The author writes this paper in order to explore these advantages so that the enterprises selling agricultural production means by chain operation can better find and utilize these advantages to promote the smooth development of chain operation of agricultural production means 探讨农资连锁的优点以便实行连锁经营的农资企业能够更好地认识和发挥这些优点,推动我国农资连锁的健康发展,即是本文研究目的之所在。
The ms188 gene was finely mapped . a total of 8 new indel markers were designed to map msl88 using a segregating population with a total of 2135 male sterile progenies . ms188 was finally mapped to a region of 95 . 8kb between the molecular marker mda7 and k24c1 在与ms188连锁的分子标记mc015附近设计了8个indel分子标记,对遗传群体中2135株不育植株进行基因型分析,最后将目的基因定位于第五条染色体分子标记mda7和k24c1之间95 . 8kb的区间内。
In sporophytically self - incompatible brassica , three s - linked genes , the pollen ligand scr , stigma receptor slg and srk , have been identified . in addition , four genes ( arc1 , thl1 , thl2 and mod ) that do not link to s locus have also been found , they are regarded as downstream protein factors of self - incompatibility ( si ) response , however , their biological function is not clear 在孢子体型自交不亲和的芸薹属中,已经鉴定出3个主要与s位点紧密连锁的基因,花粉中的配体scr和柱头中的受体slg与srk :另外鉴定出4个不与s位点连锁的基因arc1 、 thl1 、 thl2和mod ,它们被认为是si反应的下游蛋白质因子,但是对它们的生物学功能了解的还比较少。
3 ) we tested total - family association , within - family association ( via tdt ) , and linkage , between the bsrbl marker and bone phenotypes ( bmd and bone size ) at the spine and the hip ( femoral neck , torchanter and intertrochanter ) in chinese 402 nuclear families with a total number of 1263 , and found the suggestive linkage ( p - 0 . 037 ) between the il - 6 bsrbl maker and the li _ 4 spine bmd . no significant association and linkage was found for bone size and hip bmd . the present studies represented molecular genetic research of bone mineral density , and identified some factors related to bmd in chinese 3 )在征集的402个核心家庭包括1263个个体组成的上海样本中,利用传递不平衡检测法( tdt ) 、关联分析和连锁分析,检测了白介素6基因和不同骨骼位点(腰椎、股骨颈、大转子、转子间区)的骨密度、骨大小之间的连锁和/或关联关系,并发现白介素6基因的bsrb工标记和控制腰椎骨密度的数量性状位点( qtl )之间存在连锁的证据( p = 0 . 037 ) 。
First , the article briefly introduced the implication and three kinds of basic modes of the chain operation . when exploring the advantages of the chain operating , the author made his view that the low - cost advantage can not explain the enormousvitality and enormous vitality of chain comes from the numerous advantages on the marketing ; introducing the chain of three basic forms , the article mainly discussed their basic features 首先,文章简要介绍了连锁经营的定义、本质、优势和三种基本形式。对连锁经营的优势探讨时,认为成本优势不能解透彻解释连锁的巨大生命力,连锁的巨大生命力源于它营销方面的诸多优势合力;介绍连锁的三种基本形式时,主要介绍了它们的基本特征。
At last the conclusion is drawn , that is , according to the retail - needs theory , what the customers ’ needs guide the choice of the retail shape in the separate market . the shape is optimized in the separate market . in the end unify the shape in the way of chain so as to get the optimization in resource distribution 最后得出结论,根据零售需求理论,零售企业在对业态的选择方面必须从消费者需求出发,进行市场细分,在不同的细分市场进行业态优化,最后把这些优化后的业态以连锁的方式加以形式整合,达到资源的最优配置。
