The relations between the deformation of the plate and the holder of the plate under the various pressures were investigated minutely using the apparatus which was newly devised by the writer. As the results of the experiments, it is showed that the thickness of the plate 0.50, 0.75, 1.00 % is respectively suitable to measure the depth of the nets or tools, when they are used in the depth of less than about 60, 80, 100 m.}, pages = {42--46}, title = {鉛板測深器の試作実験}, volume = {4}, year = {} }
