網地に於ける張力の分布(II)

Abstract

In the present experiment, the authors studied Pearson's coefficient of variation, V, of the tensions on the arms of the nets of various materials by the similar method reported previously1). The observations were carried out first wih the nets stretched lightly and then with the same ones stretched heavily. The results of calculation, which are tabulated in Tab. 1, indicate (1) that in the same net, V is greater in the heavily stretched state than in the lightly stretched state, and (2) in the heavily stretched state, V of the net of trawl knots is greater than that of the net of flat knots.
