本研究針對微小尺度的爆震管內，乙烯/氧氣預混焰從點火到生成爆震波的過程，利用火焰螢光和schlieren顯影，首先針對化學當量的乙烯/氧氣預混氣體在1 × 1 mm2的方形微槽中之反應波與震波動態進行實驗解析。藉由此研究可以進一步探討反應波在如此狹小的空間中與震波之間的交互作用，結果成功利用此實驗方法觀察到過程中出現的流場特徵，包含:前導震波、斜震波、先驅震波、震波叢集和爆震波轉變，也探討了流場特徵對反應波傳遞速度的影響。
第二部分，進一步改變乙烯/氧氣的當量比，利用不同的當量比條件來觀察反應波加速和流場特徵的變化，結果發現在1 × 1 mm2的方形微槽中當量比為0.5的條件下，反應波沒有出現爆震波轉變的過程，而在成功形成爆震波的當量比條件下，以當量比1.3能最快形成前導震波與最後的爆震波轉變，而形成爆震波的時間趨勢為一U型曲線。第三部分，透過乙烯/氧氣在化學當量的條件下，利用不同的管徑尺寸來觀察反應波加速和流場特徵的變化，結果發現在管徑尺寸為0.6 × 0.6 mm2 的條件下，反應波沒有出現爆震波轉變的過程，除此之外反應波的加速隨著管徑的縮小而加快。

To investigate the flame acceleration process in narrow channels with ethylene/oxygen mixtures the high speed visualization systems were used. The chemiluminescence visualization recorded whole process including from the ignition to final steady detonation propagation. The schlieren visualization was used to observe the interaction between shock waves and reaction wave. First we found five different features within the flame acceleration to detonation transition process in 1×1 mm2 channel with stoichiometric condition. Respectively, leading shock, oblique shock, precursor shock, shock cluster, detonation transition. Second part is changing the equivalence ratio to observe the influence from different fuel and oxidizer concentration. We found that there is no detonation transition occurred when in 1×1 mm2 channel and the fastest to become detonation propagation is at he trend of DDT time and equivalence ratio is like a U curve. Final part is changing the channel width to analysis the channel size influence on flame acceleration process and the flow features with stoichiometric condition. The DDT time is reduced in smaller channel and there is no detonation transition in 0.6×0.6 mm2 channel.
