煤礦許用炸藥可燃氣安全度試驗中配置甲烷氣體是檢驗的關鍵，傳統的三種配置標準氣體的方法(重量法、分壓法、流量法)不適合在本系統使用。筆者結合現實的手工配氣
過程，設計一種快速、精確的二步法專家控制配氣方法，并用反復學習算法實現自動調整專家系統中的控制參數。使試驗氣體濃度精度符合GB18097-2000 國家標準，配氣過程由粗配和精調組成，所用時間比人工配制方法提高3～5 倍。

Abstract：Configuring CH4 is the key of the test In the degree of safety test of explosive
inflammable gas, the three traditional methods (by weight, by voltage divided, by flux) in
configuring standard gas is not suit for this system. The author designs a swift and exact
two-step-expert-method, which is combined with the manual configuring process, and achieves the auto-regulation of controls parameter of the expert system by iterative learning arithmetic. The concentration of testing gas fits for the GB18097-2000.The process consists of the cursory regulation and exact regulation and the time is one-third to one-fifth of the manual configuration.
