為了發展液晶視流技術，首先改進塗抹方式，表面塗抹不確定度從大於50%降至低於20%，甚至低於10%；校驗的結果則發現，光源亮度不影響彩度擷取，其不確定度為2.16%，光源角度則影響顯著，不確定度為 13.85%；嘗試調配高分子聚合物混合液晶經過校驗後，發現其顯示效果不如沒有聚合物混合的液晶；在實際應用於分離流實驗中，比較液晶影像與油流結果，顯示了模型頂面的再回復位置，以及兩側渦流的流動現象，兩側渦流尺度佔風洞寬度的12/15，三維效應顯著。綜合言之，實驗結果說明此自行發展的技術可以用於探討三為非定常分離流。

　　In developing the liquid-crystal flow visualization technique, we first improved the way of coating. The variations of Hue level on a flat surface was decreased from more than 50% to less than 20%. Also, it is found that varying light source intensity does not affect the hue level acquisition appreciably, that the uncertainty of intensity is 2.16%, but varying light source angle causes the uncertainty 13.85%. On the other hand, the color images obtained from the composition of liquid crystal and polymer was inferior to that of liquid crystal without polymer. In applying this technique to an experiment with flow separation, comparision of liquid crystal image and oil flow visualization results reveals the position of reattachment and the three-dimensional structure of the flow reattachment. In summary, the results obtained confirm that the technique is promising for studying the unsteady, three-dimensional characteristics of separated flow.
