- 中文摘要: To enhance the efficiency of scalar field investigation, a multi-channel detection system which is able to detect the concentrations of 35 measuring points simultaneously is developed in the study. According to the experimental results, the noise characteristics shall affect the quality of the concentration data. The method employed in our study is obviously successful in controlling the noise level. The calibration precision of 35 channels ranges from 0.07 ppb to 0.16 ppb while the coefficients of determination are larger than 0.9999 for all of the channels. From the scalar measurements of pure jet flow, it is found that the results perfectly agree with those of previous studies while, due to the simultaneous measurement, the amount of data which deviates from the fitting curve is largely decreased. It is concluded that the system possesses superior ability in investigating the characteristics of scalar field.
