Based on the findings and some advanced experience from developed countries, this paper gives out some policy advice. For instance, the central government should set the elementary education fiscal investment as a fixed proportion to local GDP; the provinces with population outflow should get some inter-governmental grants to encourage the development of local elementary education. In the trend of fiscal decentralization, this paper is trying to figure out a trade off between the efficiency and the fairness of elementary education.

在此基础上，本文通过借鉴发达国家对于基础教育财政投入的经验，提出了设定基础教育财政占地方GDP的比例，根据人口流动特征对人口流出省进行基础教育经费补贴等政策性建议，以期能够探索性地提出一些政策思路，力图在教育财政分权的过程中，在基础教育的办学效率和公平之间找到一种更为有效的平衡。

对比分析了多种硫沉积防治方法，防治的关键在于溶硫剂的合理选择，通过溶硫剂优选室内评价实验研究筛选出三乙烯四胺、二乙烯三胺和乙醇胺等三种单剂，按照不同的比例与现场使用的防冻剂乙二醇进行复配，最终形成了适合川东地区高含硫气井的溶硫剂LJ-1合理配方，性能评价实验表明溶硫剂LJ-1溶硫速率快、溶解度高、腐蚀小。

Cluster analysis and two-way contingency table analysis were used to study the ontogenetic variations in the feeding habits of plaice, and the results showed that the feeding activity of plaice did not vary significantly among 7 size classes within the size between 51 mm and 370 mm, but ontogenetic variations were found in the diet composition. In the size class 200 mm, plaice mainly fed on Decapoda and fishes.
