The structure and function principle of a multiphase detonation tube are described. It is found that the tube can be used not only for gas-liquid two-phase detonation test but also for gas-liquid-solid three-phase detonation test. Compared the data listed in table 1,2 and 3,it is verified that the correspondent experimental results of epoxypropane (PO) and PO+Al in the said tube are close to those obtained from the field stationary blast test. Therefore the parameters from the tube test can give a valuable guidance to the related field test,which reduces the cost in experiment number and period.
