The activitys of Super Oxide Dismutase, peroxidase and Multiple Displacement Amplification of Ceratophyllum demersum L raised rapidly in the late of experiment, and the maximum value of MDA of Ceratophyllum demersum L in the eutrophic condition was 5 time higher than that in the medium nutritional condition, implied that Ceratophyllum demersum L has been stressed in the middle nutritional condition.

金鱼藻超氧歧化酶活性、过氧化物酶活性和丙二醛含量在试验后期上升速度加快，且富营养水平下金鱼藻MDA质量分数的最大值是中营养水平下最大值的5倍，表明在中营养水平下金鱼藻已经受到明显胁迫，而在富营养水平下受到胁迫更为显著。

Using panel data of listed companies, this paper analyzes it with a quantile regression approach, then draws a conclusion: the share structure and the capability of emerging interior resources effect the capital structure changeably with the different quantiles respectively. That is, for those conditions with low asset-liability ratio, the sign is positive, on the contrary, the sign is negative.

为此本文尝试着将分位数回归理论引入到回归模型中，通过对我国上市公司的相关数据进行分位数回归分析后发现，不同资产负债率水平下，企业股权结构、企业产生内部资源的能力对资本结构的影响效果不同：低负债率水平下，两者均与债务水平正相关；而高负债率水平下，又均与债务水平负相关。

Expression of Caspase-3 and bcl-2 protein In E20 cerebral cortex, the expression of cleaved Caspase-3 in the encephalocoele group are higher than that in control group, and the expression of bcl-2 in the encephalocoele group are lower than that in control group. These findings were consistent with the results of the western blot analysis in E14 Brain.

Also, it analyzed the similarity and difference in the relation between income satisfaction and marriage nowadays in China: among those who have been married, the average income satisfaction degree is obviously higher than those who are not married; among them, males have comparatively higher average income satisfaction, which indicates that men obtain more eudemonia factors from marriage. In China, because of the economic and mental difference between the city and the country, the relation between income satisfaction degree and marriage has manifested some diversity, mainly as follows: 1. those who divorced in rural area has the lowest average income satisfaction among all the different marrital statuses; those who divorced in urban area has the intermediate average income satisfaction.

在我国，由于城市和农村在思想上的差异和经济上的差距，收入满足度与婚姻之间的关系呈现一定的差异性，主要表现在：1、农村离婚人士的平均收入满足度在农村各种婚姻状况中处于最低水平；(来源：ABC论70文网www.abclunwen.com)城市离婚人士的平均收入满足度在城市所有婚姻状况中处于中等水平。2、城市再婚人士的平均收入满足度在城市所有婚姻状况中处于最高水平；农村再婚人士的平均收入满足度在农村所有婚姻状况中处于中等水平。3、城市未婚女性的平均收入满足度高于城市未婚男性；农村未婚女性与农村未婚男性的平均收入满足度相同。4、在农村的收入满足度调查问卷中同居一项的样本数为0。
