抄録

As a experiment of flowing model, I used a long sloped U-shaped gutter having variable width, in which tried to roll over many golf balls, pingpong balls, small steel balls, many times for each, and recorded the average numbers of flowing balls par second for each width. Against a simple conception that the flowing balls increase in number in proportion to the enlarged width of gutter, at some specific width being slightly insufficient to multiple length of diameter of the ball, the number of flowing ball, the number of flowing balls dropped down remarkably. And when the width slightly surpassed them, the number of flowing balls increased extremely. On any occasion in common, especially in narrow width, appeared distinctly these phenomena. When these phenomena in the movement of floating model are substituted for floating multitude, it can be said that, as a hypothesis, there are several advantageous width bands being able to circulate relatively larger number of people, and on the other hand likewise, several disadvantageous width bands.
