简介:摘要文章以教材中的根号下a2=a(a≥0)这个知识点为基点对教材的安排和设计进行了讨论,旨在倡导教师在教学中挖掘、质疑、发现教材各知识点的设计意图与横纵联系,以及在教学中针对不同的学生进行教学设计,使学生能更好地接受知识,提升他们学习的思维空间。
简介:摘要目的探讨冻干制剂乙型脑炎减毒活疫苗和液体制剂23价肺炎球菌多糖疫苗0~2 ℃条件下存放对其效价的影响。方法将冻干制剂乙型脑炎减毒活疫苗和液体制剂23价肺炎球菌多糖疫苗存放于0~2 ℃条件下一定时间后,与存放于2~8 ℃规定条件的制品进行疫苗效价的比较。结果1人份和5人份乙型脑炎减毒活疫苗在0~2 ℃条件下分别存放17 h 20 min和18 h 55 min,病毒滴度均符合5.7~7.1 lgPFU/ml的质量标准,且与存放于2~8 ℃规定条件的同批次疫苗比较,t值分别为0.26和0.28,P值均大于0.05,差异无统计学意义;23价肺炎球菌多糖疫苗在0~2 ℃条件下存放21 h 50 min,23个型别的多糖含量均符合35~65 μg/ml的质量标准,且与存放于2~8 ℃规定条件的同批次疫苗比较,t值为0.01~2.25,P值均大于0.05,差异无统计学意义。结论冻干制剂乙型脑炎减毒活疫苗和液体制剂23价肺炎球菌多糖疫苗存放在0~2 ℃条件下的一定时间内,疫苗效价仍符合质量标准。
