chapter gives a full play to its evolution: it gestates and germinates before the failure of the revolution in 1911, takes shape and develops in the period of Base Area. The following period after the founding of People's Republic of China is its mature time. This view also experiences twisty developments in China's exploring period of socialism.The third part focuses on its major connotations, including Mao's narration on the connotation of Population quality, his analysis of contradiction between population quality and Chinese revolution and construction and of their significance, and the way to enhance Chinese population quality.The fourth chapter makes analyses of philosophical support of Mao's view from three "adherences": adherence to basic principle of seeking truth from facts;adherence to the common acknowledged fact that the people is the main part of history;adherence to the dialectical relation between being and consciousness.

Testimony to this is the discovery, in excavations, of coins of the Han period but the outstanding monument to this turbulent period must undoubtedly be the fine brick-built tomb uncovered at Lei Cheng Uk in 1955 with its array of typical Han tomb furniture, dateable from the early to middle Eastern Han period.

上述情形，可从在本港发掘到汉代的钱币得到证明。但这动荡时期的显著遗迹，当是一九五五年在李郑屋发现的完整砖墓。这座古墓陈放？典型汉代冥器，可推定为东汉初期至中期的古迹。

Transfer period from Atlantic to Pacific leading by heavy and chemistry industry, the landscape of Maritime Industrial Development Areas is the sign of this period. Following the taking-off of Asia-Pacific region, special with Gaige Kaifang in China, show the coming period of Pacific, leading by multi-economies.(2) Coastal zone in China's lies in the core areas of the world economic periphery. The stage of economic growth just is taking-off, and different littoral zone with the different developing levels.

通过对世界经济重心在各主导海域临海地带时空演变规律的系统性的总结，研究中国临海地带在外向型经济引导下的产业结构转型以及空间结构演化机制和趋势，得出如下要点：(1)世界临海地带经济发展经历了以商贸为主导的地中海时期、以轻纺工业为主导的大西洋时期、以重化工集聚为特征的临海工业开发区景观标志着经济重心从大西洋向太平洋转移，而亚太地区经济腾飞，特别是中国的改革开放预示着以经济多元化为主导的太平洋时代的来临。

In addition,there were three sub-assemblages ploted out in the Atlantic period,Sub-Boreal period and Sub-Atlantic period,which reflected the less vibration of the large-scale climatic change.

对鹤鸣孔的大西洋期、亚北方期和亚大西洋期各划分出了两个孢粉组合亚带，反应了大气候环境下气候的次一级波动。

Through the analysis and contrast between HM core and Dh core, combined with the data of AMS14C, six pollen assemblages were ploted Out. At the mean time, six stages about the vegetation change and climate fluctuation were rebuild. In addition, there were three sub-assemblages ploted out in the Atlantic period, Sub-Boreal period and Sub-Atlantic period, which reflected the less vibration of the large-scale climatic change. Pollen assemblage dominated by Concentricystes in the hard and green clay of late Pleistocene can make it sure that the hard green clay layer was formed by water.

Pottery sherds excavated from the eastern moat were from Longshan Period. Area of the huge moat was very close to the Longshan cultural layer and bigger than the settlements from other periods. Thus, one can see that the moat has been used and constructed during the Longshan period. The moat was filled and abandoned during the Elitou period.

东壕沟沟内主体堆积所出陶片皆属龙山时期，而且大型环壕的范围与该遗址龙山时期地表遗存的分布范围最接近，而远大於其他各时期聚落的范围，由此可断定环壕当在龙山期修建和使用，到二里头期以后被填满、废弃。
