For naturally cooled monobloc barrel, its thermal condition in regular regime can be evaluated by measuring the outside temperature of two arbitrary rounds;(2) During a sustained firing process, unsteady heat conduction exists in a monobloc barrel, whereas unsteady and quasi steady heat conduction exist with actively cooled composite barrels, meaning that the thermal condition changes from uncontrolled to controlled;(3) Different combinations of the convective heat transfer coefficient h and thickness of gun barrel δ have much effects on cooling the bore temperature.

利用有限元软件分析了某大口径火炮身管的温度场分布，并对自然散热条件下的单筒身管和主动冷却条件下的复合身管温度场进行了比较，其结果为(1)身管温度场分布存在初始和正规工况阶段，后者的单筒身管热状态可以通过测定任意两发身管外表面温度来评估；(2)持续射击过程中，单筒身管始终处于非稳态导热过程，主动冷却身管则包括非稳态和准稳态两个过程，实现了身管热状态由不可控向可控转变；(3)对流传热系数h和身管壁厚δ的组合对降低内膛温度具有很大影响。

Whether the inner cylinder is drilled or not do not affect obviously the measurement accuracy. The accuracy of the drilled outside cylinder is higher than the undrilled ones, and the drilled holes are better to be equally distributed, further more, the number is less than 36 with the diameter of 3mm. The sealed outside cylinder can lower the measurement accuracy. The thinner material of sealed inside cylinder is and the more ventilative function is, the higher accuracy will be achieved. Moreover, when the space between inside and outside cylinder is smaller, the measurement accuracy also becomes higher.

结果表明：各处理精度均较高，最高达97.40%；内筒打孔与否对测量精度无显著影响；套筒打孔的处理比不打孔的处理精度更高，且孔洞适宜均匀分布，但数目不可过多，直径为3mm时不宜超过36个；套筒封底会降低测量精度，内筒封底材料越薄、透气性能越好精度越高；内筒与套筒的间隔较小时精度更高。
