速度

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

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。

The objects of the study are those 6 athletes who had good and steady grades above 15.00m in the pre-contest evaluation during the 9th National Sport Meeting once held in Nantong in 2001.

The dissolution remarkedly slows down when the dissolved percentage of Ti is in excess of 22% due to lower reactivity of the perovskite and the coverage from silicic acid, of which the former may be the primary reason.

当钛的浸出率超过22%以后，浸出速度显著下降，这是钙钛矿的反应活性差以及硅酸的包裹所致，而钙钛矿的反应活性差可能是浸出速度显著下降的主要原因。

Heat transfer and velocity distribution in the flow of a cold,two-dimensional vertical liquid jet against an isothermal hot,horizontal plate were studied,by using similarity transformation and Crocco transformation.
