火工品可靠性(或安全性)评估的Bayes方法

对火工品可靠性（或安全性）评估中通常采用的经典方法进行了剖析。介绍了数理统计方法学中近年来兴起的Ｂａｙｅｓ统计推断方法，并给出了此法在火工品二项分布、正态分布情况下，对可靠度评估的应用实例。     

应规范用人单位内部调职行为

用人单位内部调职是指在同一用人单位内,长期性的变更劳动者的工作场所、工作内容的用人单位的行为.长期性的变更是用人单位内部调职的重要特征,并因此与出差区别开来.     

含油污泥固化处理后油的迁移研究

利用紫外分光光度计和索氏抽提器,研究了温度、土壤含水率以及水泥与污泥的不同比例等因素在不同时间对含油污泥固化后油迁移的影响。试验结果表明:对于强度为3.84MPa的污泥固化块,油的迁移量从240h迁移6.8mg变为480h迁移178mg,之后变化较小。在20℃～30℃时,随着温度的增加,迁移量从6.8mg增加到20.6mg,超过30℃以后迁移量的增幅变小。水泥与污泥的比例从1∶0.8增加到1∶1.4,油的迁移量从256mg降到27.2mg,之后未检测到。960h后,迁移量达到348mg,此时土壤中油含量为1.16%,在环境的自净作用下,土壤能完全容纳;强度大于9.56MPa时未检测到油。这表明用固化法处理油田含油污泥是安全可靠的。     

"双主模式"在课程整合中的应用

信息技术与课程整合的实施是强调在各学科的教学过程中积极运用信息技术.大部分学校的实践过程中还是普遍存在着这样那样的误区.将“双主模式“教学设计理论作为信息技术与课程整合的指导思想,体现学生的主体性,发挥教师的主导作用.
