Deoxy-hemoglobin of Bar-Headed Goose was prepared with Na2S2O4 as reducing agent.The single crystals were obtained from polyethylene glycol solution 6000 at pH 7.2, 0.05mool/L phosphate buffer, protein 20mg/ml. Using the hanging drop methed.

报导了以Na2S2O4为还原剂制备脱氧血红蛋白，并以聚乙二醇溶液为沉淀剂，在pH7.2，蛋白浓度20mg／ml条件下培养出适合于X射线分析用的斑头雁脱氧血红蛋白晶体，经X射线平面探测仪收集衍射强度数据和处理。

Benzoyl chloride was treated with potassium selenocyanate in dichioromethane by using polyethylene glycal-400 as the solid-liquid phase transfer catalyst to yield the corresponding benzoyl isoselenocyanate. This intermediate did not need to be isolated and directly reacted with arylamines, affording the N-benzoyl-N'-arylselenoureas 2a~2p. These compounds were characterized by IR, 1H NMR spectra and elemental analysis and the single crystal structure of 2k has been confirmed by X-ray crystallographic analysis.

以PEG-400为固液相转移催化剂，通过苯甲酰氯与硒氰酸钾反应合成了中间体苯甲酰基异硒氰酸酯，该中间体不需分离，直接与芳胺反应，得到N-苯甲酰基－N'-芳基硒脲(2a~2p)，这些化合物用1H NMR，IR及元素分析进行了表徵，并用X射线单晶衍射确定了化合物2k的单晶结构。

The reaction mechanism, by-reaction inhibition, effect of initiator, and monomer on grafted products are studied extensively. Polyethylene grafted with maleic anhydride, as the hot melt adhesive for the aluminum-plastics compound pipe, is also studied as a goal for engineering application.

对反应挤出接枝体系进行了热分析，确定了合理的反应挤出工艺条件：用红外光谱和化学滴定的方法分别对接枝结构和接枝率作了定性表征和定量测定；对三种反应挤出体系的反应机理和副反应的抑制，以及引发剂、单体对接枝产物的影响进行了深入系统地研究；对PE接枝MAH作为铝塑复合管的热熔胶进行了工程化应用研究。
