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。

The circulation of solids between two fluidized beds makes it possible to transport the vast quantities of heat produced or needed in large reactors.
固体颗粒在两个流化床层之间循环，使得大型反应器中产生的或需供给的大量热量有传递的可能。

A new hybrid method for prediction of solids holdup in gas-solid circulating fluidized bed is proposed based on chaos phase reconstruction and wavelet package as well as neural networks.
