ObjectivesThe objective of this research topic is to investigate the effective compound of Giant knotweed Rhizome against the anti-Friend Murine Acquired Immunodefiency Syndrome (Friend-MAIDS) of reservatrol in vivo and discuss its anti-viral mechanism.

目的 本课题研究的目的是通过体内实验，研究中药虎杖有效成分白藜芦醇的抗Friend型鼠艾滋病作用，并初步探讨其抗病毒作用的机理，为开发传统中药有效抗病毒单体，并应用于临床提供可靠的实验数据。

Quantifying similarity/difference between two objects plays an important role in many contexts The quality of the similarity/difference scores can be improved by considering the semantic information related to the features of objects A flexible semantic distance function called X Dist is proposed, which can utilize the semantic information to measure the difference between two objects based on a solution to the transportation problem from linear optimization With a ground distance function for single features being a metric, X Dist is also a metric This property is very useful for making searching efficient, but is not investigated in the previous research Moreover, the experimental results show X Dist can be as good as the previously studied similarity measures in nearest neighbor searching, discriminative power and computing speed

量化对象间相似性/差别的方法具有广泛的用途，利用相关的语义信息能够得到更好的量化结果提出了一个量化对象间语义差别的距离函数XDist，它基于线性优化中的运输问题模型和相关的语义信息量化两个对象之间的差别在量化特征的差别函数是度量的情况下，XDist是一个度量，在提高搜索的效率方面具有优势，弥补了以往研究的不足，而且实验初步表明，此函数在最近邻查询效果、差别分辨力和计算速度方面能与已有函数相媲美1 引言量化对象间相似性/差别的方法具有广泛的用途，例如数据挖掘中的聚类；信息检索中的相似文档查询；协同过滤中的相似用户查询；CBR中的相似案例查询集合是对象特征表示的常用结构，集合的元素是与对象特征相关的项，它们可以

Progenies of 40 selected individuals were tested. Some super clones of seashore mallow were selected with the increase of oil content from 18 % to 23 %. We acquired the biodiesel sample in the lab from the seeds of seashore mallow in 2005 and its quality examination report from SINOPEC.

目前已经初步选育出了海滨锦葵优良无性系，含油量从原群体平均的18 %提高到23 %。2005年首次从耐盐油料植物海滨锦葵中成功获得生物柴油实验室样品，并已经得到中石化权威机构检测数据。

It can be time-consuming to replace the preliminary measures, particularly now that observations get published in the mid-month Minor Planet Supplements that are issued weekly.

不断的更改初步测量数据对我们来说是非常耗时间的。现在观测报告在每月月中发表于每周出版的小行星增刊上。

Taking moving average method for the representative of technical analysis, this thesis examines the historical samples of stock market index to evidently test its ability of acquiring extra return and avoiding risk, together with the stability of its performance under different market conditions.

本文以移动平均法为代表，采用股市指数历史数据进行模拟交易，对该方法获取超额回报的能力、规避风险的能力及其在不同市场表现的稳定性进行实证分析，并对分析结果作初步理论探讨。

In this paper, we mainly discuss some preliminary studies about statistical diagnostics for one kind of restricted multivariate linear regression model. At first, we give the parameters estimation of this model. After that, the problem of outlier test is considered by giving the equivalence relations of estimators and statistics in multivariate case deletion model and mean shift outlier model under the restricted condition.

本文主要讨论的是一种带线性约束的多元线性回归模型（这里的多元是指多个因变量对多个自变量的情形），重点在与统计诊断方面的一些初步研究，首先给出带有线性约束的多元线性回归模型的参数估计，其次讨论了该模型的异常点检验问题，主要介绍了常见的数据删除模型及均值漂移模型，并证明了此两种模型统计量之间的等价性。

All these evidences suggest that the present outcropping basements of the Yangtze craton are free of a united evolutionary history.

与已有数据相结合，初步认为扬子克拉通目前所出露的基底没有统一演化历史，对扬子克拉通的基底有待更深入的研究。
