• 中文摘要： 本研究中探討大範圍氣水流量組合而成之雙相流譜。經分析以單一光察覺器測得信號之頻譜，而由單一參數HFCF建立鑑別雙相流譜之標準。依此標準，若考慮攪拌流則鑑別率為76％，若不考慮攪拌流則可達90%。本研究中之流譜鑑別標準可期望應用至其它可測量空泡分率的雙相流系統。
• 英文摘要： A wide range of combinations of gas and liquid flow rates to form various flow patterns are investi-gated in this study. By analyzing the spectra of signals detected from a single sensor by light techniques,the criteria of identifying two-phase flow patterns have been established by using only one parameter,HFCF. Reasonable identifying performance shows that 76% for churn is counted and 90% for churn isnot counted. The criteria applied to other void fraction measurable systems for identifying two-phaseflow patterns could be expected.
