Methods: To establish the rat model of spleen-deficiency by the methods of purgation with bitter and cold nature dyugs, omproper diet and overstrain. Immunohistochemistr and in situ hybridization were used to tetect and C-fos and C-JUNmRNA expression in the hypothalamus ventral kernel, the hippocampi CA1 area and forehead cortex.

采用苦降泻下、饮食失节加劳倦过度法建立脾虚大鼠模型，免疫组化法、原位杂交法检测下丘脑腹侧核、海马CA1区、前额叶皮层C-fos水平与C-JUNmRNA表达变化及归脾汤的治疗作用。

When oversubscription happens, underwriters can reduce the level of discount and increase the bottom price by strategic allocation so that both financing cost and IPO underpricing will be less. It suggests that financial supervisor should allow underwriter to allocate IPO stocks freely to a certain extent in China.3. If independent IPO allocation is allowed in IPO bookbuilding, the underwriter and affiliated institutional investor maybe exploit free allocation and information asymmetry to manipulate.

在发生超额认购时，承销商通过有策略地分配股票可以有效地降低折价水平并保证较高的发行底价，减少了发行成本的同时也减轻了IPO抑价程度，建议我国监管当局可以考虑在适当的时候赋予承销商一定的新股自主分配权。3、在有自主分配权的条件下也可能会发生承销商与关联机构投资者共同进行市场操纵的行为。

At last, with this finite element model, this dissertation gave a relatively complete analysis to the lateral seismic nonlinear dynamic responses of the single pile, and analyzed the pile head's response spectrum, earthquake Fouriers spectrum, then a test parametric sensitivity analysis was taken into consideration, including modulus ratio of pile to soil, soil material damping ratio, earthquake input level.

第二，利用该有限元模型，较为全面地研究了地震荷载作用下的单桩横向非线性动力响应，分析了桩头反应谱、地震波傅里叶谱等，进行了桩土弹性模量比、土体材料阻尼比、地震动输入水平等因素对单桩横向非线性动力响应的参数敏感性分析。

As the representative of the northern Loess Plateau gully region, the soil quality under different cultivation length of the orchard in Changwu county was studied. Using partial correlation coefficient to determine the weight, combined with evaluation of membership Sanction to evaluate soil quality levels of the area, the trend of orchard soil quality under different cultivation years was analyzed. The results showed that the IFI values of orchard soil were between 0.22 and 0.70, 27% of them reached the second soil quality standards, 64% reached a third-level soil quality standards, 9% met the fourth standards of soil quality.

以长武北部黄土高原沟壑区为代表，研究了不同果园种植年限下的土壤质量现状，运用偏相关系数法确定权重，结合隶属度函数评价了该地区土壤的综合肥力水平，分析果树种植中土壤质量随着种植年限的变化趋势，结果表明：黄土沟壑区果园土壤IFI值在0.22~0.70，其中有27%达到了2级土壤质量标准，64%达到了3级土壤质量标准，9%达到了4级土壤质量标准。
