1.From August 15 to September 2,2005,the contents of colloidal trace metal(1kD~1μm)Fe,Mn,Cu,Zn,Pb and Cd and the content variation of suspended solids(SS),plankton and colloidal organic carbon(COC)background indexes in Taihu Lake were observed under different wind-wave conditions.
2005年8月15日~9月2日,观测了不同风浪条件下太湖水体中胶体态(1kD~1μm)Fe、Mn、Cu、Zn、Pb和Cd等痕量金属的含量以及悬浮物(SS)、浮游生物和胶体有机碳(COC)等背景指标的含量变化.收藏指正
2.Auxiliary SJT-B is a 10% phosphorosilicate colloidal solution,containing Na+ and K+,SiO2-3 and PO3-4,and pentavalent polyphosphorosilicate chain anion formed from activated SiO23 and PO3-4 and the chain anion can bind Ca2+ and Mg2+,thus inhibiting scaling and metal corrosion.
助剂SJT-B是10%的磷硅酸盐胶体溶液,含有Na+和K+、SiO32-和PO43-等离子,在活化状态下一部分SiO32-和PO43-生成具5个负电荷的聚磷硅酸根链状阴离子,后者可结合Ca2+、Mg2+而形成纳米磷硅酸盐胶态粒子,避免结垢并防止金属腐蚀。收藏指正
3.The process is very similar to that used to electroplate aprecious metal onto an object except that the absence of a receiving object at another electrode causes the silver to remain in a colloidal suspension in the water.
这个工艺过程与将稀有金属电镀到物体上非常相似,只是另一个电极上没有接受物体而使银保留在水中的胶状悬浮液上.收藏指正
4.An HPAM/metal ion/phenolic resin colloidal dispersion gel(CDG) is outlined for its basic composion, formation conditions and performance properties; the features(injection pressure, volume, plug structure, and technologic aspects) of CDG flood design at well net J 145 of fault block MA 21, Hejian, central Hebei, are described and an analysis of the results of the pilot test on CDG flood at well net J 145 is given.
报道了由HPAM和金属离子、酚醛树脂组成的胶态分散凝胶 (CDG)的基本组成、形成条件和性能参数 ,介绍了冀中河间马 2 1断块间 145井组CDG调驱设计要点 (注入压力 ,段塞组成、注入量及注入工艺 )及实施情况 ,分析了该井组CDG调驱结果。收藏指正
