Considering just-in-time production, the mathematical model of flexible job-shop schedulingfor bi-objective is established. To solve the model, a genetic algorithm is developed. In this algorithm, a two-row chromosome structure is presented because of the special point of the model. At the same time, AOV network is applied to decode and compute the fitness function. Then selection, crossover and mutation operator of the genetic algorithm are designed. Finally, an example of job shop scheduling is shown.

同时考虑现代生产准时制的要求，建立了柔性作业车间调度问题的双目标数学优化模型，并给出了求解模型的遗传算法的具体实现过程；针对模型的特殊性，提出了染色体两层编码结构，将AOV网络图应用到解码和适应度函数的计算中，通过一个调度实例进行验证，给出了相应的选择、交叉、变异操作设计方案。

Beijing Fatty Chicken, Langshan Chicken and Small-tailed Han Sheep were selected as experimental material. Fibroblast library was constructed through tissue confluency culture and cell freeze technology. Growth dynamics, genetic stability and contamination of of cross breeds etc.were detected through growth curve, chromosome analysis, isoenzyme analysis etc. Cloning and sequence of gene GPAT of Beijing Fatty Chicken was analyzed by cloning technology and software related.

本论文以北京油鸡、狼山鸡、小尾寒羊为研究对象，采用组织块贴壁培养法和细胞冷冻技术构建成纤维细胞库，采用生长曲线、染色体分析、同工酶分析等方法对细胞生长动态、遗传稳定性、种间交叉污染等进行检测；采用基因克隆技术和相关分析软件对北京油鸡GPAT基因进行克隆和序列分析。

Objective The human PrP gene locates at the short-arm of the 20th chromosome.

目的 鉴定朊蛋白基因转录启动子位置。

As a result,1A360 probe did hybridize strongly to Tester DNA sample,but weakly to Driver DNA.Thus,our two rounds of RDA are proved to be specific andeffective.Because of not hybridizing to the liver tissue DNA of rat and the thymicDNA of bull,so the probe is species-specific and gained from human chromosome.

该探针不能与鼠肝组织和小牛胸腺组织DNA杂交，说明它来源于人源染色体并有种属的特异性。1A360基因片段探针还与多种胃癌细胞系，胃癌组织DNA有较强的杂交信号，与其它肿瘤DNA有强弱不等的杂交信号。
