frequency fluctuation

基本解釋

For uniform time sampling, the level of frequency fluctuation will greatly influence the results of spectrum analysis.
采用等時(shí)隙采樣方法，頻率隨機(jī)波動(dòng)的大小則會(huì)嚴(yán)重影響譜分析的結(jié)果。
The accuracy of the dielectric loss measurement based on harmonic analysis algorithm is greatly influenced by the frequency fluctuation.
用諧波分析法進(jìn)行介損測(cè)量時(shí)，很容易受到系統(tǒng)頻率波動(dòng)的影響，從而降低測(cè)量的準(zhǔn)確度。
The non-synchronization caused by the frequency fluctuation will cause remarkable error when the harmonic analysis method is used in the on-line monitoring of dielectric loss.
使用諧波分析法對(duì)介質(zhì)損耗因數(shù)進(jìn)行在線監(jiān)測(cè)時(shí)，由電網(wǎng)頻率波動(dòng)引起的非同步采樣會(huì)給系統(tǒng)測(cè)量帶來(lái)很大誤差。
