It was proved by IR spectroscopy that Zn2+ and hydrolyzed ion were chelated with polysilicic acid to produce the polymer of zinc-silicon. The reaction was not the simple physical blending,but the chemical reaction forming the inorganic polymer with special structure.

红外光谱证实了PZSS中Zn2+及水解Zn2+离子可与共存的聚硅酸起螯合反应生成锌硅聚合物，聚硅酸与Zn2+反应并不是单纯的物理混合加成作用，而是形成了具有特殊结构的无机高分子的化学反应，这种新型絮凝剂所具有的优良絮凝特性是由各物质间以化学作用为主的物理化学因素共同作用的结果。

It was proved by IR spectroscopy that Zn(superscript 2+) and hydrolyzed ion were chelated with polysilicic acid to produce the polymer of zinc-silicon. The reaction was not the simple physical blending, but the chemical reaction forming the inorganic polymer with special structure. The better flocculating efficiency was resulted mainly from the chemical and physico-chemical factors among the components.

红外光谱证实了PZSS中Zn(上标 2+)及水解Zn(上标 2+)离子可与共存的聚硅酸起螯合反应生成锌硅聚合物，聚硅酸与Zn(上标 2+)反应并不是单纯的物理混合加成作用，而是形成了具有特殊结构的无机高分子的化学反应，这种新型絮凝剂所具有的优良絮凝特性是由各物质间以化学作用为主的物理化学因素共同作用的结果。

Physical chemistry index was determined by potentiometric method, oven drying method, Kjeldah method and organic matter.

同时以pH、水分、全氮和有机质等测定堆肥的物理化学指标。

In the preformulation studies, UV absorption characteristics, solubility and stability of the drug in the different media were determined, the physico -chemical compatibility between the drug and nine kinds of excipients was observed using DSC analysis.

在处方前研究中，对盐酸尼卡地平的紫外吸收特性、不同介质中的溶解度和稳定性进行了测定，并利用DSC法考察了该药物与九种辅料（EC，HPMC，PVP，PEG6000，MCC，乳糖，淀粉，硬脂酸镁，SLS等）间的物理化学相容性。

The sedimentation analysis method was used for measuring the sand content of settleable solid in wastewater.

应用物理化学分析中的沉降分析法对污水水体内可沉固体中含砂率进行测定。

A mode of the directionally growth of PAn on the surface of NaFe〓P〓rod-like particle was suggested. Some of aniline molecules in the reactants are fixed on the surface of skutterudite particles before the beginning of the polymerization. Other aniline molecules link with the aniline molecules fixed on the surface of skutterudite and form liner chains when the initiater is added into the reactants.

提出了聚苯胺在棒状方钴矿NaFe〓P〓材料表面定向生长的物理化学模型：在表面配位键的作用下方钴矿晶须表面首先附着了一层苯胺单体，在引发剂的作用下溶液中的苯胺分子在这层单体上定向聚合，形成了定向聚苯胺线性分子。

Based on the case study of Dongying Basin, we evaluated quantitatively the contribution of illitization of smectite to the geopressure during diagensis processes.
