( 2 ) the liman problem is normally adopted to check the liability of numerical method. the calculation error was within 9 % by comparison with the theoretic solutions of liman problem in the following case, the dimensionless calculation length was 2 with high pressure zone 0. 8, and the dimensionless state parameters were p1 = 2, p2 = 1, p1 = p2 = 1, u1 = u2 = 0. experiment results in literature [ 8 ] were used to check the adaptability of the numerical model developed here for unconfined gas cloud explosions and the calculation error was within 13 %
（ 2 ）數值方法的可靠性通常用黎曼問題的解析解檢驗，本文以無量綱計算區長度為2 ，高壓區長度為0 . 8 ，狀態參數為p _ 1 = 2 ， p _ 2 = 1 ， _ 1 = _ 2 = 1 ， u _ 1 = u _ 2 = 0條件下的黎曼問題解析解對所編制的爆炸場計算程序進行了考核，結果表明該程序的計算誤差在9以內；為考核本文計算模型預測開敞空間氣雲爆炸的適用性，以文獻[ 8 ]的實驗數據進行了校核，計算誤差在13以內。
