【Abstract】 It is successful to be shown up by the test that the generalmeasuring force balance of the wind tunnel was applied to the desert re-search.The design eliminated the influence of the bigger dead weight ofthe soil.The balance has the higher sensitivity,The complete balancesystem can be elevated or descended according to the soil channel.It is thebetter tool that has ever been used for the sand transportation study.更多还原
