The revertex mechanical bit general many are the heterogeneous bit, mainly has each kind of tooth profile even Yuan Dao and the strip forming tool. 塑胶机械刀片一般多为异型刀片,主要有各种齿形平元刀及条型刀。
Suitable for wire installation into network and telecommunication head of tools which is made of special material makes tools more bit and spring made of excellent metal strip and spring steel. 传动部分的材料采用优质的工具钢、刀头和弹簧钢加工制成。
In order to consider the use of truck, forklift, discharging place, shovel bit and so on, some multiobjective programming models for produce of strip mine and a plan of vehicle is obtained, and genetic algorithm and maximal entropy algorithm are given. 建立露天矿生产及车辆安排问题的多目标规划模型,综合考虑卡车、铲车、卸点、铲位等生产设备的利用,并给出了其相应的遗传算法和最大熵算法。
Confirmed by experiments, geometric hair and R& D of self-containment bit anti-cross-roll system also applies to other large-scale high-speed precision strip mill. 通过实验得到证实,几何牵制法和研发的自位防交叉辊系同样适用于其它大型高速精密板带轧机。
