摘要

PROBLEM TO BE SOLVED: To determine a snow particle size without requiring labors and time, even when sieving is applied to determine the snow particle size while holding objectivity for measurement, when determining the snow particle size. SOLUTION: This sieve 5 for determining the snow particle size comprises a plurality of nets 3a-3e arrayed plane-likely and different in meshes, and a frame for partitioning the respective nets.
