在使用恒温法氧弹热量计测煤的发热量中,冷却校正值C的计算较麻烦。通常要分三步进行:一、计算a;二、计算V_n,V_o;三、以公式C=(n-a)V_n+aV_o计算C_o在实际工作中,可将第二、三步综合整理,简化计算,减少运算次数,较分步计算快速,方便和可靠。一、C计算式分别将V_n=K(t_n-t_j)+A,V_o=K(t_o-t_i)+A代入C=(n-a)
In measuring the calorific value of coal using a constant-temperature bomb calorimeter, the calculation of the cooling correction value C is troublesome. Usually in three steps: First, calculate a; Second, calculate V_n, V_o Third, the formula C = (na) V_n + aV_o Calculate C_o In the actual work, the second and third steps can be integrated to simplify the calculation , Reduce the number of calculations, compared to step-by-step calculation fast, convenient and reliable. First, the C calculation formula respectively substitutes V_n = K (t_n-t_j) + A, V_o = K (t_o-t_i) + A into C = (n-a)
