Laminate flooring can be installed over floors like wood, tile, vinyl or linoleum because most of them are floating which means they do not fasten directly to the subfloor.

地板可以安装在像木地板、瓷砖、乙烯基或油毡因为他们大多不佩戴浮动即直接向底板。

Molecularly imprinted polymers of sulfamethazine(SM 2 ) were prepared with silica gel as a sacrificial material, methacrylic acid and 4 vinylpyridine(4 Vp) as functional monomers, glycol dimethacrylate as crosslinker. The polymer properties were investigated by static adsorption experiments. Scatchard analysis shows that the adsorption ability of MAA MIP is superior to that of 4 Vp MIP. The dissociation constant of MAA MIP is 9 59×10 -4 mol/L. The value of apparent binding a...

以磺胺二甲嘧啶为模板分子，分别用甲基丙烯酸和4乙烯基吡啶为功能单体，二甲基丙烯酸乙二醇酯为交联剂，采用牺牲硅胶法合成了磺胺分子印迹聚合物，通过静态吸附实验，系统研究了不同单体对聚合物识别性能的影响；Scatchard分析表明，以甲基丙烯酸为单体的聚合物具有较高的吸附能力，其离解常数Kd为959×10-4mol/L，最大表观结合位点数Qmax为3070μmol/g。

Three methods are used to prepare molecular imprinted polymers,which include conventional bulk technique or polymerization with ultraviolet initiated in low temperature and polymerization with silica-gel as sacrificial materials. In the polymerization procedure , Sulfamethazine(SM2)and Sulfisoxazole were used as target template molecules, methacrylic acid and 4-vinylpyridine(4-VP) and acrylamide were selected as functional monomers, ethylene glycol dimethacrylate as crosslinker, azobisisobutyronitrile was used as initator.

主要工作如下：首先，以磺胺异噁唑和磺胺二甲嘧啶为模板，分别以4-乙烯基吡啶，甲基丙烯酸，丙烯酰胺为功能单体，以二甲基丙烯酸乙二醇酯为交联剂，偶氮二异丁腈为引发剂，采用了传统方法(60℃恒温水浴)、牺牲硅胶法及低温紫外光聚合法等三种方法合成了一系列的磺胺类药物印迹聚合物。
