火焰电子温度测量方法的改进

Improved Method for Measurements of Electron Temperature in Flames

本文探索了采取校正的方法用改进的朗谬尔探针测量火焰的温度。该实验以液化石油气－空气在本生灯上的锥形火焰为对象，将探针置于火焰中施加电压，由电流反映温度的大小。该实验所采取的改进的探针法，解决了穿过火焰的探针法存在的一系列问题，使得测温在准确性、实用性及广泛性方面大大提高了一步。

calibration method using improved Langmuir probe to measure the temperature of flames is investigated. The experiment used a conic gas-air flame generated in a burner and a biased probe immersed in the flame. The probe current can reflect the flame temperature. This improved probe method solved a series of problems that existed in the cross-flame probe method and made the temperature measurement much improved in its accuracy, practicality and extensiveness.
