紧密结构

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. But

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。

Whichever way you choose to work-- inductively or deductively-- the intellectual structure should be based on argument, be linked, and be as clear as possible.

不管选择哪一种方式－纳或推演－明的结构应该以论点为基础或与其紧密连结，同时尽可能地清晰。

Whichever way you choose to work -- inductively or deductively -- the intellectual structure should be based on argument, be linked, and be as clear as possible.

不管选择哪一种方式－归纳或推演－聪明的结构应该以论点为基础或与其紧密连结，同时尽可能地清晰。

Major findings include:(1) Students tended to follow the writing convention of argumentative essays by simply dividing their compositions into three paragraphs, and the poor connection between the three parts made the compositions incoherent in overall organization;(2) Great number of inappropriately used cohesive devices seriously impeded the cohesion within paragraphs in students" writings;(3) Deficiently assembled thematic progression patterns were identified, which also proved that students" writings were incoherent in meaning.

主要分析结果包括：1。多数学生作文写作段落的形式上与议论文与作规范统一，但文章各部分内在衔接不好，导致作文从整体结构上不连贯。2。学生作文中出现的大量衔接手段错误使得作文令人费解。 3。学生使用了几种议论文中常用的主谓推进模式，但这些模式之间结合不紧密也证明了学生作文在意义上的不连贯。

In the methods of research, this paper pays attention to the combination of demology, economics and sociology etc, uses the scientific elements in the existing research results, and unites it with the reality of China closely. In the background of dualistic structure, it emphasizes particularly on the rural old-age security issues to do an intersectional research. It combines the theory with the reality, combines the qualitative research and quantitative research. The countermeasures are realistic, feasible and far-sighted.

在研究方法上，本论文注重人口学、经济学、社会学等理论方法的结合，合理借鉴国内外已有研究成果科学成份，紧密结合中国实际，在"二元结构"大背景下，侧重对农村养老保障问题进行交叉研究，做到理论与实际想结合，定性与定量分析相结合，对策研究注重现实性、可行性和前瞻性。

Gradually turned into two feet to walk upright, hand, foot and division of labor, will use stones, sticks and other natural tools; body structure compared with Dryopithecus progress, dental arch into the arch, the teeth arranged more closely, canines are not prominent, molar greater occlusal surface, the dolphin's back back, stands about 1 meter, the brain is about 300 milliliters; mainly eat plants, and carnivorous.
