摘要
本文从作为气温预测计算基础的井巷调热圈温度场入手研究，建立了优于一般差分格式的解算通风巷道调热圈半径及其内部温度场的不定区域异步长差分格式，并应用该模型得出了经过一定通风时间的巷道壁温可当作常量处理和调热圈半径与通风时间的平方根成线性关系这两个重要结论，从而为精确地进行气温预测打下了坚实基础。
On the basis of the conoept of control heat circle and its temperature field which are fundanmental to temperature prediction, a kind of difference equation based on undefinable area and unequal step is found, which is applied to calcultu the radius of control heat circle and its temperature fild and which is superior to the common difference equation. The important results are found by using this model, one is that the wall temperature can be consiered unchanged on condition that the ventilation is long enough,the other is that radius of control heat circle is in direct proponion to root of ventilation time, which is important to the prediction of air temperature. 4figs., 2tabs., 2refs.
