A vibrating massager capable of being charged wirelessly comprises a vibrating massager body (1) and a charging base (2). The vibrating massager body (1) comprises a rechargeable battery (14) and charging coils (17) connected to two poles of the rechargeable battery (14); an induction coil (21) and a second circuit board (22) connected with the induction coil (21) are arranged on the charging base (2); and an input alternating current produces electromagnetic induction on the induction coil (21) after being processed by the second circuit board (22), so as to enable the charging coils (17) to produce voltages and charge the rechargeable battery (14). By adopting the charging manner, the battery of the vibrating massager does not need to be frequently replaced, so that the cost is low; a jack or a metal contact for inputting a power source does not need to be arranged on the vibrating massager, the integral shape of the outer surface of the vibrating massager does not need to be changed either, and the layout of components inside the vibrating massager does not need to be readjusted, so that the outer surface of the whole vibrating massager has an integral shape, the vibrating massager is integrally sealed and the safety performance is high; and the vibrating massager is totally waterproof, and water cannot enter the vibrating massager even if the vibrating massager is immersed in water.
A method for liquefying and saccharifying starch quickly, which includes steps of: irradiating starch with 0.25´106-1.5´106Gy 60Co-g rays or electron accelerator, putting the irradiated starch into a fermenting tank and adding cold water, stirring mechanically to form solution, adding a little amount of starch saccharifying enzyme to saccharifying the starch under acid condition.
