查询词典 keep back

This article uses the literature material law, the cut-and-try method, visits the survey procedure, the mathematical method of average and so on, in the back more -like high jump teaching, the use skill migration rule, begins from the interesting teaching to create the thin raw white silk and the design sports game, and utilizes it in the back -like high jump experiment teaching, through the teaching discovered utilizes the game teaching method in the back more -like high jump teaching, not only is advantageous to the student to complete technical movement grasping, moreover is advantageous to the change former back -like high jump teaching arid tasteless aspect, thus enhances the teaching effect.

本文采用文献资料法、实验法、走访调查法、数理统计法等，在背越式跳高教学中，利用技能迁移规律，从趣味性教学着手创编与设计体育游戏，并把它运用于背越式跳高实验教学中，通过教学发现在背越式跳高教学中运用游戏教学手段，不仅有利于学生对完整技术动作的掌握，而且有利于改变以往背越式跳高教学枯燥乏味的局面，从而提高教学效果。

Plastic should lower 3 steps, because plastic is a step to add melt resin material to cyclinder , Higher stick of resin material ,higher screw back pressure. Screw speed differs depending on decomposing temperature of resin material ,Higher screw speed ,Higher trim force of resin, higher cyclinder temperature. Some resin material may decomposes so it set screw speed in mid-speed such as 45-75%, In plastic step setting screw back pressure is very important, Higher screw back pressure ,higher quality of product screw back pressure make resin structure order, Molding product is beautiful and volume stable.

再复杂的熔胶旋转过程最多不会超过三段，因为熔胶本身就是存在于把胶熔进料筒的过程，如果原料粘度大，熔胶压力则大，但速度则应取决于原料的分解温度，熔胶速度越快，原料中的剪切力则会越大，料管温度则越高，局部原料产生分解的可能性则会越大，故一般熔胶会采用中速为宜，如45%-75%，熔胶同时会碰到一个比较重要的环节，那就是背压的使用，产品精度要求越大，背压的使用则更大，背压可使原料分子间结构更紧密，成型出的产品则尺寸更稳定，外观越好。

My 宝宝 seven months ago, do not sweat at night and sometimes the back of the head, sometimes sweating is not many, nearly a month since the increase in sweating during the day and sometimes the back of the head without cases of hot sweating, especially at night,, then one together one out together, did they re-sweating, night terrors mix,(I am on the night in the back of his head out of the yard will also 2 months into the Khan, and now better), but I have children and other children than is the spirit of good during the day also played energetically, that tempers big points, 7 pm at the meeting on two days after the calcium to a medical examination, to do the trace elements in check, all is not missing, do not know why and I sweat like the back of the head, but so many, I think is not normal, ask people around you, Why is this?

我的宝宝7个月以前，后脑勺有时候夜里不出汗，有时候出汗也不多，近一个月以来出汗增加，白天有时候后脑勺在不热的情况下也出汗，夜里尤甚，，一拢接一拢的出，干了后又再出汗，拌夜惊，（我夜里后脑勺在月子里也出了将进2个月的汗，现在好了），但我宝宝在和别的宝宝比起来算是精神好的，白天也玩的起劲，就是觉得脾气大点，7个月时在补了两天钙后，去体检，做了微量元素检查，全部不缺，不知道为什么和我一样都是后脑勺出汗，而且出这么多，我觉已经不正常了，请教各位过来人，，这是为什么？
