A calculation method is proposed to replace the current method of actual observation for assessing the rate of heat exchange between calorimeter vessel and jacket of the calorimeter. The experimental period of calorific value determination can thus be shortened. The essence of the proposed method is to base the calculation of the rate of temperature fall in the calorimeter vessel, v, on Mott's formula, v=a{t_c-t_j)+b x (t_j-t_a)+c, by using the relevant temperature differences.

A calculation method is proposed to replace the current method of actual observation for assessing the rate of heat exchange between calorimeter vessel and jacket of the calorimeter. The experimental period of calorific value determination can thus be shortened. The essence of the proposed method is to base the calculation of the rate of temperature fall in the calorimeter vessel, v, on Mott's formula, v=a{t_c-t_j)+b x (t_j-t_a)+c, by using the relevant temperature differences. The possibility of and the errors arising from substituting Mott's formula by a simplified one, v=k(t-t_j)-A, are shown next. Under the conditions specified in the National Standard GB213-79 "Method of Determination of Calorific Value of Coals", i. e., the difference between jacket and ambient temperatures should not be larger than 1℃, the error imparted to the result of calorific value of the simplified formula is usually less than 6-8 cal/g, which can be neglected for routine work. Appropriate correction, if necessary, can be made by rather simple calculation.

本文提出了一种确定恒温式热量计的内外筒热交换速度的推算方法,用来代替传统的实测方法,从而缩短发热量测定的时间。这种方法的要点在于根据Mott公式v=a(t_c-t_j)+b(t_j-t_a)+c由有关的温差计算内筒降温速度v。文章进一步论证了以简化公式v=k(t-t_j)-A代替Mott公式时所引起的发热量计算值的误差。在现行的国家标准GB213-79“煤的发热量测定方法”所规定的条件下(外筒温度与室温之差在1℃以内),这种误差不超过6—8卡/克,可忽略不计,必要时可以通过简单计算加以校正。

The surface temperature of the concrete dam blocks attected by the cold wave is analysed in this paper. The calculated relationship for the inner-outer temperature difference and the inner-surface temperature difference is obtained, thus providing the temperature control for the prevention of the surface cracks of the concrete dam blocks analytic evidence. This analysis is particularly significant to the surface protection.
