In this paper, Genetic Algorithms (GA) as used in regression analysis is introduced. The GA is programmed with Database (FoxPro 2.6 for Windows),in which the gene is transferred into field, chromosome into record, population into table, and genetic operator into database's operator. With the proposed Genetic Algorithms, regression analysis is made much simpler, and the regression results are found to be very accurate, stable and reliable.

采用遗传基因算法实现切削数据的拟合,用数据库技术实现算法—将基因(gene)视为字段、染色体(chromosome)视为记录、种群(population)视为库,以数据库的基本操作替代遗传过程;解决了传统回归分析方法的不足,使回归过程简单、结果稳定、可靠,并为回归分析提供了一条新途径。

In1909,Johannsen coined the word “gene”, shortened from the pangene of de Vries and ultimately derived from Darwin’s word pangenesis,to denote the unit of heredity.It was an outstanding example of“weeding through the old to bring forth the new ”.

1909年 ,约翰森创造“基因”(gene)一词作为遗传单位的名称。该词是由德 弗里斯创造的“泛生子”(pangene)一词缩短而成的 ,而“泛生子”一词则衍生于达尔文提出的“泛生论”(theoryofpangenesis)。约翰森的这一创造堪称“推陈出新”的典范。

Fifty-three scientists gained Nobel Prize because they researched gene since 1909.The successful factors of these scientists were analyzed, such as materials, research thought, and others.

从1909年Johannsen提出基因(gene)一词至2004年以来,因研究基因而获得诺贝尔奖的达53人之多。从材料的选择、科研思想、课题设计、理论实践等方面,分析和探讨这些科学家的成功的因素。
