1、Dense phase voidage can be estimated by cutting gas flow and following the rate of bed collapse.
采用切斷流化床氣源，并跟蹤測量床面塌落速度的方法，可以測得濃相空隙率。

2、CALCULATION OF THE AVERAGE VOIDAGE FOR FAST FLUIDIZED BED
快速流化床平均空隙率的計(jì)算

3、To the solution mining in-sit, the voidage of dissolved glauberite is a crucial factor.
水溶過程中礦石的空隙度是確定該礦床能否采用原地水溶開采方法開采的決定性因素。
