Researcher who held the post of the media literacy lecture for the past three years, discover through the interaction with the teacher who join the seminar or the teaching team who need the counseling, it's not easily to implement media literacy in the school, lay in the teacher to be insufficient regarding the media elementary knowledge, causes to be unable independently to design the teaching activity, however in the market although had few publications to be allowed to instruct the media literacy teaching, but in the teaching activity often needed to use the massive media model, those had to collect by the teacher voluntarily, moreover most of these curricula taken the independent teaching, didn't intergrade and coordinated with the existing curriculum, therefore could have the problem in the teaching time.

研究者以三年来担任媒体素养研习讲师，与参加研习的教师和寻求辅导的教学团队互动的经验中发现，不易在教学现场实践媒体素养教育的原因，在於教师个人对於媒体的知识基模不足，以致於无法自行设计教学活动，而坊间虽有极少数的出版品指导媒体素养教学，但教学活动中往往需要用到大量媒体范例，必须靠教师自行搜集，而且这些课程多采独立教学，并非配合现有学科进行融入教学，所以会有教学时间的困难。

可在钻起过程中起到休整井壁的作用，使井眼轨迹尽量达到理想状态，防止出现狗腿现象。特别是在起钻过程中，往往由于井眼缩径等原因导致起钻困难，此时，该稳定器上的倒划眼齿可起到切削作用，以消除缩径等现象，从而为钻井节省大量时间和费用。

The main results were summarized as follows: 1 With the increase of cooling rate, full recrystallization during cooling became difficult to take place and the decrease in dislocation density became slow so that dislocation density in austenite remains higher before phase transformation occurred. 2 Compared with undeformed samples, the CCT diagram under deform conditions has a similar shape, but its position shifts leftwards.
