In the part of empirical analysis of Chinese IPO first-day return, the difference between existing study and this study is that we use principal components analysis to extract from five factors to construct investors'sentiment index, add it to controled varibles, on which we examine the influence of offering mechanism on IPO first-day return. Moreover, we gather statistics and compare the IPO holding return for lockup period between fixed-price-class offering method and bookbuilding-class offering method, as well as price range between Chinese A-share market and Hongkong stock market, which prvide comprehensive evidence to appraise Chinese IPO bookbuilding mechanism. 2. Compare to the existing literatures which consider discount or allocation, incentive allocation and discount are considered at the same time in optimal mechanism design in this dissertation, and the offering bottom price is introduced to the price range. We investigate the relationship between price range and allocation quantity, and obtain the optimal price range and allocation strategy so that the advantages of independent allocation are reflected. On the other hand, the disadvantages of independent allocation are reflected in the manipulation in case of no restriction on IPO allocation. To distinguish from the existing literatures, bookbuilding mechanism is introduced to the model. We study the allocation strategy adopted by the underwriter in the pooling equilibrium of manipulation. In addition, we analyze the incentive compatibility conditions to which the existence of pooling equilibrium should satisfy and examine some factors'impact on the existence of manipulation.3. In bookbuilding without independent IPO allocation, Chinese realistic IPO background is considered and the condition of bookbuilding and fixed-price hybrid offering is added. Divide bookbuilding and fixed-price hybrid offering into sequential hybrid and simultaneous hybrid, and point out that the key points of subscription strategy in the two kinds of hybrid are different. Through modeling and simulation we obtain the impact of institutional investors'subscription strategy on bookbuilding without independent IPO allocation, which fill the gap in related research. Moreover, in the part of IPO bookbuilding with over-allotment option, the pricing strategy is divided into hot-IPO strategy and weak-IPO strategy. Take into account the procedure of Chinese IPO with over-allotment option, it presents how the underwriter determines the pricing strategy and what effect it brings to offering price and issue size through modeling and simulation. Therefore, it is instructive as a complement to existing literatures.

Genetic cluster analysis is similar based on the results of morphological and DNA markers, the five populations could be divided into three groups. But there are different groups sort of individual locations, reflecting the similarities and difference about the analysis of the relationship between population with the two kinds of markers, It could be concluded that there was coupling and relevance to some extent in evaluating genetic diversity with the same experiment sampling by morphological and SSR marker variation. However, there was also differences. In research, the two can complement each other.8.

新疆野扁桃遗传多样性不同研究分析方法结果的比较与评价表型与DNA二种水平的遗传标记方法揭示的遗传多样性水平有差异，表型性状比DNA分子标记具有更大的变异性；其受到环境的影响较大，也即对环境更敏感。2种水平的遗传标记聚类结果将野扁桃5个不同分布群体均可分为3个大类群，但是出现有个别不同的群体排序位置，反映了2种标记在分析种群间关系上的异同性，从本研究结果来看，说明表型与DNA标记有一定的耦合性和相关性，但也存在差异，在研究上可以互为补充。8。
