摘      要：The unit current powers have some disorder in different water drainage,they undulate between 0.02 - 0.14m/s,0.05 - 0.35m/s,0.15 - 0.55m/s in different grades slope;on 20°￡lope,the unit current power waved steady with time in 1,2 and 3L/min water drainage amount,the unit current powers decreased gradually first,and then got the waved steady in 4L/min water drainage amount,about 0.1 m/s;the unit current power was increasing -decreasing-waved steady in 5,7.5 and lOL/min water drainage amount;The unit current powers are increasing with slope grade increase except individual *** the initial stage,the unit current powers of 20°and 30°slope were closed,they increased firstly and then decreased,were bigger than 10°slope which was waved steady,the unit current powers of 20°and 30°slope got waved steady at 18min at 5L/min water drainage amount;they got the waved steady at 1 Omin,were 4 rimes of unit current powers on 10°slope at 7.5L/min water drainage amount.
