The inventory of solids in a fluidized bed can easily be found by pressure drop measurements across the bed. 流化床内的固定藏量可以用测定床层的压降办法很容易地求得。
Because of this rapid attainment of equilibrium it is not practical to measure the temperature difference between gas and solid at the bed exit. 由于达到平衡很快，故测定床层出口处的气体和固体温度差是不实际的。
