By a general n th-order polynominal equation being transformed to a system of orthgonal functions, it was shown that optimal order in the equation which was filt to experimental data could be selected easily (see equation (10), (11)). Comparison of experimental values with calculated values in approximate curves is described in Fig. 3 to Fig. 5.}, pages = {129--135}, title = {土の応力,ひずみ~時間曲線の多項式近似について}, volume = {62}, year = {1981} }
