  1. Proved with the mixing rate using parameters tw and r ^ it showed that large amplitude and high frequency could greatly enhance the mixing rate. but at large st, the rate of attenuation appears to be in periodic fluctuation at the range of low frequency, so there must be some best partnership of amplitude and frequency

    用參數t _ w 、 r _ （ 15 ）表徵的混合效率表明：總的來說大振幅、高頻率有利於混合，但在st較大的低頻率區中衰減速度會有周期波動的特性，存在最佳的頻率振幅配對。
  2. It point out the resolving methods of the high frequency communication characteristic and its attenuation of the distribution network are the new research field

    指出電網的高頻通信特性及其抗干擾、抗衰耗對策是獨立於高性能載波晶元的研究領域。
  3. Against the background of the continuing spread of digital tv broadcasting, tachii electric wire has developed the tcx - hfbl series and tcx - fws series of high - frequency coaxial cable products. both of these series are compatible with the us smpte standard 292mhdtv and the japanese arib standard btas - 004b and are products that exhibit excellent attenuation characteristics by controlling return losses at a low level

    普及數字高清晰度電視播放的同時開發了適合美國的smpte規格292mhdtv ，日本的arib規格btas - 004b的高頻同軸電纜： tcx - hfbl系列， tcx - fws系列，有效抑制損耗，改善衰減特性的產品。
  4. High attenuation to low frequency, excellent perform ance of common mode and differential mode interfere nce suppression

    極佳的低頻段衰減特性，具有良好的共模和差模干擾抑制性能。
  5. The key points of this paper can be concluding as follows : 1. the regulations of vibration attenuation of a subway are concluded by analyzing the situ data. in the zone near rail, the high - frequency vibration is stronger than other weight, and in the zone far away from railway, the results is opposite

    主要研究內容和結果如下: 1 .對某地鐵線路環境振動實測數據進行了分析，得到了振動波在土中的傳播規律:地鐵運營誘發振動傳播過程中，近軌區域以高頻振動為主，遠軌區域以低頻振動為主。
  6. Rolling bearing ’ s vibration signal has a strong background yawp, the different fault cause the different characteristic of vibration. particularly the scathing fault, will not only cause the low frequency impact vibration, but also rise the high frequency inherence attenuation vibration of the bearing

    滾動軸承振動信號具有背景噪聲強、不同故障引起不同特徵振動的特點。尤其是損傷類故障，不但會引起低頻沖擊振動，還會激起軸承系統的高頻固有衰減振動。
