CBFEC emphasizes direct correspondence of concepts in EC with its software architecture for ease of understanding and using; minimal coupling with specific problem structure for easy adaptation it to solve a large number of wholly different problems; interface-centered design for extendibility. To achieve those objects, the problem-solving method of EC is analyzed and the problem-solving procedure of EC is divided into three interactive aspects: population-based stochastic searching mechanism, problem specific information to implicitly guide the stochastic searching, and the observation and control of the computation procedure of EC. Then the key concepts of EC are identified in those three aspects; the normal implementations of those concepts are summarized; the interfaces represents those concepts in software are abstracted; the collaborations of components through those interfaces are designed. CBFEC is implemented on mainstream component software platform COM/DCOM (Component Object Model/Distributed COM from Microsoft), which includes interfaces definitions, commonly using EC components implemented those interfaces, such as Simply EA component, Steady State EA component, EA component, EA component, Population component, Tournament Selection component, Linear Ranking Selection component, Nonlinear Ranking Selection component, Random Number Generator component, etc, and the collaborations of those components through those interfaces.

具体的做法是把演化计算看作是基于组件的软件工程的一个应用领域：首先分析了演化计算求解问题的一般思路和方法，把演化计算问题求解过程分为："设计基于群体的随机搜索机制"、"研究问题的性质并以此隐含地定义算法的搜索方向"和"求解过程的观察与控制"三个部分；然后分别找出各个部分中的关键概念，总结这些概念现有的一般实现方法，抽取其本质，以此结合设计模式来定义组件软件的接口；通过分析演化计算各个概念之间的相互联系来设计组件软件间通过接口的进行交互的方式；最后还在目前一种主流组件软件开发平台COM／DCOM（微软提出的组件对象模型）的基础上实现了常用的演化计算组件，如简单演化算法组件、稳态演化算法组件、演化算法组件、演化算法组件、种群组件、锦标赛选择策略组件、线性排名选择策略组件、非线性排名选择策略组件、随机数发生器组件等等。

Erysimi CarE activity both of resistant populations and of susceptive population were trend to normal school, and the resistant L. erysimi populations have significant higher CarE activity than susceptive L. erysimi population. Thereinto, the activity level of CartE in Hongtang L. erysimi population is the highest among the four field populations, which is tally to the result of drug-fast test on each population.

对各地菜缢管蚜种群个体羧酸酯酶研究结果表明，无论是抗性种群还是敏感种群，其个体羧酸酯酶活性分布频率均趋于正态分布，即两头低，中间高；各抗性种群的羧酸酯酶的活性水平明显高于敏感种群，其中以洪塘菜缢管蚜种群的羧酸酯酶活性水平最高，这跟各种群的抗药性监测结果亦相吻合。

Results: B6-Co mice showed higher sterile rate, and significant lower average litter size and survival rate at weaning than the normal B6 mice, but the time interval between deliveries was shorter in the mutant population. During the first two weeks after birth, the growth performances were not significant between the mutant mice and the normal ones, but after that, the mutant mice grew much slower. The differences were significant in the indexes of eyes, lungs, thymuses, and adrenal glands between the genders. At the same time, the differences were significant in the organ indexes, such as lungs, adrenal glands, uterine and testicles between the normal phenotype mutant mice and the abnormal ones. And these two kinds of mice showed different amount of hemoglobin and red blood cell.
