The research results suggest that:(1)the factors influence the control of IOR including economic,social and technological factors;(2)the application of interorganizational systems should focus on both technological and non-technological factors;(3)the stronger dependency between organizations, the more effective of the IOS reducing the coordination costs;(4)usually the investment of firms in interorganizational relationship is reciprocal;(5)the appicaton of IT changes the dependency between organizations, which should modify the coordination mechanism, resulting in the change of IOR;(6)the coordination cost affects the effectiveness of coordination among firms;(7) maintaining the interorganizational relationship influences the firms'' network life cycle and matureness;(8)both coordination cost and network size of firms affect sharing mechanisn of the costs and benefits for creating and maintaining interoganizational relationship;(9) the influence of coordination costs to the allocation of super profits deriving from interorganizational relationship is depent on the network topology;(10) the core firm in a network prefer the symmetric network.

我们的研究成果表明：（1）影响管理与控制IOR治理结构的因素有经济因素、社会学因素以及技术因素；（2）在应用组织际信息系统时，要同时关注技术和非技术的影响因素；（3）当组织之间存在较强的依赖关系时，组织际信息系统的应用能够有效减少组织之间的协调成本；当组织之间的依赖关系较弱时，组织际信息系统的应用会加深组织之间被对方侵占的风险，无法显著地减少组织际协调成本；（4）在通常情况下，参与组织际关系的成员的投资是互补的；（5）IT的应用会改变组织间的相互依赖性，组织应调整协调机制，而协调机制的变化会改变IOR；（6）协调成本的大小对协调有效性有着很大影响；（7）组织际关系的维护影响组织网络的生命周期和成熟度；（8）影响组织际关系建立和维护的成本分担和利益共享方案的因素不仅仅跟协调成本有关，而且还与网络规模有关；（9）在对称网络拓扑结构与非对称网络拓扑结构下，协调成本对超额回报分配的影响是不同的；（10）核心企业倾向于选择非对称的网络结构。

During the postgenomics era the information about genomic sequence and gene functions provides a new foundation for evolutionary biology and ecology As the first whole-genome sequenced plant Arabidopsis thaliana and its wild relatives have played a critical role in understanding the evolution of genomics and speciation Both A halleri and A lyrata are closely related to the model species A thaliana A halleri ssp gemmifera occurs in northeastern China Japan and Taiwan; while its sister A halleri ssp halleri is mainly distributed in Europe Geographical barriers such as Tienshan Mountain Range isolate these intraspecific sisters Likewise A lyrata ssp kamchatica and ssp lyrata occur in East Asia and North America respectively Such distribution patterns seem to be consistent with allopartic speciation The comparison between ancestral and extant polymorphism by multilocus can be informative about the population genetics of speciation In this study we collected and analyzed DNA sequences of 98 genes from four wild relatives of A thaliana A halleri ssp gemmifera A halleri ssp halleri A lyrata ssp kamchatica and A lyrata ssp lyrata The ancestral states of these four species were compared to each other in terms of level of genetic variation However the ancestral species at the time of speciation were substantially more polymorphic than the extant geographical populations The observations are not fully compatible with speciation by strict allopatry At some species pairs parapatric speciation seems more reasonable in speciation of Arabidopsis The 98 gene sequences are also used for the congruence test between gene genealogy and species phylogeny Only 28 genes support the species phylogeny but there are 23 genes supports another major genealogy { lyrata} thaliana Based on the phylogenetic position change of A lyrata ssp kamchatica and Ks value for each species pair suggested the recent directional gene flow between A halleri ssp gemmifera and A lyrata ssp kamchatica

阿拉伯芥是第一个完成基因体定序的开花植物，其基因体资讯提供植物学研究的重要依据；在解析阿拉伯芥属物种的亲缘关系以及种化机制等重要的演化议题时，阿拉伯芥近缘的野生物种自然成了不可或缺的关键；跟阿拉伯芥近缘的物种包括A halleri及A lyrata，其中A halleri ssp gemmifera主要分布於中国东北、日本以及台湾，与近缘的A halleri ssp halleri其分布於欧洲隔著天山及大陆的障蔽，而A lyrata ssp kamchatica主要分布於东北亚及台湾，与分布於北美五大湖的A lyrata ssp lyrata被北极圈所分隔，这样的分布模式暗示异域种化的可能。藉由多基因分析比较祖先物种与现生物种遗传歧异度的相关可提供讯息探讨种化时期的族群遗传结构，本研究针对A halleri ssp gemmifera、A halleri ssp halleri及A lyrata ssp kamchatica、A lyrata ssp lyrata四个物种，两对互为亚种的姊妹群，以阿拉伯芥为外群进行研究，在四个物种完成98个同源基因的分子序列，利用套装软体MCMCcoal来估算祖先物种的遗传变异，亦估算现生物种的核苷酸歧异度，观察到？多物种配对中祖先物种遗传多型性大於现生物种DNA歧异度，显示异域种化模型并无法完全解释阿拉伯芥属物种的种化模式，在某些物种配对间邻域种化模式应比异域种化更为可能；在基因树与物种树的比较，98个基因片段的亲缘模式只有28个是与已知物种树一致的，有23个基因其树状图支持{ lyrata} thaliana的型式，藉由kamchatica位置的变化以及估算各物种配对间的平均同义置换率，推测在A halleri ssp gemmifera与A lyrata ssp kamchatica间具有近代的单方向基因交流。

Diamond, an allotrope of carbon, has many physicochemical properties unrivaled by other known materials, such as superhardness, high thermal conductivity, high spectral transmittance and perfect electrical insulation. Thus it is considered an ideal material for many special applications in mechanics, thermotics, optics, electronics and other fields.

金刚石是碳的一种同素异形体，具有许多其它材料无法比拟的物理化学性质，如超高硬度、高导热率、高光学透过率和极好电绝缘性，因而在力学、热学、光学和电子等领域有许多特殊的应用价值。

I think my mother's pie was missing all the seasonings. Maybe she couldn't afford cloves, brown sugar and allspice. I think she used the pumpkin straight from the can.— Anne Duston, Chicago, Illinois

很多年以后，我知道了南瓜馅饼吃起来应该像什么，妈妈的馅饼没加任何调味料，也许她无法负担丁香、红塘和五香粉，她只用了南瓜和两只手。

"Then we do not see those beings to whom you allude?"

"那么说我们是无法看见您所指的那种人了？"

At the same time, he does not allow himself to be made a prisoner of physical allurement. Instead, the retention of the maternal legacy, which has become an emblem of the material idol, harkens back to his concealed and irreplaceable fond reminiscence of the maternity.

同时，他不让自己驻守在肉欲之中，而让母体残余，现在已经变成了的物欲偶像符号化，是希望隐藏那种无法去除的对母体的温暖回忆。

I almost couldn't believe it ...

我几乎无法相信这。。。

Without such data, we could not be positive that ALOD was a complication related to plates.
