我们报告了一种能够同时对湍流火焰中的次要物质浓度进行两点时间序列测量的技术。该实验装置采用皮秒时间分辨激光诱导荧光，空间分辨率小于 250 微米，时间分辨率小于 100 微米，可在空间和时间上解析许多湍流中的微米尺度。给出了 Re= 10,000 时标准湍流非预混火焰的两点时间序列数据，包括对潜在影响的讨论。
We report a technique that is capable of making simultaneous two-point time-series measurements of minor-species concentrations in turbulent flames. The experimental setup, which incorporates picosecond time-resolved laser-induced fluorescence, has a spatial resolution of less than 250 microm and a temporal resolution of less than 100 micros, which spatially and temporally resolve microscales in many turbulent flows. Two-point time-series data are given for a standard turbulent nonpremixed flame at Re= 10,000, including a discussion of potential implications.
