向心力“供不应求”或者“供过于求”都会引起脱轨,本文拟从不同角度谈谈离心现象和向心现象。一、离心运动做圆周运动的物体,如果实际提供的向心力小于所需向心力(即供不应求),将做离心运动而脱轨。离心沉淀(在同等条件下,密度大的物质最先离心)图1是医院常用的离心机原理图, “In short supply” to centripetal force or “oversupply” all will cause derailment. This paper intends to talk about the phenomenon of centrifugal phenomenon and centripetalism from different angles. Centrifugal exercise to do circular motion of the object, if the actual provision of the centripetal force is less than the required centripetal force (ie, in short supply), will do eccentric exercise and derailment. Centrifugal sedimentation (under the same conditions, the first centrifuge material of high density) Figure 1 is a schematic diagram of the centrifuge commonly used in hospitals,
