imaginary frequency 中文意思是什麼
imaginary frequency
解釋
虛頻率-
The real part of the complex impedance decreases with frequency ; the imaginary part of the complex impedance increases with frequency to the maximum, and then decreases with frequency ; and phase angle decreases with frequency increasing
結果發現輝長巖復阻抗的實部隨頻率的增加而減小，而虛部隨頻率增加先增大后減小；相角隨頻率增加而減小。 -
The electric power harmonic comprehensive control system with low cast and high security is applied in this article. it adopts that sourced compensation links with non - sourced compensation herewhich the former is realized by high frequency pwm control technology and the latter is carried out by crystal switch formed by non - flow and over - voltage. it can realize stepless modulation with imaginary power, mightiness compensation of harmonic and negative electricity, and circuitry consumption debasing are achieved
提出採用有源補償與無源補償相結合的電力諧波綜合治理技術及裝置，無源部分採用無涌流和過電壓的晶閘管控制電容器技術實現，有源部分採用高頻pwm控制技術實現，成本低、可靠性高、可實現無功功率的無級調節、強力補償諧波電流和負序電流，降低線路損耗。 -
Plenty of experiments show the real, imaginary, module and angle of wavelet transform can accurately choose the fault line and precisely identify the high frequency of transient signals
通過大量的實驗，表明利用小波變換后的實部、虛部、模值以及相角可以準確的給出故障線路並高精度的提取故障信號的暫態高頻分量。 -
The second is to assure a multiple - parameter matrix characteristic equation has no nonzero pure imaginary roots. the key of this part is to verify that the structured singular value of a one - unknown matrix function is not equal to one. this work can be accomplished by a frequency sweeping test method
前者的核心是判定某常矩陣的結構奇異值不等於1 ，這只需計算常矩陣的結構奇異值；後者的核心是判定某個以頻率為變元的矩陣的結構奇異值不等於1 ，這一問題由頻率掃描測試法解決。 -
The imaginary part decrease with the shell of particles increase at 2ghz - 10ghz. the apex move toward the low frequency at 10ghz - 18ghz
