前进入料压力，可以增大矿浆流速，物料所受离心力增大，可以前进分级功率和底流浓度，但经过增大压力来下降分级粒度收效甚微，动能消耗却大幅度增加，旋流器全体特别是底流嘴磨损愈加严峻。
对于空调箱中的一般通风用过滤器，气流穿过滤材的速度在～/s范围内，阻力与风量不再是线性关系，而是一条上扬的弧线，风量增加30%，阻力可能会增加，若过滤器阻力对你来说是个非常重要的参数，你就要向过滤器供应商索要阻力曲线。

它集铝盐和铁盐各自优点，对铝离子和铁离子的形态都有明显改善，聚合程度大为提高。
因为滑动端在荷载作用下会有一定的滑移量，所以滑动支座在设计时有个重要问题就是要设限复位装置，并提供预计滑移量，防止连廊的滑落或与塔楼发生碰撞而造成结构的破坏。
图片来自新浪科技劳工组织、政府和经济学家担心，人类工人很可能会以前所未有的规模和速度被机器替代，从而加剧不平等并加重贫困。
