槍（砲）在射擊過程中，彈丸受火藥氣體之衝擊而射出槍膛，此時槍膛內壁主要受力有二：(1)發射藥燃燒所產生之高溫高壓。(2)彈丸嵌入管內壁之力，包含向前軸向推力及受膛線旋轉之力。由於本篇旨在估測熱源之熱通量，故後者暫不予考慮，僅就發射藥氣體所產生之高溫傳遞至槍管內壁進行熱通量估算。
眾所周知，在過去的熱傳理論中，已發展出許多逆向熱傳理論，在技術及應用上也日趨成熟廣泛，本文係以卡爾曼平滑技術(Kalman Smoothing Technique)作為估測熱通量之方法，並先在銅片上（一堆直角座標系）進行驗証；另以國造六五K2型槍管為例，分別模擬已知熱通量及實際量取槍管外壁上之溫度後，同樣的，利用上述演算法估測出槍膛內壁之熱通量，並據以解算出槍管壁任意位置之溫度分佈與時間之關係；經實驗結果證明該估算法則對於估測物體內瞬間產生之熱通量，是可行的。

Inverse Heat Conduction Problem (IHCP) has gradually been used to solve some of the heat source problem which generally could not be solved by Direct Heat Conduction Problem (DHCP) in recent year.
The copper will be used as a conductor in our experiment, by using thermocouple as a heat sensor, we can obtain the the measured data and use Kalman Smoothing Technique to estimate the heat flux. The thermal heat flux meter is attached to the other side of the heater for measuring heat flux simultaneously, which will be compared with the result of estimated heat flux.
Using the technique above, we can also obtained the relationship of heat flux and time-wise (Q-t chart) of a gun tube combustion chamber while the primers was ignited once the temperature of a gun barrel surface was measured. As to the temperature and time-wise (T-t chart) of inside body of the gun barrel, it can also be calculated.
