遗传作用

The positions and functions of the inventory control in the environment of supply chain are discussed first. The analysis on main conflict problems needed to be determined is presented. Based on the algebraic Petri nets the modeling research on vender managed inventory is proceeded on. Considering the shortages of the original algorithms, the improvements are putout to speed up the search process and improve the precision of the search results. The optimizations of lots sizing problem with the objective function of inventory costs are processed by the improved optimal algorithms. By the analysis on the results of the optimization, the conditions of overtime work, out of stock, and security stock are achieved.

文章首先讨论了供应链环境下库存控制在物流管理中的地位和作用，分析了库存控制需要解决的主要矛盾；然后应用代数Petri网对供应商管理库存(Vender Managed Inventory，VMI)的模式进行了建模研究；针对原始的粒子群优化算法和遗传算法存在的不足，分别提出了改进型算法，提高搜索速度和搜索精度；运用改进的优化算法对以库存成本为目标函数的批量计划问题进行了优化，通过优化结果的分析，得出了批量生产计划安排中加班、缺货和安全库存的存在条件。

There may be synergistic action between D and T alleles in pedigreed primary hypertension.

结论家族性原发性高血压与ACE基因I/D多态性及CYP11B2基因T（-344）C多态性之间具有相关性。D及T等位基因频率增高是原发性高血压患者家族中ACE基因I/D多态性及CYP11B2基因T（-344）C多态性的分布特点。D及T等位基因可能在家族性原发性高血压遗传中起协同作用。

After analyzed the situation of the major industrialproducts in area of Hubei Province it put forward some principlesand factors that influenced the choice of these products, andsummarized five parterres of development, including Defir Choiceof the major products, applying the Fuzzy comprehensive evaluationduring choosing the major products, the second sieving products,applying the Analytic Hierarchy Process during choosingproducts, and applying the Genetic Algorithms during theproducts sieving enterprises.

方法研究是本文的重点，在这一部分提出了选择重点产品的德尔菲法、模糊综合评判法、二次筛选产品法、层次分析法、遗传算法，并进行了应用分析。这些方法对产品的选择提出了不同的模型和见解，对于我国地区重点工业产品的确定将有十分重要的现实意义和指导作用。

It helps to understand some evolvement processes of species, especially in dynamical system. For instance, studying the growth of cod fish simulation of wolf in Alaska, relationship between death age and relatives, evolvement. of species, evolvement process of competition, reproduce and natural selection of haploid, and one-species cellular automata model based on the Penna model was founded on a lattice of two dimensions.

利用Penna模型有助于理解一些生物演化过程，尤其是在种群动力系统中发挥了重要作用，如北极鳕鱼生长的研究，Alaska狼群模拟，近亲遗传死亡年龄之间的关系，种群的演变，单倍体种群的竞争，繁殖，自然选择等种群演变过程，二维格子上建立基于Penna模型的单物种元胞自动机模型是Penna模型与格子结合的早期文献。

Two outstanding fusants SR-7 and SR-T19 were chose out in the fusion group 90-11×FR-008, the former produces not only antibiotics the parents produced but also a new antibiotic effective gainst a wide range of both gram positive and negative bacteria, which the parents could not produce, and its product of the 37℃ fermentation was very effective against the cotton seedling damping off caused by Rhizoctonia sonali while product of the 26℃ was effective agaist the bacterial rots of turnip and Chinese cabbage; the latter have a much stronger activity against a wide range of fungi and yeasts than the parents.

在90-11×FR-008融合组合中，筛选获得2个优良融合子SR-7和SR-T19，前者除产生亲本产生的抗生素外，还产生亲本不产生的一种新的具有广谱抗细菌活性的碱性水溶性抗生素，防病试验表明，其37℃发酵产物对棉花苗期立枯病具有良好的防治效果，28℃发酵产物对萝卜和大白菜具有明显的防腐作用；后者与亲本FR-008的抗菌谱完全一致，但其活性强度都超过了FR-008；采用RAPD分子标记技术检测了SR-7和SR-T19与亲本的同源性及彼此间的差异，从而首次直接从DNA分子水平上验证了链霉菌的原生质体融合子及其遗传重组的多样性。
