High Precision Cooling Correction Formula and Its Application

Based on the synchronous detection of the temperature of the calorimeter vessel and its outer tank for the commonly used isothermal or static oxygen bomb calorimeter,a new technique for the determination of the calorific value of the fuel was put forward and inferred according to the definite integrant of the curves of the vessel and tank a theoretical cooling correction formula .By using the experimental boundary conditions and the trapezoid rule of the numerical integral method,an applied high precise cooling correction fomula was deduced.By adopting the formula,an intellect measuring and controlling intrument with two thermometers was developed.
