A list of the new solution is created by inserting properties of a guide solution into an initiate solution. The list is used to update reference set in order to evolute the solution. The solution update method of the reference set with diversification detection and decentralization mutation strategy is proposed in the path relinking algorithm.

路径重连算法维护一个由高质量解组成的参考解集，将一个向导精英解的属性逐步引入一个起始精英解而形成的中间解序列，并用此中间解序列更新参考解集以获得进化。

As showed above, we could draw the conclusion that H3 viruses could cause outbreaks or local epidemics in Shanghai for the immune of population to the new emerging antigenic drift was still unknown though there was strong immune barrier to the previous vaccine strain, H1 viruses also may caused epidemics as the population had a weak immune protection to the previous reference strains A/New Caledonia/20/99-like and part of the recent isolates were distingwishing from them and continued to evolute on the new reference strain, and H5N1 HPAI activities has expanded its geographical range thus increasing the size of the population at risk as the continuing emergence of human cases which give the virus an opportunity to evolve towards a fully transmissible pandemic strain. We should keep eyes on the human cases of avian influenza virus an its variation for the H5 isolates in Shanghai also has the possibility to infect human directly and the infection of H5, H9 viruses had previously occurred in the population especially in those contacting with animals.

综合上述分析结果，我们认为上海地区人群虽然对原有的H3亚型参考病毒株有较高的免疫保护，但H3亚型病毒HA已出现新的抗原漂移，人群现在对新变异株的保护水平尚未知，有可能在未来引起局限性暴发甚至地方性流行；人群对H1亚型流感病毒免疫保护水平低，同时H1亚型流感病毒株部分与原推荐疫苗株抗原性差别较大，并在现推荐疫苗株基础上继续变异，需警惕发生流行的可能性；H5N1亚型高致病性禽流感地域范围扩大，人间病例不断发生，存在演变成大流行株的威胁，上海市H5亚型禽流感病毒株存在跨宿主屏障感染人类的可能性，而且已发现人群尤其禽、畜类动物接触人群中存在H5、H9亚型流感病毒的既往感染，应警惕禽流感病毒的变异和人间病例的发生。

Since all javascript syntax functions derive themselves from the base-class function, it is unnecessary to provide an explicit reference to the self-object: from anywhere within an ECMA-style script, you can obtain a reference to the self-object through the keyword "this", which is the same as the "me" keyword, but with minor differences.

因为所有的javascript语法中函数都是从基础类函数派生而来，它们不必显示的声明指向自己的对象：在ECMA风格脚本的任何地方，你都可以通过关键字"this"获得指向当前对象自己的引用，就象关键字"me"的功能一样，只是稍有不同。

With reference to the various e-mails exchanged and with reference to our preliminary survey report we are obliged to inform you that irregularities do not seem to be related to a fortuity during the transit period i.e. holed / punctured container, sea / rainwater ingress.

根据我们交流的多封电子邮件和我们之前的调查报告，我们很遗憾的告知你，变形似乎与运输过程中的偶然事件无关，这些偶然事件包括划破/带有刻点的容器，海运/进了雨水。

In this dissertation, digital lock-in detection techniques under integer period sampling and non-integer period sampling are separately investigated (1) Under integer period sampling, digital signal sequence is acquired through sampling the measured signal, but digital reference sequence is acquired through mathematical operation, then digital lock-in detection can be realized by calculating crosscorrelation function of digital signal sequence and digital reference sequence Harmonic measure is also analyzed, and a method of measuring harmonic of a periodic signal under aliasing is put forward.

本文对使用采样ADC把模拟信号转换为数字信号并通过计算数字信号的相关函数来实现锁定检测的技术进行了研究，在此基础上设计了一个多功能的数字LIA并在一些科学实验中进行了应用。本文对整周期采样和非整周期采样时的数字锁定检测技术分别进行了研究。(1)在整周期采样时，对被测信号进行采样得到信号序列，而参考序列由数学运算得到，通过计算信号序列和参考序列的互相关函数就可实现锁定检测。
