4. RPM可以用来真实地反映颗粒在离心管内不同位置的离心力及其动态变化。5. “r”代表转，“p”表示每，“m”指的是分钟，这三个字母组合在一起形成了RPM这一单位。6. 转速（Rotational Speed）指的是做圆周运动的物体在单位时间内沿圆周绕圆心转过的圈数。7. RPM与离心机产生的相对离心力（RCF...
RPM是转速的国际单位；“r”转；“p”是“每”的意思；“m”是“分钟”；速（Rotational Speed）：做圆周运动的物体单位时间内沿圆周绕圆心转过的圈数，叫做转速。RPM单位换算 离心机转速rpm与g的换算方法，RCF = 1.119×10-5× rpm2× r rpm离心机每分钟转速（r/min），只要给出旋转半径r（cm...
