閃爍頻率
Nowadays, the photoelectric flame detector is widely used in the power plants. The principle is to analyze the intensity or flicker frequency of radiation.
目前國内外電廠使用的多為光電式火焰檢測器，其原理是分析火焰燃燒時輻射光的強度或閃爍頻率。
At present, our country power quality national standard was chiefly stipulated five quotas: frequency, harmonic and voltage deviation, three-phase unbalance and the voltage fluctuation and flicker.
目前我國電能質量國家标準主要規定了五個指标：頻率、諧波、電壓偏差、三相不平衡及電壓波動與閃變。
Second , the noise of double balanced mixer was analyzed, which involved analysis of low frequency flicker noise and high frequency thermal noise.
接着對雙平衡混頻器的噪聲進行理論分析，包括低頻閃爍噪聲和高頻熱噪聲。
This method not only can achieve the distortionless envelope detection of voltage flicker, but also can detect the time, frequency and amplitude of the signal accurately.
該方法不僅能夠對電壓閃變信號進行不失真地包絡檢波，而且能夠精确地檢測電壓閃變信號的時間和包絡信號的頻率分量及其幅度。
It covers five aspects: supply voltage tolerance, utility harmonic, three-phase voltage unbalance, power system frequency tolerance, voltage fluctuation and flicker.
它涵蓋五個方面：供電電壓允許偏差、公用電網諧波、三相電壓不平衡度、電力系統頻率允許偏差、電壓允許波動和閃變。
“Flicker frequency”是一個技術性術語，主要用于描述光源或顯示設備的閃爍特性。以下是詳細解釋：
Flicker（閃爍）
Frequency（頻率）
Flicker frequency 指光源或顯示設備中光線明暗交替的頻率，即每秒閃爍的次數。例如：
單詞："flicker"
用法：動詞
解釋：忽隱忽現，閃爍不定
例句：
The candle flame flickered in the wind. (蠟燭火焰在風中忽明忽暗地閃爍)
The television screen flickered for a few seconds before going black. (電視屏幕在黑屏前閃了幾秒鐘)
近義詞：twinkle, shimmer, flash, sparkle, glimmer
反義詞：steady, still
單詞："frequency"
用法：名詞
解釋：某一事件、現象或波動在一定時間内發生的次數
例句：
The frequency of earthquakes in this region is quite high. (這個地區的地震頻率相當高)
The radio station broadcasts at a frequency of 95.5 FM. (這個電台的廣播頻率是95.5 FM)
近義詞：rate, speed, tempo, cadence
反義詞：rarity, infrequency
