First , the author confirms that there is not significant relation between fund return and size as well as investment style by examining the data of closed - end funds . it is also proved that the evaluation method is feasible by evaluating the closed - end funds and open - end funds in china respectively . the author compares risk - return character between closed - end funds and open - end funds and the results show open - end funds " performance is not better than that of closed - end funds according to their risk - return character 首先用封闭式基金的数据验证了基金的收益与基金规模、投资风格并无显著关系，因此本文暂时不分规模、风格进行评价；然后用本文建立的评价系统分别评价开放式基金和封闭式基金，证明方法是切实可行的；最后就开放式基金和封闭式基金的风险收益特征进行了比较，结果显示开放式基金并不优于封闭式基金。
But in experiment ii , the obtained result of measurement and examination is not better than control group 。 conclusion : mixed animo acids can be safely applyed to vessel cryopreservation instead of calf serum 。 the effect of the groups of the rapid freezing method is not better than the groups of the rate - controled slow freezing 而实验ii的血管其内皮结构不清晰，内皮细胞超微结构变化较大。结论：复方氨基酸可代替胎牛血清用于血管的深低温保存.速冻降温方式对血管深低温保存效果不及慢冻降温方式。
The reason why the return to investment fund is not better than to the average of the market is : the competition of investment funds is severity ; the invest idea and style is multiplicity ; the capability of selecting the opportunity of security market is not notability and the ability of stock selecting emphasize the risk decentralization , not the income 基金组合投资绩效不理想原因如下：我国证券市场的竞争日益加剧，且基金的资金量庞大，试图获得超额收益已越来越难；基金的投资理念也由积极投资一统天下转向投资风格多样化；从基金的运作来看，基金的市场时间规划效果不明显，股票选择侧重于风险分散。
Nonlinear elastic model can stimulate the hardening part before peak value , but the stimulation to softening part is not satisfying . elasto - plastic model can basically stimulate the full course of loess deformation , but the stimulation to softening part is not better than that of hardening part . elasto - plastic damage model is the best model of stimulating loess deformation , and the breakage degree during the loess deformation can be estimated based on magnitude and variety of the damage 非线性模型可以模拟峰值前的硬化部分，但不能很好模拟软化段较陡的降落；弹塑性模型基本能够模拟土体变形的全过程，但对软化段的模拟有一定偏离不如硬化段好；弹塑性损伤模型模拟土的变形特性效果最好，可以对土的西安理工大学硕士学位论文一变形全过程较好的模拟，并能根据损伤变量的大小和变化定量评价土体在不同变形阶段的破坏程度。
Based on 185 listed companies with competitive shareholding structure in china , we find that the shareholding ratio by the 5 larger shareholders is related with each other significantly , the ratio of share held by the top 1 , top 2 and top 5 large shareholder is positive related to performance , but the performance of sample companies is not better than the other firms of the samples 对我国185家竞争性股权结构公司的分析表明，前五大股东持股比例之间呈现出依次显著性的正相关关系，第一、第二和第五大股东持股比例与公司业绩显著正相关，但这类上市公司并没有比非竞争性股权结构公司具有更好的业绩。
This made my life better than sociable , for when i began to regret the want of conversation , i would ask my self whether thus conversing mutually with my own thoughts , and , as i hope i may say , with even god himself by ejaculations , was not better than the utmost enjoyment of humane society in the world 这样，我觉得我现在的生活比有交际的生活还要好。因为，每当我抱怨没有人可以交谈时，我便责问自己，同自己的思想交谈，并且，我想我可以说，通过祷告同上帝交谈，不是比世界上人类社会中的交际更好吗？
In harnessed watershed , a is smaller and b is bigger , but they are contrary in no - harnessed watershed . the flood peak volume modulus and sediment transport modulus is also power function relationship . but parameter a and b is different largely in different watershed and the relativity is not well than relationship between runoff depth and sediment transport modulus 参数a 、 b可以反映流域有无治理的差异，参数a在有治理或部分治理的流域内均小于无治理流域；参数b在有治理流域内则较无治理流域偏大；流域次降雨洪峰流量模数与输沙模数也为幂函数关系，但参数a 、 b在不同流域之间差别较大，其相关性不如径流深与输沙模数关系好。
In the course of western development , developing middle and western regions electronic business is not better than the eastern developed regions , but the electronic business should be orientated to communicate and spread the enterprises information , promote the enterprises " quality , advance the adjustment of industry structures , improve the balance of regions " economic development , enhance the enterprises " managerial ideas and means 论文首先简要介绍电子商务的定义、特点、分类以及在经济活动中的作用。随后根据国外发展资料，和近几年东部地区几个城市的电子商务发展数据简述电子商务给西部经济带来的机遇和挑战；接下来分析西部电子商务发展存在的问题；最后讨论推动西部地区电子商务发展的若干对策。
This paper discuss the performance and portfolio strategy about investment fund through the regression analysis of scl based on capital market theory . the results indicate that the extra rate of return to investment fund is not better than to the average of the market 本文根据资本市场理论，通过应用统计分析、事后证券组合特征曲线的回归分析以及投资组合分析，对证券投资基金的投资绩效以及投资组合策略进行实证研究。结果表明，投资基金绝大部分都未获得超出市场平均水平的超额收益率，投资绩效不明显。
