We present a SNMP-based topology discovery algorithm using direct connection theorem and simple connection theorem for judging relationship of switches in subnets. In order to in discover the map of network without SNMP, several key problems such as subnet guessing and multi-address routers are discussed in details. And then a topology discovery algorithm based on primitive protocols is presented. We also deeply study some routing protocols such as OSPF and BGP and propose a routing-protocols-based algorithm for topology discovery.

A novel multisensor images fusion algorithm is presented based on lifting quincunx wavelt. First, the lifting quincunx wavelet transform is used to perform a multiscale decomposition of each image. Then, the wavelet coefficients of fused image are constructed using multiple operators according to different fusion rules. Finally, the reconstructed image is obtained through the inverse transform.

After finishing holistic analyses, and considering the specific and relative research on database technique"s application in the remote structural collaborative experiment, this thesis explores and discusses that the proposed database organization scheme can promote the efficiency of the data"s reposting in the Remote Structural Collaborative Experiment, the efficiency of the remote data exchange, and puts out the improving design compared with the NCREE system, that is to use middleware to realize the separation of the experimental process and DBMS and to set up buffer pool to solve the problems, such as to solve network replacement by getting back the experiment.

在完成了整体分析设计之后，针对数据库技术在远程结构协同实验中的应用作了具体的相关研究，探讨了本文提出的数据库组织方案在远程协同实验中可以提高数据入库效率以及远程数据交换效率以及对比NCREE系统设计提出了改进的设计思想，即采用中间件以实现试验进程与DBMS分离以及设立缓冲池以解决网络复位而要恢复试验等问题，并且还研究了在协同实验中分析中的常用数值积分算法，并着重探讨分析了算子分裂算法。

Analysis of performance for five research schemes indicates that the residue is the main structural feature in this peptide system, and residue characterization can be used to describe the entire peptide. This will make characterization simpler and more efficient.

通过对五种表征方案进行对比分析发现，多肽的结构特征主要表现在氨基酸的残基上，可以用残基的矢量描述子来表征整个多肽的结构，从而使表征过程更为简洁有效。

The spores of Cheilolejeunea ventricosa X.L.He were cultured on MS media (without acid and vitamin, pH=6.2, with 1% agar and 1% sucrose). The sporeling development and oil body ontogeny were observed. After a 55-day-long axenic culture, young plants were obtained successfully. Sodium hypochlorite solution was used to sterilize the capsules. Our results revealed that the sterilizing treatment with 0.1% Sodium hypochlorite solution for a period of 5 seconds was optimal. Oil bodies in primary protonemata are nearly homogeneous, but distinctly compound in the leaf cells of the primary leafy shoots.

首次研究了膨叶唇鳞苔的孢子萌发、原丝体和油体发育及配子体发生的过程，结果表明：(1)使用经过改良的MS培养基（不加氨基酸和维生素，pH值为6.2，琼脂和蔗糖浓度均为1%）能在55 d左右的时间利用孢子培养获得植物体；(2)用0.1%的次氯酸钠溶液，消毒5 s是消毒孢子的最佳方案；(3)油体在孢子萌发初期为均一型，到幼叶发生后，成为可见的聚合型，但聚合的程度比野生材料要弱。

In this paper, we design a new surface pressure operator by pressure extrapolation scheme of static equilibrium and the linearity relation between the temperature and pressure.

Study leader, Dr Bjorn Strander, senior consultant in obstetrics and gynaecology at the University of Gothenburg, Sweden, said:"It must be considered a failure of the medical service when women participate in screening, their pre-cancerous lesions are found and they subject themselves to treatment of those lesions, presumably participate in follow-up programmes, and still develop invasive cancer."

瑞典研究员表示，有宫颈癌早期征兆，而接受治疗的妇女在十年之后会患有高危疾病。他们说，癌前期病灶患者应该在至少25年里有规律地经行子宫颈涂片检查。对于那些患有原位癌而接受治疗的英国妇女，最新的指导方案是建议他们每年进行检查，而且检查要持续十年。对于13.3万妇女的研究报告刊登在英国医学期刊上。英国，年龄在25至49的妇女，每三年不时的进行子宫颈癌常规检查，而后直到64岁，每五年检查一次。它可以检测出位于子宫颈表层可能转化成癌的细胞变化情况。如果监测到异常细胞，它们将会被监控，破坏，而且移除。
