最快速度

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 ,it maybe flow if screw back pressure too high .

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，半夜盗汗897就去播播Z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。

In this algorithm, inertia weight is nonlinearly adjusted by using population diversity information. Velocity mutation factor and position interchange factor are both introduced and the global performance is clearly improved. The algorithm has been applied to optimization of parameters in SVM.

The effectiveness of this method depends basically on two values,Гmin the search is faster for larger Гmin and the size of Pref (RE (the search is faster for less prefixes), where Гmin donate the shortest path from the initial state to a final state of the Nondeterministic Finite Automaton and Pref the prefixes of length Гmin for all the strings matching the regular expression. The size of Pref can be exponential in m and for multiple expressions matching the Pref will be much larger.

现有的正则表达式搜索算法性能较好的是多模式过滤类型的算法，此类算法严重依赖于两个因素，从NFA的初始状态到终止状态的最短路径Lmin和正则表达式所表达的语言的前缀集合Pref的大小，Lmin越长，搜索速度越快，Pref越大，搜索速度越慢。

The genetic algorithm pays attention to unknown area search . It has high speed and relative low precision. It will not get into local extremum. The BP algorithm searches the area that include whole-space minimum. It can improve speed and recision.

遗传BP算法利用遗传算法进行全局搜索，注重搜索未知区域，处理速度快而对精度要求不高，不易陷入局部极小点，而利用BP算法搜索有最优点的区域，提高搜索速度和精度。

Perhaps even more importantly, they also found that the flow was faster at sunspot cycle minimum than at maximum and substantially faster on the approach to the current minimum than it was at the last solar minimum.

也许更重要的是，他们还发现，流量速度远远快于在最大太阳黑子周期的最低，大大快于目前最低的方法比在最后太阳最低的。

Firstly, on the basis of summarizing the research results, this paper deeply discusses the calculating model to analyze the instantaneous motion state in vehicle collision and the interrelation between restitution coefficient and vehicle collision speed.

This new time brings not only unprecedented more chances, but also challenges and conjunctures. Globalization increase the difficulty of monopolization, for information spreads more quickly and it is easier to imitate. A leader should have outstanding mental personality and be capable to solve problems immediately. He can be composure in violent competitions and be aware of what he wants, not being disturbed by the environment. He can bring his team confidence and give the opponents pressure.

这个时代在带来前所未有的机遇的同时也充满了挑战与危机，全球化增大了垄断的难度，任何对手都拥有历史上最便利的机会掌握最新的信息，传播速度更快，模仿更加容易，领袖们必须具有良好的心理素质与处理危机的能力，能在快节奏的竞争中保持冷静与清醒，执著于目标而不易为外因所扰，带给成员信心，也带给对手压力。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
