  8. Gas - solid two - phase flow is existed widely in multiphase flow system, for example, desert sand in nature, fuel transportation in field of chemical industry, metallurgy, energy sources and foodstuff, and so on, as well as pneumatic conveying and dust treatment of materiel in bulk ( i. e. sands, corn and plastic granula etc. ). in addition, sulfureted bed, whirlwind dust - exhaustion, sedimentation room and filtration process are involved with gas - solid two - phase flow

    氣固兩相流在多相流體系中普遍存在，例如，自然界的大漠揚沙，化工、冶金、能源和糧食等領域的燃料配送，散裝物料（如沙子、穀物、塑料粒）的氣力輸送和粉塵處理等，硫化床、旋風除塵、沉降室及過濾過程中也會涉及到氣固兩相流。
  9. Filtration is one of important operation units in water treatment operation process, and the sand granule used in the deep bed filtration is the key to perform a satisfied capacity

  10. In designing the deep bed, the empirical formula l / de = 800 is used as the basis. however, it has been proved that the formula cannot precisely describe the functional relationship and the correlation degree between the nitration behavior of the deep bed filtration process, the depth of the deep bed and the diameter of the sand granule, and it is restricted greatly in the practical application of finding a suitable depth of the deep bed

    目前，濾池的設計通常採用經驗公式i d _ e = 800作為設計濾池厚度的依據，但實踐證明此經驗公式還不能準確地反應濾池過濾特性與濾池深度l 、濾料粒徑d的相關關系及相關程度，在實際應用中受到很大限制。
