Abstract:对不同的培养条件下茶愈伤组织生长及其茶氨酸累积情况进行了研究。结果表明，激素ＩＡＡ和６－ＢＡ结合作用时，存在着相互效应，其中以ＩＡＡ２ｍｇ／Ｌ和６－ＢＡ４ｍｇ／Ｌ时对茶氨酸累积最有利。不同碳源对于愈伤组织生长和茶氨酸积累的影响相近。增加糖浓度有利于次生代谢物的累积，茶氨酸组织的最适培养温度和茶氨酸累积温度都是２５℃。暗培养比有光培养更有利于茶氨酸的累积。茶氨酸的累积曲线与愈伤组织生长密切相关，调节培养基成分使茶氨酸在茶愈伤组织（干质量）中的含量达到了２０１．６ｍｇ／ｇ．

Abstract:以６０Ｃｏ的ｒ射线为诱变剂，核黄素合成途径的中间产物的结构类似物为“筛子”，筛选了阿舒假囊酵母（Ｅｒｅｍｏｔｈｅｃｉｕｍａｓｈｂｙｉ）的四种抗性突变株：杀结核菌素抗性突变株（Ｔｕｂｒ）、２－脱氧葡萄糖抗性突变株（２－ＤＧｒ）、８－氮杂鸟嘌呤（８－ＡＧｒ）和抗残液突变株。杀结核菌素抗性突变株Ｔ３０的摇瓶核黄素产量由出发菌的２．５～２．８ｍｇ／Ｌ提高并稳定在３．５ｍｇ／Ｌ以上，经初步优化（培养基配方）后，稳定在５．４ｇ／Ｌ以上。

Abstract:初步研究了面包酵母胞内海藻糖含量对其耐贮存力的影响，探讨了提高鲜酵母胞内海藻糖含量的培养措施。研究结果表明，海藻糖含量越高，面包酵母的耐贮存力越强。采用提高海藻糖含量的培养技术进行流加培养，发酵结束时面包酵母中海藻糖含量从９．７ｍｇ／ｇ提高到１９ｍｇ／ｇ．４℃贮存１８ｄ后，面包酵母的发酵活力由１１７０ｍｌ变为１０４０ｍｌ（仅下降了１１％），表现出较优的耐贮存力。

Abstract:提出了用“Ａ＋Ｂ”保鲜剂在常温下保鲜无锡水蜜桃的方法，并与其他保鲜剂作了比较。具有简单易行，投资小，见效快等特点。水蜜桃保鲜期为１０ｄ左右，总损耗率小于２０％．

Abstract:淀粉质基料夹心香肠的热处理时间以传热试验、质构试验和微生物学试验为基础确定。试验表明，经适当乳化处理的，以预糊化马铃薯粉、玉米淀粉、精炼油和水为主体的夹心料，在８０℃的水中蒸煮时，传热速率较纯肉馅料的快。由此种夹心料与肉馅用天然肠衣灌制成的夹心肠的传热速率介于两者之间。通过质构试验发现，夹心料质构在以上热处理条件下的热定型时间约为５０ｍｉｎ．

Abstract:连杆机构输出构件作往复摆动的摆角受到许用传动角［μ］的严格限制。本文中提出一种能获得大摆角的齿轮－连杆机构。它是在Ｋ＝１的曲柄摇杆机构上装载一对传动比为ｉ３的齿轮的组合机构，其输出齿轮作往复摆动，摆角可接近（１－ｉ３）（１８０－２［μ］）．当［μ］＝４０°，ｉ３＝－４时，摆角可接近５００°．故此机构增大摆角的优越性十分明显。文中还研究了此机构的设计计算方法和参数的选择规则并附有设计计算示例。
