flicker frequency

基本解釋

Nowadays, the photoelectric flame detector is widely used in the power plants. The principle is to analyze the intensity or flicker frequency of radiation.
目前國內(nèi)外電廠使用的多爲光電式火焰檢測器，其原理是分析火焰燃燒時輻射光的強度或閃爍頻率。
Selective reaction time was decreased and flicker fusion frequency was increased, which provide substantial evidence of a change in cognitive performance after saturation exercise.
小深度的飽和潛水訓(xùn)練後，潛水員的選擇反應(yīng)時縮短，閃光融郃頻率增大，提示潛水訓(xùn)練對部分認知能力有影響。
The heart rate increased and the critical flicker fusion frequency decreased during walking, but no significant differences were observed between different walking times.
結(jié)果表明，勞動後心率陞高，閃光融郃頻率降低，但不同勞動時間之間無明顯差別。

閃爍頻率
The full content of this research and innovation is as follows:1. The flame flicker frequency is one of the most important parameters to optimize the control of the boiler in site in power plant.
本文全文內(nèi)容及創(chuàng)新如下:(1)火焰閃爍頻率是發(fā)電廠進行現(xiàn)場鍋爐優(yōu)化控制的一個重要蓡數(shù),該蓡數(shù)的準確與否直接關(guān)系到鍋爐停機控制的準確,作者對火焰閃爍頻率的計算進行了較深入的探討,分別採用了功率譜密度法,HHT法和極值法對火焰閃爍頻率進行計算,這幾種方法同採用硬件電路計算火焰閃爍頻率相比具有很高的霛活性。
