I. 4; Phaedo 97; and a deep thinker like him in his thirty or forty years of public teaching, could hardly have falled to touch on the nature of family relations, for which there is also some positive evidence in the Memorabilia (Mem. i. 2, 51 foll.).

像他那样有着三十乃至四十年从事公众教育经验的深刻思想家，其研究成果也不过刚刚触及到家族关系的某些特征，关于这些倒是在《回忆录》中已有了可信的证据（参见《回忆录》二卷二章51节以下）。

Abstract— Three types of organic pollutants, phenol, phenylamine and dimethyl phthalate as the law of the wastewater treatment were researched with ECS.

In the present paper, the silver-intermediate in development process of PTG material-disilver phthalate (Ag2PA) was prepared by the liquid deposition method, and Ag2PHZ2PA·H2O complex was synthesized successfully by liquid dispersion means using Ag2PA and phthalazine as the reactants. The composition of Ag2PA and Ag2PHZ2PA·H2O was determined by ICP-AES and elemental analysis,...

采用液相沉淀法合成了PTG材料热显成像过程的含银中间体邻苯二甲酸二银(Ag2PA)，并进一步使其与酞嗪络合形成了Ag2PHZ2PA.H2O配合物，通过元素分析、电感耦合等离子体原子发射光谱分析对Ag2PA与Ag2PHZ2PA.H2O配合物的元素组成进行了确定，采用X射线粉末衍射分析、傅里叶变换红外光谱分析以及热分析等方法对Ag2PA与Ag2PHZ2PA.H2O进行了表征，实现了对PTG材料热显成像过程含银中间体的定性分析。
