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。

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。
