So, in this paper double principle-agent model is employed to design the optimum governance structure and mechanism to reduce the agency costs of companies, control the proportion of small shareholders' interest which is seized on by big shareholders,mediate the conflicts between the principles.it aims at realizing the maximal interset of all stockholders.

我国上市公司的多重股权结构的存在使得上市公司中不同类型的股东之间的利益、目标有很大差异甚至冲突，传统的单一委托代理模型对上市公司并不是很适用，所以采用双重委托代理模型更有利于设计最优的治理结构和治理机制，降低代理成本，有效控制控股股东或大股东恶意侵害中小股东利益的程度，缓和委托人之间的目标冲突，尽力实现全体股东的利益最大化。

The results of the present research are as follows, The correlation between physico-chemical properties of organic compounds and their competitive power was studied, and it was indicated that organic compounds preferable to form H-bonding with organic matter of sorbents have stronger competitive power; Sorption behaviors of ionizable organic compounds in different species and their competitive power were examined, and the results showed that phenols and carbonxylic acids with benzyl circle have much stronger competitive power in molecular species than in ionized species, because negative charges of anionic forms can depressed their adsorption on the surface of the sediment; in contrast, organic bases such as aniline and p-chloroaniline show weaker competitive power in molecular species than in ionized species, and this is because both species of the organic bases could adsorb strongly onto the sediment; there is a correlation between competitive power of organic pollutants in multi-solute systems and their sorption isotherm nonlinearity in single-solute systems, and organic compounds whose sorption isotherms is linear in single-solute systems hardly have competitive power in multi-solute systems; Competitive sorption effects in more than two-solutes systems was studied, and it was exhibited that mixture of two cosolutes each of which could suppress sorption of nominal solute onto the sediment had synergistically competitive sorption effect on the nominal solute; A method about incorporating sorption/desorption of organic pollutants into river water quality model was developed, and discussion about degree of sorption/desorption effect on model prediction for different organic compounds was made, which will provide theoretical basis and practical processes for setting up more accurate water quality model.

论文主要取得了以下研究成果。(1)有机化合物的吸附竞争能力与其物化性质具有相关性，易与沉积物有机质形成氢键的化合物其竞争能力也比较强；(2)可离子化有机化合物的吸附竞争能力与其存在形态有关。酚类、含苯环的羧酸类化合物，其离子态的吸附竞争能力远小于分子态，其机理为有机酸阴离子所带的负电荷抑制了表面吸附能力，主要发生分配作用；而苯胺类化合物，其离子态和分子态都表现出显著的竞争能力，而且离子态的竞争能力略强于分子态，原因在于有机碱阳离子所带的正电荷促进了其表面吸附能力；有机化合物竞争能力的强弱与其单组分吸附等温线的非线性程度具有一定的相关性，吸附等温线近似为线性的化合物没有或只具有微弱的竞争能力；(3)对目标有机化合物的吸附具有竞争效应的有机化合物混合后，将对目标有机化合物的吸附产生协同竞争效应；(4)以京杭运河为例，率先提出了将有机污染物的吸附／脱附作用及水文水力参数耦合到水质模型中的方法，并讨论了吸附／脱附作用对不同有机污染物预测模型的影响，为建立更准确的水质模型及进行更客观的风险和生态评估提供了参考依据。

By taking into consideration the above problems, the thesis adheres to overall standpoint and unrepeated viewpoint in intention, puts goals of psychological health in order, reorganizationally and structurally and closely examines every goal of education of psychological health arranged proceeding in all cases from the practice on the basis of seriously defining the controversial concepts, such as psychological diathesis, perfect personality, good individuality, etc.

但目前无论是心理健康教育的理论与实践工作者还是教育行政提出的心理健康教育目标，在落实的过程中，都不同程度地存在一些问题：一是笼统模糊与面面俱到两极分化的问题；二是内涵重复、缺乏对要素进行内在整合的问题；三是概念不统一、层次混乱的问题；四是不能从心理健康教育实际出发，出现目标定位不准的问题。

The result pointed out that the vertical distribution of foliage for each species was different,however,generally speaking,the foliage in upper crown (0.3CL) for broad-leaved species in natural secondary forest took a small percentage,about 10%;in middle or middle lower of the crown(0.4CL to 0.8CL) the branches here took the majority percentage of whole foliage,almost 60%to 75%;but in lower crown(0.8CL),there was about 10%of whole foliage.(5)The interspecies competition of trees in secondary forest was expressed by Hegyi competitioin index,and the active competitor was calculated by the competition zone radius and the tree position,DBH,and distance in the zone,it was not all competitors in tranditional calculation.The study introduced crown area overlap index to describe the crown competition between subject tree and its competitors,furthermore,the crown area was classified into 5 levels with a method of equal crown projection area,therefor,the resulting crown area overlap index showed more realities of existing stand conditons.(6)Based on the theoretics of multiply divide,the spatial strcture optimizing model of secondary forest stand selective thinning was developed by diversity mingling,aggregation index,competition index and crown area overlap index,also designed 10 constraint conditions which were related to forestry meanings,the objective function was solved by the implicit enumeration method with LINGO 9.0,using 0-1 integer programming.

并且得出，每个树种在树冠内相对高度上的叶量的垂直分布是不同的，天然次生林阔叶树种的叶量在树冠的上部(0.3CL以下)所占比例很小，约占10%左右；在树冠的中部以及中下部(0.4CL～0.8CL)，叶量所占比例最大，几乎集中了整个树冠60%～75%的叶量；而在树冠的下部(0.8CL以下)，几乎占很少的叶量，大约10%左右。5、采用Hegyi竞争指数来表现次生林内林木的竞争关系，并且根据竞争圈的大小和林木在竞争圈内的分布位置、大小与距离来计算有效的竞争木，并不是传统意义上的全部竞争木；本研究提出用树冠叠加指数来表示林木与周围树木的树冠竞争情况，并采用等树冠投影面积法把树冠分为5级，这样计算的树冠叠加指数更加与现实林分相符。6、本研究基于乘除法的思想，用多样性混交度、聚集指数、竞争指数和树冠叠加指数构建了天然次生林择伐空间优化模型，设计了10个与林学意义相一致的约束条件，并采用0-1整数规划的思路，在LINGO9.0软件中使用了隐枚举法对目标函数求得最优解。7、以M702标准地为应用实例，具体计算出了每株采伐木，经过择伐后，目标函数值按模型设计的要求发生了极大的改变，增加了5倍多，说明了最后这个解的优良性，满足了设计的要求。

For example, because of the lack of curriculum inspection system, the aim of curriculum averts from the aim of student\'s cultivation, the settlement of curriculum tends to copy or simplify the settlement of undergraduate curriculum, the contents of the curriculum can hardly follow the steps of the times etc. Also, because of different apprehension about the function of educational research in improving teachers professional development, many faculties\' ideas seems to be behind the requirement of steps of the times. Their value inclination "lay much importance upon science, theory, knowledge and look down upon technology, practice, ability" is exercising potential influence on students\' value tendency in their study.

比如，由于缺乏对课程设置的审议制度，导致高职院校的课程设置倾向照搬或者压缩本科院校的相关课程，课程目标偏离高职教育人才培养的目标，课程内容跟不上技术发展的步伐等；由于教师对教育科研在教师专业发展中的作用认识不一，不少教师的理念往往滞后于时代发展的要求，不同程度上呈现出&重理论轻实践&、&重科学轻技术&和&重知识轻技能&的价值倾向，潜移默化地影响到学生在学习过程中的价值取向。

The paper coalesces these three theories and posits three assumptions to the determinants of subsistence of NATO after the Cold War, that is: 1, The U.S.A as a superpower around the world is the leader of the alliance. The development of NATO accords with American interests. The U.S.A supports the existence of NATO. 2, The alliance furnished the members with mutual security interests and their different needs of self-interests. Most of the leaguers identify with NATO's status and function toward European security. 3, Each of the members has its specific national interests goals. The conformity of their crucial aims affects the situation of stability and development of the alliance. It will be a positive effect to the alliance when they are accorded and it will be a negative one when they are diverged.

本文结合了这几个主要流派在联盟理论方面的卓越部分，在此基础上，对北约联盟在冷战后存续的决定性因素作出了自己的理论假说并对其进行了论证，即：1、美国这个超级大国是北约的主导国，北约的继续发展符合美国利益，美国支持北约的存续；2、北约组织为其成员国提供了可以分享的共同安全利益以及各自不同的利益需求，其绝大多数成员国认同该联盟在欧洲安全中所扮演的的角色及其地位和作用；3、北约各成员国各自特殊利益目标的一致性与否影响北约的存续，即，当成员国特殊利益目标一致时，其行动方向一致，对北约的存续产生正面作用；当不一致或发生冲突时，其行动方向歧异，对北约的发展产生负面作用。

ACCORD was designed differently and for a different purpose, and showed that rapid and very intensively forcing the HbA1c down to the normal range, and continuing to try very hard even in individuals who were not achieving target, carries an increased risk of hypos and deaths. We know that the extra deaths appeared to be mainly CV,, but we do not yet know that it definitely was previous hypos that were responsible - although data from VADT would support this interim potential explanation.

ACCORD试验的设计不同于以往的试验，研究目的也不同，HbA1c下降非常迅速，目标也很严格，在那些难以达到目标的患者中仍然努力地强化达标，从而导致了低血糖风险和死亡率的增加，额外增加的死亡主要源于心血管事件而非低血糖昏迷，对此我们尚不明了低血糖事件是否对于死亡率的增加有作用，虽然VADT试验结果支持这样的推论。
