质量作用

For example, the base for public opinion development is not stable and qualitative; the government is impercipient on its significances; there is no agreeable circumstances and integrated supervision system; and at the same time some negative effects come to the surface.

但是，我们也应该看到，公众舆论在我国政治文明建设进程中的发展也存在诸多的矛盾和问题，例如由于多方面的原因，公众舆论发展缺乏稳定和高质量的基础；我国政治系统中对公众舆论的重要性认识不足，没有形成完善的舆论引导和调控机制以及良好的舆论监督环境；公众舆论发展的一些负面作用也开始暴露出来。

Increased demand in the community and the massive expansion of higher education under the dual function, both contradiction and the adaptation gap above the existing degree type, the talented person raise pattern and the society needed gradually revealed; degree structure in the rank and the type, distribution of degree conferred institutes and degree quantity proportion are all imbalance; the unit of degree awards too numerous disorderly and the degree awards the population to increasable day by day, the original verification principle and the means lack of operational in reference; the degree quality assurance and monitoring system is to be established.

在社会需求增加和高等教育大规模扩张的双重作用下，我国现有学位类型和人才培养模式与社会需求间的矛盾和适应缺口逐渐显露；学位结构在学位等级、学位类型、学位点布局和学位数量比例等方面存在不同程度的失衡；学位授予单位日益庞杂和学位授予人数日益增多，原有的审核原则和办法缺乏操作性和参照性；学位质量保障与监控体系也亟待建立。

In this paper,the effect of the compound stress of Cu,Cd,Pb,Zn and As on the growth and the accumulation and the distribution of heavy metals in Juncus Effuses is researched by using soil cultures method.

通过物理模型实验对海岸波浪作用下污染物运动特性进行了分析，重点分析了质量输移流、沿岸流、沿岸流不稳定运动及破波带内旋涡运动等海岸水动力因素的影响。

With Yangtze delta tidal flat as an example, through the analysis on the magnetic characteristics of tidal flat sediment and the study on the space distribution of heavy metal elements, this thesis discussed the impact to Shanghai sea bank brought by heavy intensity development, and the interrelation between sediment power effect and heavy metal pollution space distribution. Utilizing the advantage of artificial intelligence neural network, in conjunction with environmental chemical analysis, from the angle of view of sediment magnetic characteristics, it analyzed the connection mechanism between magnetic mines and heavy metal element within tidal sediments, and built a quantitative magnetical diagnosis model, in attempt to calculating the tidal heavy metal pollution status from the magnetic measurement data of sediments and assess it's impact to the environment.
