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。

In my opinion, the simplest approach is: Normally, the hard drive to back up a partition table (not, to find a model with the same hard disk partition table can be), the event was to get rid of a hard disk, floppy disk with both fixed, it can be hard in the bios will set none, to start after the backup to restore the partition table back to the hard disk and then change the settings back from the new start, fdisk it.

我认为，最简单的办法是：在平时，将硬盘的分区表备份一个（没有的话，找一个与之相同型号的硬盘的分区表也可以），万一硬盘被干掉了，用软盘都起不动的话，可以在bios里将硬盘设为none，启动后，将分区表的备份恢复回去，然后将硬盘的设置改回来，从新启动，fdisk就可以了。
