It was found that La〓 does not affect the binding affinity between calmodulin and Polistes Mastoparan, a known calmodulin binding peptide, neither the conformation of the ternary complex. Excessive amount of La〓 result in the decrease of the binding constant and the disrupted conformation. The binding affinity of La〓 to calmodulin increased in the ternary complex (La〓-CaM-Mas/Mas X), which suggested the coordination between the two global domains. The binding priority between the two global domains is also changed: La〓 more is likely to bind to the C-terminal of calmodulin than to N-terminal, thus facilitates the binding of Mas/Mas X to the C-terminal of calmodulin as the first step of the Mas/Mas X binding.

在以钙调蛋白结合肽—Polistes Mastoparan和Mastoparan X为对象的研究中，我们发现，除非过量，否则La〓的存在不影响钙调蛋白与Mas间的结合常数以及构象；过量的La〓（La〓/CaM摩尔比＞4）将引起钙调蛋白结合功能的下降，同时明显改变金属-钙调蛋白-Mas三元复合物的构象；La〓对Ca〓CaM-Mas的N末端表现高度选择性，显示了在三元复合物中两种离子间的协同效应；在三元体系中，La〓与钙调蛋白的亲和力明显上升，而且亲和力上升的程度因钙调蛋白结合肽的不同而有明显差异，显示了作用的选择性；Mas和MasX的存在改变了La〓在钙调蛋白上的结合顺序，La〓很可能优先与C末端结合，从而使Mas/Mas X首先与C末端结合，该顺序与钙离子相同；La〓的参与使三元复合物在动力学上更加稳定。

The Agent and the MAS architecture were mentioned as the core of M-GIS〓. The standards, criterions and protocols were discussed as the indemnification of M-GIS〓. The third part discussed the Agent, MAS architectures, Agent-Oriented Software Engineering and how to use these theories in M-GIS〓. Based on the clearly cognition of the Agent, MAS and AOSE, the universal Spatial-Info Agent architecture was proposed. This part put the emphasis on applying of the theories about Agent, MAS and AOSE and solving the organization problems of M-GIS〓.

Methods 42 cases mature neonate with MSCT scanning in lung were collected and randomly divided into three groups averagely. The tube current was 50 mAs and 30 mAs for low dose scanning and 200 mAs for routine dose. The CT value of region of interesting and standard deviation were measured in the aorta that region of carina of trachea. And compared the noise, image quality, CT dose index and dose length product between two low-dose scannings and routine dose.

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。

Here is something we often say:'There are many good restaurants in tokyo', in japanese its 'to-kyo ni wa i res-to-ran ga ta-ku-san a ri-mas', translate it back to english, it roughly means 'tokyo in wa good restaurant ga many there-are-inanimate (wa and ga are both particles that follow the pronoun; a-ri-mas is used for inanimated objects or things).

我们常说这句话：&在东京有很多好的餐厅&，用日语说是&to-kyo ni wa i res-to-ran ga ta-ku-san a ri-mas&，将它翻译回英文，它的大致意思是东京在wa好餐馆ga许多都死气沉沉的（wa和ga都是跟在代词后的虚词；a-ri-mas 用于无生命的物体或东西）。

CT images of the 6 UAs showed homogenous and low density in comparison with muscles. Of the 6 UAs, 2 (33%) were lobulate, 4 (67%) were regularly round or oval; 1 (17%) had bone septa, 2 (33%) had root resorption of the neighboring teeth, 3 (50%) had cortical perforation. All UAs showed well-circumscribed margins without soft tissue masses. Three UAs were examined by enhanced studies and showed mild to moderate enhancement of the wall. Of the 5 MAs, 3 (60%) showed low to intermediate density as compared with muscles, 2 (40%) showed homogenous and intermediate density; 3 (60%) had bone septa; 3 (60%) showed root resorption or destruction of the neighboring teeth. All 5 MAs were lobulate with cortical perforation, soft tissue masses, and ill-defined margins. All 3 MA5 examined by enhanced studies showed strong enhancement. CONCLUSIONS: SMAs are usually seen in middle-aged patients.
