Any homogeneous viscoelastic medium subjected to one - dimensional tension and compression can be characterized in terms of the phase velocity c ( w ) and the attenuation coefficient deduce the complex modulus and the other equivalent viscoelastic functions
一維的縱向壓縮波在同質的粘彈性介質中傳播時，材料的粘彈性特性主要通過縱向波的傳播速度c （ w ）和衰減系數a （ w ）兩項來定義。 -
The voltage - controlled oscillator and the dual - modulus prescaler are the most crucial blocks in the pll frequency synthesizer. two kinds of voltage - controlled oscillator ( the quadrature voltage - controlled oscillator based on symmetrical spiral inductors and differential varactors, and the voltage - controlled oscillator with wide tuning range based on mos varactors ) and two kinds of prescaler ( the prescaler using phase - switching techniques, and the prescaler using dynamic circuit techniques ) are proposed. then, the complete pll frequency synthesizer is implemented, in which
壓控振蕩器和雙模預分頻器是鎖相環型頻率合成器中最關鍵的兩個模塊，本論文分別實現了兩種類型的壓控振蕩器（採用對稱螺旋型電感和差分二極體型容抗管的正交壓控振蕩器和使用mos型容抗管的大調諧范圍壓控振蕩器）和兩種類型的雙模預分頻器（使用相位開關技術的雙模預分頻器和使用動態電路技術的雙模預分頻器） 。 -
When a smoothing function ' s first derivative is adopted as wavelet function, the local maxima of wavelet transform modulus detect the location of signal ' s singularities, in this thesis, these characters are not only applied to measure the magnitude of dead angles of the dissymmetry inrush but also the symmetry inrush in three - phase transformer
當小波函數取光滑函數的一階導數時，信號小波變換的模在信號突變點將取得局部極大值。本文利用這些性質不僅對三相變壓器的非對稱性涌流間斷角的大小進行測量，同時還測量了對稱性涌流的間斷角，測量精度有一定的改善。 -
This method uses wavelet transform to pick up the transient fault information because of its multi - resolution characteristics and time - frequency localization nature. fault line is detected based on the modulus maxima or energy comparison under some scale of wavelet transform of phase currents or component current. this method is applicable for such power system as only furnished with ct on two phases, so the shortcoming of other methods presented in recent years is overcome
即利用相應出線相電流或分量的暫態信息突變量在小波變換某一尺度下模極大值或能量比較來確定故障線路，該方法同樣適用於只裝設兩相ct的小電流接地系統，從而克服了迄今為止提出的一些選線方法在系統只裝設兩相ct時失效的問題。
