And the following conclusion was got : generally, the existence of particles would limit and retard the developing of the coherent structure of the turbulent fields ; but when the mass loading is a little high, the existence of particles would promote the developing of the turbulent field ; at the same time, the gas flow field would enhance the particles " dispersion. at this time, the interaction between the two phased would promote each other. this phenomenon is just like the " sympathetic vibration " in mechanical engineering
認為：在一般條件下顆粒的存在會限制、遲滯流場的發展；但對于質量2002年6月?金晗輝摘要攜帶率較高的情況，在流場發展到一定程度以後顆粒的反作用會促進流場的發展;反之，在顆粒質量攜帶率較高的情況下，受顆粒反作用的氣相流場又會加強顆粒在流場空間中的擴散，揭示出氣粒兩相相間作用在一定的顆粒質量攜帶率條件下存在「共振現象」 。 -
