Milk fiber.The influence of pH value,dyeing temperature and neutral electrolytes on percent exhaustion were studied.The dyeing rates and buildingup properties of these dyes were also discussed.The effect of pH value was prominent on percent exhaustion,showing that the electrovalent bond between the dyes and the casein component of the fiber played an important role in the uptake of dyes.The ...

染液pH值、染色温度、元明粉等对上染率的影响，以及这两类染料在牛奶丝上的染色速度和提升性能的研究表明，牛奶丝染色受pH值影响很大，说明染料与酪素蛋白之间的离子键结合对染料上染起重要作用；元明粉在各pH值下对上染率的影响显示，牛奶丝的等电点约为4；酸性染料对牛奶丝的初染率高、初染速度快，但80℃恒温下的上染速度却慢于蚕丝和羊绒；牛奶丝染色对pH值的敏感性大于蚕丝和羊绒，且其酸性染料上的提升力较蚕丝和羊绒差。

银杏的不同器官和组织都能够诱导出愈伤组织来，其中，子叶和胚轴10d左右全部愈伤化，诱导速度和诱导率均最高，根则很难诱导，愈伤组织很少，褐化很快；叶片诱导的愈伤组织，生长慢，褐化也慢，在培养基上保持两三个月而不褐化；胚乳的诱导时间也较长，需要30d左右。

The results were as follows the change of vitamin C content was a "trial apex"-shape curve, higher in young fruit,incrustation and maturation stages, lower in other periods; the total acid content was the highest in young fruit, after that, it decreased rapidly, maintained lower level, and reached lowest when the fruit matured; the total content of soluble sugar inosculated with the fruit development, it was high when the fruit development was quick, and low when the fruit development was slow; before 59 d after anthesis, the reducing sugar content was high in the total content of soluble sugar and after that ,the nonreducing sugar content was high; before 45 d after anthesis, free amino acid content was obviously correlated with protein content, and they inosculated with the fruit development;4559 d after anthesis, free amino acid content increased quickly, and protein content decreased gradually, this was also the most shaping period of the embryo and endosperm.

结果表明，Vc含量呈&三峰&型曲线，幼果时、硬核后和成熟时较高，其他时期较低；有机酸含量以幼果期最高，以后迅速下降并维持较低水平，果实成熟时含量最低；可溶性总糖含量与果实发育状况基本相吻合，果实发育速度快时含量较高，慢时较低；在谢花后59 d以前，可溶性糖以还原糖为主，之后以非还原糖为主；游离氨基酸和蛋白质含量，在谢花后45 d以前两者呈高度相关，且与果实生长速度相吻合，谢花后4559 d是胚和胚乳的主要形成期，此期游离氨基酸含量迅速增加，蛋白质含量持续下降。西北林学院学报21卷第5期张传来等金光杏梅果实发育期间主要营养成分动态变化研究

By use of titration analysis, the thesis investigated various factors such as isocyanate, PE molecular weight, reacting substance molecular ratio, reacting temperature and time etc. influencing upon prepolymerization step. It was found that 2, 4-tolulene diisocyanate and 4, 4'diphenylmethane diisocyanate is more rapidly reacted with PE600 than HDI. With PE molecular weight increasing, the reacting temperature or time should be raised or extended relevantly. Thus PE2000+2HDI pre-polymerization should be better carried out under some catalyst, for example, Triethylene diamine , Dibutyltin dilaurate and Tin octoate were used.

首先采用滴定分析方法对WRPU预聚反应的影响因素进行了研究：芳香族二异氰酸酯TDI、MDI比脂肪族二异氰酸酯HDI反应活性高，其中TDI在反应初始阶段的反应速率比MDI快，不过随着反应的进行，MDI比TDI反应速率加快，这主要是因为TDI分子中的两个-NCO反应活性差异大所致；二元醇分子量越大，反应速度越慢；聚醚二元醇比聚酯二元醇的反应速度快；当分子量超过2000的二元醇与HDI进行预聚反应时，需借助适当的催化剂来加快反应速度，从而使预聚反应能够顺利进行，分别选择DABCO、TOA和DBDTL三种催化剂进行催化反应，发现不同的催化剂，其催化效果相差较大。
