The simulation outcome demonstrates that various control measures after April 20,2003 in Beijing and the public holidays starting from May lst to May 5th have a significant impact on containing the epidemic situation. The most dangerous days, around April 27, when the number of uncontrolled SARS patients in the society reached at its peak, can also be calculated. The SARS infectiousness number newly reported in Beijing has been at a low level since May 20. But simulation experiments describe that it may fluctuate with import of SARS infectiousness from outside Beijing, weakening of quarantine, more social activities, and so on.

同时应用动力学模型，对北京的SARS疫情进行分时间段的模拟与SARS实施控制因素影响分析，结果表明，2003—04—20以后一段时间内实行的各种控制措施，以及5月1日—5月5日的长假对于北京SARS疫情的控制是非常有效的；而4月27日左右北京市社会上未得到有效控制的SARS病人数达到高峰，是最危险的时期。5月20日以后，北京的SARS疫情基本保持在低发的平台期，但是如出现较多的外来SARS病例输入，而内部隔离强度又减弱、社交活动增加等情况下，北京SARS疫情可能会有一定程度的波动与反弹。

First, in this essay, the author states the reasonableness and necessity of permitting transfer of mortgaged property, affirms that mortgager will not lose the right of dispose and is entitle to transfer the property freely when the property is under mortgage. And at the same time, the author agrees the theoretical basis of droit de suite and the mortgagee's interests can be protected through the enforcement of the recovery right. Second, the author introduces the legislation of droit de suite in several countries with typical civil law legal system and analyses the particular characteristics of these different registrations. Third, the author points out the defects and malpractice of the legislations in our country after analyzing the legislation which state ambiguously the recovery right of mortgage and restricts the transfer of mortgaged property based on the tracing the development of system in respect of transfer of mortgaged property in Chinese legislation on guarantee. Finally, according to the real situation of our country, the author presents some concrete proposals on perfecting the system of transfer of mortgaged property and droit de suite of mortgage to reach the balance between static safety of property rights and dynamical safety of transactions with the reference to successful expericnees of other countries.

本文首先从理论依据出发，论述允许抵押物转让的合理性与必要性，肯定抵押人在抵押期间不丧失对抵押物的处分权，可以自由转让抵押物，同时认为抵押权追及力的存在具有理论基础，通过赋予抵押权以追及效力即可保障抵押物转让关系中抵押权人的利益；其次，简要介绍几个具有典型意义的大陆法系国家关于抵押权追及力的立法状况，分析各国立法的侧重点；再次，结合我国担保立法关于抵押物转让制度的发展轨迹，对我国立法未明确承认抵押权所固有的追及效力，且限制抵押物转让的规定进行剖析，认为存在一定的疏漏和弊端，具有明显的不合理性；最后，根据我国国情，并借鉴国外立法的成功经验，提出完善我国抵押物转让及抵押权追及制度的具体立法建议，以寻求物权的静态安全与交易活动的动态安全的平衡。

The paper is mainly on the process control of NPP management from the view of proprietor, so it is of great pertinence for it involves the process controlling system, checking methods for the schedule, adjustment and optimization as well as various factors and analysis that influence the overall process. Meanwhile, the paper summarizes more practical checking and comparative methods as well as the application of software from the project management instead of discoursing on the adjustment for the original schedule from the angle of confusing network optimization, it is in this unique style that the research is naturally of more practical and appliable significance for the management of process control in nuclear plant.

本文主要从业主方面研究核电站项目管理的进度控制，从扩建工程的进度控制体系，进度计划的检查方法、计划的优化与调整，影响进度的各种原因及分析，并采取的有效措施，因而本文具有鲜明的针对性；本文未从复杂的网络优化的角度去论述对原进度计划进行调整，而是总结了项目管理中应用较多的检查、比较方法及项目管理软件的应用，从而使得本文的研究具有较强的可操作性，和实际应用意义。

The average percent value of G C (49.3%) was less than that of A T (50.7%), there was a bias of the content of G, T in the third codon; The number of transition G-A and T-C were 22, 15 respectively, which were higher than that of transition A-G and C-T, the number of tranversion C-A, T-G is 2 respectively, and other tranversion patterns didnt occur; the probability of transition was higher than that of tranversion , Ts/Tv = 9.5-19, there was the highest number of transition in the third codon. The gamma parameter a of the lst,nd and 3rd codon positions were 0.00572,0.01237 and 1.05239 respectively, they showed that there was adifferent substitution rate at different codon position. Frequences of synonymous codon usage were relatively biased. The average rates of synonymous and nonsynonymous substitution were 0.0787, 0.0011 respectively, there was a significant difference between dS and dN (Z = 4.713, p.01), and the low ratio( CD = 0.0284 .3) of dN/dS ratio impled that there were selective constraints against the nonsynonymous sites in cyt-b gene, The distribution of nonsynonymous codon substitution pattern related to Grantharm distance indicated that the purified selection at 2nd codon positions was more intensive than that at 1st codon positions. The phylogenetic trees supported the view of the double origin of Chinese goose, which means that domestic Chinese goose was derived from Anser cygnoides and domestic European goose, and Yili was derived from Anser anser.

碱基含量分析可知，序列的G C含量(49.3％)＜A T含量(50.7％)，密码子第三位点的G、T含量都有较强的偏倚性；序列间G→A和T→C的转换数(22次和15次)高于A→G和C→T的转换数(10次和9次)，C→A、T→G颠换数均为2次，其余颠换模式均未发生；转换数明显高于颠换数，Ts／Tv=9.5～19，密码子第三位点的转换数最高，呈现了相当强烈的转换偏倚性；密码子第一、二和三位点的gamma分布参数α值分别为0.00572、0.01237和1.05239，表明密码子第一位点的替换速率变异最大，第二位点次之，第三位点的替换速率变异相对较小；编码同一氨基酸的同义密码子并非随机使用，表现出一定程度的使用偏倚性；同义替换速率和非同义替换速率分别为0.0787和0.0011，dS与dN值间的差异极显著(Z=4.713，p＜0.01)，而ω=0.0284，明显小于0.3，表明雁属鹅细胞色素b基因序列经历了中度净化选择作用；单步非同义替换(Sing-step nonsymonymous codon substitution，SSNCS)分布模式与Grantharm距离之间的关系说明密码子的三个位点所受的净化选择强度不同；构建的最大简约树与邻接树拓扑结构一致，支持中国家鹅的双起源学说，即除伊犁鹅外的其它中国鹅品种起源于鸿雁，伊犁鹅和欧洲的郎德鹅、莱茵鹅起源于灰雁。

In order to draw a photorealistic surface, Bidirectional Texture Functions, a 6D texture function which extends Bidirectional Reflectance Distribution Function to include the self-shadowing, self-occlusion and inter-reflection effects, has been mentioned frequently in recent years. Its main drawback is its massive data size. To solve this, Spatial Bidirectional Reflectance Function techniques compress BTFs into reflectance model parameters. However, SBRDF cannot producethe self-shadowing and self-occlusion effects in real-world surface geometry. This work is aimed to this drawback. I find how self-shadowing and self-occlusion affect the surface by additional physical-based analysis. And I rely on two physical phenomena to divide self-shadowing and self-occlusion into two independent effects. First, self-shadowing is view independent. Second, self-occlusion is independent of lighting direction changes. After these analyses, I use SBRDF and additional self-shadowing and self-occlusion I found to render a photorealistic surface as non-compressed BTFs doing.

为了把物体表面呈现的更真实，六维函数BTFs ( Bidirectional Texture Functions)目前已经被使用的相当频繁，但BTFs的资料量实在太大而没办法直接使用，为了解决资料庞大的问题，传统的SBRDF以逼近光反射模型参数，来达到资料压缩的效果，但是SBRDF对於表面的凹凸所产生的阴影及遮蔽，不能达到逼真的呈现，为了改善这个问题，我们选择从物理方面，找出资料中阴影和遮蔽等属於表面几何的资料并去除，使参数更正确，同时利用两个物理现象去区分阴影及遮蔽为两个互不干涉资料，第一是阴影不会因视角不同而改变，第二是遮蔽不因光线方向不同而改变，经过这些分析，我可以利用SBRDF加上附加的阴影及遮蔽两种独立的效应，来达到彷佛跟未压缩过的BTFs一样的真实绘图。
