Under the instruction of Marxism, the essay systematically reviews and rethinks the history of Western journalism and communication theories narration in the certain field of "media, society and culture" with the throughway of consistency of history and logic. It believes the history can be divided into three historic periods, which are liberalism period, social progress and pragmatism period and cultural critical language period.

本文以马克思主义为指导，运用历史与逻辑一致的思想方法，在特定的&媒介、社会和文化&场域中，系统回顾并反思了自十七世纪以来西方新闻传播理论表述的历史，认为从理论表述的&场域性&来看，它可分为三个大的历史连结点，即自由主义话语时期、社会进步与实用主义话语时期和文化批判话语时期。

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。

According to the content and evolvingcharacteristic of Labour's principle,the long evolution period ofLabour's programme has been divided into four different historical stage,(1)1900-1935,The Formation preiod of Labour's Programme,(2)1935-1951 The riping and utilizing phase,(3)1951-1979 Right-deviation period,(4)The period of compromising with the conservative party's theory.

We performed a simulative test, which confirms that wavelet analysis can separate annual wobble and Chandler wobble. Our results show that this method can be used in astronomical geodynamies effectively. This paper is divided into two parts. The first is about statistic characteristic of polar motion. Polar motion includes secular motion, long period fluctuations, Chandler wobble, annual wobble and high frequency wobble. The secular motion is 3.4mas/year and towards 760W meridian. Long period fluctuations have difference periods in x-axis and y-axis. They are 31.7-year and 24-year in x-axis and 28.5-year and 22.9-year in y-axis. These 2~? decades fluctuations have an amplitude of about 30 mas , and are very nearly linearly polarized, with the observed motion of pole being almost entirely along a line between 360E and 1440W. There is a 55.4-year wobble whose amplitude is 9 mas. The amplitude of the interannual fluctuations is about 4? mas. The amplitude of long period fluctuations decreased after 1970. The annual wobble is a steady wobble. It retrograde wobble is only 1/20 of prograde wobble in amplitude.

本文的工作主要分为两部分：第一部分是通过分析POLE97序列，我们对极移的统计特性有了一个较全面的认识，极移主要包括趋势项、长周期项、Chandler项、周年项和高频项：趋势项的方向是西经76°，速度为每年3.4mas；长周期项中Markowitz 项在X、Y两个方向有不同的周期，它们分别是：X方向的两个周期是31.7年和24 年，Y方向的两个周期为28.5年和22.9年它们叠加在一起是一个线偏振运动，最大振幅约为30mas，偏振方向在西经144°和东经36°之间；极移的长周期波动中还存在一个 55.4年周期的圆周运动，振幅约为9mas；十年尺度变化的振幅在4～6mas之间，在Y 方向十年尺度的成份比较多，它们的周期在X方向和Y方向不是对应的；从七十年代年开始长周期变化的振幅明显降低；周年项是一个振幅稳定的摆动，在X、Y两个方向的振幅略有差别，逆向运动振幅大约为顺向运动振幅的1/20；Chandler摆动的振幅自1900年以来经历了几次较大的变化，其中包括1915年和1955年两次极大值，振幅分别达到0&。25和0&。28，以及1925～1940期间小于0.09的过程，Chandler项在X、Y 两个方向的振幅几乎完全相等，其逆向运动振幅不到顺向运动振幅的1/50。

This study considers the effects of ventilation system using the residential facilities to the transmission mechanism of indoor aerosol in the residential quarantine period space for infective diseases. This study focuses on the effect of the design of ventilation system on the internal flow field and the removal of contaminant pollution. A computational fluid dynamics software-FLUENT 6.2 is employed to simulate the internal airflow field of the residential quarantine period space. The Carbon dioxide (CO2) is adopted as the index of contaminant source. Three layouts of ventilation system are simulated and the airspeed field, the temperature distribution, and the contaminant distribution are analyzed to find the best ventilation system for the residential quarantine period space.

本研究考虑传染性疾病在居家隔离空间使用一般家用环境控制设备时对室内的气悬感染会有何影响，本文主要分析不同通风设计时对居家隔离空间内部气流之影响，并将国内外现有的规范设计方式做一系列之比较以供参考，并以商用套装软体FLUENT6.2分析居家隔离空间内部流场分布情形，模拟中以二氧化碳（CO2）作为病患所呼出含有病菌空气的指标，模拟案例分为三种主要的通风模式，并分析速度、温度与污染物浓度分布情形，以得到最佳的居家隔离空间通风配置方式。

Through difference significance tests and analyses, it finds that (1) man students more possibly form identity achievement, and woman students more possibly form identity foreclosure and identity diffusion; and (2) the difference of self-identity status between man and woman students is associated with various domains; and (3) self-identity status between man and woman students have some similarities that identity exploration has the same importance to both; and (4) grade-one is a period when students face up to more identity crises, and grade-two is key period of identity formation, and grade-three is a developmental period of identity that provides the basis for re-solution of the emergence of new identity crises in grade-four;(5) there is a gradually enhanced direction from lower self-identity statuses to advanced ones from grade-one to grade-three, but there is also a direction that reentry into the identity crisis by grade-four. It indicates that the identity achievement formation does not mean the end of development of self-identity and proves that there is a continuous MAMA cycle in self-identity development; and (6) that students self-identity status mainly is identity moratorium provides some evidence for which there is a Moratorium in student development, and which self-identity formation is not easy; and (7) the development of student self-identity is associated with various domains, what students pay most attention to firstly is vocation, secondly life philosophy, and lower interesting in political and religious domains in ideology; for relational domains, students pay more attention to dating and friendship compared to sex role and recreation domain.

通过差异显著性检验和分析发现：(1)男生更可能形成成就型同一性，女生则更可能形成排他型和弥散型同一性；(2)男女大学生自我同一性的差异与不同的领域相关；(3)男女大学生自我同一性也存在相似性，同一性探索对于男女大学生同样重要；(4)大学一年级是同一性危机面对较多的时期，二年级为同一性形成的关键期，三年级为同一性的发展期，所形成的同一性为四年级所出现新的同一性危机的解决提供了基础；(5)从一年级到三年级存在从低级的自我同一性向高级的自我同一型转变的渐进增强，但到四年级又有重新进入同一性危机的趋势，说明大学生成就型自我同一性的形成并不意味着自我同一性发展的结束，证明了自我同一性发展的MAMA周期持续存在的特点；(6)学生自我同一性状态主要还处于延缓型同一性状态，进一步证明大学生发展心理合法延缓期的存在，以及自我同一性形成不是一件很容易的事情；(7)大学生自我同一性的发展与领域相关，大学生较为关注职业领域，其次为人生观领域，而对政治和信仰领域兴趣较低；另外，大学生对友谊、交往领域较为关注，对性别角色和活动领域关注程度相对较低。

The characters in water-power engineering such as large investment, long construction period and complicated technique make the investment, construction period and quality of the engineering become three main control target in project management.
