Caudatum was studied. 0.05 mg/L could be the critical mass concn. of P. caudatum fitting to Cu(superscript 2+).Below this concn., the polysaccharide content in P. caudatum was increased in a small range with the increment of mass concn. of Cu(superscript 2+),then the growth and propagation of P. caudatum was strengthened and above this concn., the polysaccharide content was decreased significantly with the increment of mass concn. of Cu(superscript 2+), then the growth and propagation of P. caudatum began to be restrained obviously and the poison was more obvious when the concn.

结果］0.05 mg/L可能是大草履虫适应Cu(上标 2+)的临界质量浓度，低于此浓度时，大草履虫体内的多糖含量随着Cu(上标 2+)质量浓度增大而呈现小幅度的增高，大草履虫的生长繁殖得到增强，高于此浓度时，大草履虫体内的多糖含量随着Cu(上标 2+)质量浓度增大而显著地降低，大草履虫生长繁殖开始明显受到抑制，且浓度越高受毒害越明显。

In the DQ/EG homogeneous solution, the enhanced emissive CIDEP signal of the neutral durosemiquinone radical DQH(superscript ﹒) was observed. When the DQ/EG solution with pH=9 or DQ/EG/TX-100/H2O micelle system was photolyzed, the CIDEP signal of the duroquinone anion radical DQ(superscript ﹒- was obtained. When the DQ/EG solution with pH=2.5 was irradiated, the CIDEP signal of DQH(superscript ﹒) appeared.

在光解均相DQ/EG溶液时，观察到了以增强发射的中性杜半醌自由基DQH(上标﹒的CIDEP信号；在碱性环境下(pH=9)和TX-100胶束环境下光解DQ/EG体系时得到杜醌负离子自由基DQ(上标-﹒的CIDEP信号；在酸性环境下(pH=2.5)光解DQ/EG体系时，出现的又是中性杜半醌自由基DQH(上标﹒的CIDEP信号。

A good agreement for the first system was obtained. Thermodynamics predicted the existence of hexahydrite MgSO46H2O which was absence in our measurements.

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。

With diluted anaerobically pretreated wastewater from a pig farm and Spirodela oligorrhiza, TN, NH(superscript + subscript 4)-N and NO(superscript – subscript x)-N removal pathways in shallow-water duckweed-based wastewater treatment systems were studied in summer and winter.
