Effects of dry temperature and dry time on properties of heat cured sand and the relationship with binder composition are as follows:sands bonded by binders that are not modified have high strength when dry temperature is high and dry time is long,but their anti-wettability power is poor . Sands bonded by binders that are modified by B but not modified by M can be dried quickly and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M but not modified by B can also be dried quickly to obtain maximum strength,then the strength becomes lower when they are dried continually for more time. and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M as well as by B at the same time can be dried quickly to obtain maximum strength at low temperature and short time. But the anti-wettability of sand mold is best when they are dried at high temperature and long time.

烘干温度和烘干时间对热硬砂性能的影响及其与粘结剂改性的关系是：未经改性剂B和改性剂M改性的粘结剂砂，脱水速度较慢，烘干温度越高，时间越长，则硬化强度也越高，但未经改性的粘结剂热硬砂的抗吸湿性较差；经改性剂B而不经改性剂M改性的粘结剂热硬砂，烘干硬化速度较快，强度也高，但在高湿度下的抗吸湿性不好；经改性剂M改性而不经改性剂B改性的粘结剂热硬砂，烘干时强度先随烘干时间升高至最大值后，继续烘干时强度又出现下降；经改性剂B和经改性剂M共同改性的粘结剂热硬砂能在短时间和较低的烘干温度下就可烘干到最高强度，即烘干脱水的速度较快，但试样的抗吸湿性差，若在更高温度和更长时间下烘干，试样的抗吸湿性得到改善，综合考虑烘干强度和抗吸湿性要求，对于φ30×30mm试样，理想的烘干温度是200℃，烘干时间20分钟。

Although this one practice cannot say to do not have any effects, but old practice proof, this kind of practice not from go up at all solve a problem, this explains traditional point of view is suspectable, because be in density of a few population is exorbitant, the country that rich is in short supply relatively, resemble 4 small dragon of Japan, Asia for instance such a few countries, the government was not target of implementation obtain employment and the concentrated degree of technology of the investment direction to the industry, capital and labor undertakes adjust and intervening, solved serious obtain employment problem instead, does the reason where?

这一做法虽不能说没有任何效果，但多年的实践证明，这种做法并未从根本上解决问题，这说明传统的观点值得怀疑，因为在一些人口密度过高，自然资源相对短缺的国家，比如象日本、亚洲四小龙这样一些国家，政府并没有为实现就业目标而对产业的投资方向、资本技术和劳动的密集程度进行调整和干预，反而解决了严重的就业问题，原因何在？

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.
