壳聚糖是一种蕴含丰富的天然高分子化合物,具有抗菌抑菌性、吸附性、无毒、无刺激且价格低廉等特点,应用广泛,但壳聚糖分子量大,难溶于水等特点限制了其应用,因此如何制备低分子量的壳聚糖成为研究热点。选择工业级壳聚糖为研究对象,以此作为原料,采用化学方法,通过协同氧化体系对壳聚糖进行降解,制得低聚壳聚糖。通过五组单因素实验,研究了反应时间,反应温度,n(H_2O_2)/n(壳聚糖)比值,过氧化氢溶液浓度以
摘 要：学生管理工作与思想政治理论课教学是高校大学生思想政治教育系统的重要组成部分，但二者未能实现有效配合，形成整体合力，严重制约了大学生思想政治教育的有效性。要充分认识到二者协调配合的重要性，构建配合模式，找出存在问题，设定相应的工作方案并积极实施，在实际工作配合中应坚持主导性与多样性的统一、理论性与实践性的统一、系统性与针对性的统一原则。 关键词：学生工作； 思想政治理论课； 教学工作 中
