摘　　要：物理化学中两类作图法可求算物理量。一类是根据直线斜率求物理量,例如求标准摩尔反应热、摩尔蒸发热及摩尔升华热、反应级数、反应速率常数、活化能、弱电解质的电离常数和吸附平衡时被吸附气体的体积等;另一类是根据曲线上某点的切线斜率求物理量,例如求瞬时反应速率和表面吸附量等。The values of physical quantities could be calculated by two graphic methods was physical chemistry. One method is that the values of some physical quantities could be calculated by the slope of straight line such as standard molar heat of the reaction, molar heat of vaporization and molar heat of sublimation, reaction order, reaction rate constant, activation energy, ionization constant of weak electrolyte and the volume of the gas adsorbed in adsorption equilibrium and so on. The other method was that the values of some physical quantities could be calculated by the tangent slope of some points on the curve such as instantaneous reaction rate and surface adsorption capacity and so on.
