| Abstract: | J-Integration of data-operation is introduced, and the mathematical model y=HoXk fitting Ioad-deflection curves is adopted. The R-curve is dealt with by one -variable linearregression methed, and the whole number calculation process by self-given BASIC programmethrough PB-700 microcomputer. |
