“油气田勘探部署”基于“理论-实例”的教学内容优化

"油气田勘探部署"是一门理论与实践紧密结合的课程,应在原课程教学内容的基础上,增加实例的教学内容。经过对准噶尔盆地多年的勘探开发积累了丰富的勘探成果与勘探经验,克拉玛依校区依托地理优势将新疆油田公司在准噶尔盆地典型的勘探成果纳入课程实例体系,将理论与实例充分融合,为克拉玛依校区高等工程示范基地新工科建设开启有益的教学探索。

3种添加配方奶的喂养方式对促进母乳喂养的影响

目的:探讨3种添加配方奶的喂养方式对促进母乳喂养的影响。方法:将出生3天内的300例剖宫产术后有添加配方奶指征的新生儿随机分为3组,观察(100例)新生儿用母乳喂养促进器喂养,对照组1(100例)新生儿用奶瓶喂养,对照组2(100例)新生儿用小勺喂养;比较新生儿产生乳头错觉的情况、产妇母乳充盈的时间、发生产妇奶胀的情况。结果:观察组新生儿产生乳头错觉3例、产妇母乳充盈的时间术后42小时、产妇奶胀4例;对照组1新生儿产生乳头错觉32例、产妇母乳充盈的时间术后66小时,产妇奶胀38例;对照组2新生儿产生乳头错觉84例、产妇母乳充盈的时间术后72小时,产妇奶胀78例。结论:用母乳喂养促进器喂养明显优于用奶瓶喂养及小勺喂养,新生儿产生乳头错觉极低,母乳充盈的时间较短,产奶较快,产妇奶胀的发生率低(P<0.01),可增强产妇母乳喂养的信心,有效地促进母乳喂养的成功。

Dual Active Bridge Converter as Gyrator
