绞丝旁加乞念什么>黄鹤楼送孟浩然之广陵的意思摘要：A rotation driving system drives unitedly and rotatably sprinkle rotors, which the disk sprinkle rotors having plural partitive members extending in predetermined distances in a radial direction to the rotating axis are arranged in multistage state with a predetermined distance in a longitudinal direction. In the aforementioned state, by supplying the catalyst to the center of the sprinkle rotor, the catalyst is fed into a reaction tank while releasing in a radial direction of the sprinkle rotor. When the catalyst is fed, a rotation frequency of the sprinkle rotor is defined to be a speed constituent in a radial direction of over zero when the catalyst ttles down and to be periodically changed between a maximum rotation frequency and a minimum rotation frequency. And further, a diameter of each sprinkle rotor being defined as measure to cau a position where the catalyst, relead from the lower sprinkle rotor rotating in the maximum rotation frequency Nmax, ttles down and a position where the catalyst, relead from the upper sprinkle rotor rotating in the minimum rotation frequency Nmin, ttles down to be nearly equal to one another. Therefore, the catalyst is fed in a uniformly scattering state by rolling in the radial direction after ttling down and the position where the catalyst ttles down in the radial direction is periodically changed, whereby the catalyst
can be uniformly fed in the radial direction.
