摘要
针对普遍使用的恒温式和静态式氧弹热量计，提出了同步检测内外筒温度的发热量测定方法．对内外筒温度曲线进行积分处理，推导出了冷却校正理论公式．利用试验边界条件和采用数值积分的梯形法则，进一步推导出了实用的高准确度冷却校正公式．以高准确度冷却校正公式为理论依据，采用同步检测内外筒温度方法。
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.
