Therefore,the dissertation has constructed the model reflecting the impact of the cross-level embeddedness of cluster enterprises on enterprise cooperative innovation performance,i.e.the conceptual model of cluster enterprise cross-level embeddedness - interorganizational interaction - cooperative innovation performance,based on the interrelationship among cluster enterprise cross-level embeddedness,interorganizational interaction and cooperative innovation performance,and in combination with the literature reviews and on-site investigations.

本文根据集群嵌入性不同层次间、以及其与组织间互动、合作创新绩效之间的关系，结合文献阅读和实地调研，构建了反映集群嵌入性对企业合作创新绩效影响的模型，即&集群嵌入性—组织间互动—合作创新绩效&的概念模型。

And, by adding the self-adaptive temperature decay coefficient, made the SA algorithm could auto-tune the search criteria according the environment, avoid the deficiency of premature convergence.

针对微粒群优化算法在求解作业车间调度问题时存在的易早熟、搜索准确度差等缺点，在微粒群优化算法的基础上引入了模拟退火算法，从而使得算法同时具有全局搜索和跳出局部最优的能力，并且增加了对不可行解的优化，从而提高了算法的搜索效率；同时，在模拟退火算法中引入自适应温度衰变系数，使得SA算法能根据当前环境自动调整搜索条件，从而避免了微粒群优化算法易早熟的缺点。

The Sichuan, Baojing and Shimen populations composed core clade, and then gathered with the southern and northern populations, respectively, based on the UPGMA analysis.

基于遗传距离的UPGMA聚类中，位于华西的四川居群和中南的保靖和石门居群组成核心分支，再分别与向南和向北的居群聚合。

After be pregnant fight in some places one by one is added close child, learn and communicating Yo experience, meantime is mixed in pet group in, play the friend of the dog one case with a flock of dogginess group smooth, communication.

怀孕以后又转战加亲子，学习和交流着育儿经验，其间混在宠物群里，和一群爱狗玩狗的朋友一起群溜，交流。

The results of POPGENE analyze indicated that it was moderate level of the genetic diversity of Dipelta, mean PPB (percentage of polymorphic bands) h and I of 4 species of Dipelta as below: D.wenxianensis.(PPB=62.02%,h=0.1850,I=0.2826); D.yunnanensis (PPB=40.31%, h=0.1238, I=0.1874); D. floribunda (PPB=36.82%, h=0.1395,I=0.2045); D. elegans (PPB=15.51%, h=0.0583,I=0.0861). Genetic diversity in D.elegans is the lowest. It is possibly caused by the endemic distribution and local ecotope.

POPGENE分析结果表明，文县双盾木的多态位点百分率平均为62.02%，Nei&s基因多样性指数平均为0.1850，Shannon&s信息指数平均为0.2826；云南双盾木的PPB平均为40.31%；h值平均为0.1238；I值平均为0.1874；双盾木两个居群的PPB平均为36.82%；h值平均为0.1395；I值平均为0.2045；优美双盾木两个居群的PPB平均为15.51%，h值平均为0.0583；I值平均为0.0861；因此，我们认为双盾木属4个种的遗传多样性适中；而优美双盾木由于分布上的地理限制，居群的生境比较孤立，其遗传多样性较低。

Our results showed 1 The changes in trends of leaf traits response to the rainfall gradient differed either with species or with a specific trait; 2）The same trends were found at the functional group level, However, leaf traits for grasses tends to be less sensitive, then for forbs, and the legumes is the most sensitive functional group along the rainfall gradient, indicated that the Grass function group is quite strong to the soil moisture content tolerance, and which certainly explained to the local vegetation distribution and the substitution between species.

主要结论如下：1 叶片性状在降雨量梯度上的变化趋势在物种水平上表现出多样化的特点，性状的变化趋势是否有显著的格局取决于物种或特定性状。2 叶片性状对水分梯度的响应在功能群水平上表现出各自的特点，Grass功能群对水分梯度的响应敏感性较低，Forb居中，Legume表现出较强的敏感性，表明Grass功能群对水分的耐受性比较强，这在一定程度上解释了当地克氏针茅草原上目前以禾草类为主的现状，对物种之间的替代有一定的指示性。
