DISTRIBUTION STATE OF SUPERCOOLING WATER AND ICE CORE.RATIO MEASURING METHOD UTILIZING DIFFERENCE BETWEEN LIGHT REFLECTION FACTORS, SOUND REFLECTION FACTORS, AND RADIO WAVE REFLECTION FACTORS OF SUPERCOOLING WATER, ICE CORE OF JET FLOW, IN SNOW FALL OF ARTIFICIAL SNOWFALL MACHINE AND OPERATION OF ARTIFICIAL SNOWFALL MACHINE UTILIZING IT

摘要

PROBLEM TO BE SOLVED: To provide a method to measure the distribution states and the distribution ratios of supercooling water and an ice core by irradiating light, or an acoustic wave, or a electric wave by irradiating light, the acoustic wave, and the electric wave with a snowfall injection flow of the artificial snowfall machine and by utilizing a difference in a reflection ratio between supercooling water and the ice core, and a method to effect feedback control of operation of the artificial snowfall machine. SOLUTION: Jet fluid (2) of the artificial snowfall machine (1) is irradiated with light from a light irradiation device (5). Its reflection light is received by a reflection light receiving device (6) and transmit it to a picture processing device (7) through a signal live (8) and snowfall is controlled by the transmitted signal.
