  1. Two significant technologies were analyzed for stage lighting control system sine wave dimmer and network management in this paper

    對燈光控制系統中的兩項重要技術? ?正弦波調光和網路化管理進行分析和探討。
  2. This technology broke the tra - ditional microwave therapy machine sole sine wave output treatment function, the newly creation had the pulse wave and the sine wave two kind of profiles outputs treatment function, thus has established okw series microwave therapy machine in the domestic leading status, has filled the domestic blank

    自行研發生產的奧克微微波治療機，擁有自主知識產權，已獲國家頒發發明專利證書。該項技術打破了傳統微波治療機單一正弦波輸出的治療功能，新創具有脈沖波和正弦波兩種波形輸出的治療功能，從而奠定了
  3. The reseach work focused on the time delay estimation of the common practical radar singnals, including harmonics signal, chirp signal, polynomial phase signal, and phase - shift keying signal. the new algorithm for different radar signals are deduced in detail respectively, and simulation results are presented. the results proved that the new method is efficient for time delay and some other parameters estimation

    正弦信號、線性調頻信號、多項式相位信號、相位編碼信號是雷達信號中常用的幾種信號，對這幾種信號的研究是雷達信號處理中非常重要的內容，也是實際工程的需要。因此，本文選擇上述幾種信號作為研究對象，對這幾種信號的時延估計演算法進行了建模和理論推導，給出了時延估計演算法的具體表達式，並進行了計算機模擬。
  4.

  5. The thesis mainly deals with the third part of across : " sompi " cepstrum methods. the principle and system structure of across a re first introduced. the propagation of wave in media is simply studied and its transfer function in frequency domain is modeled as superimposed damped exponential sinusoids, each damped exponential sinusoid is called as a wave element and its exponential index part consists of two factors : group velocity travel time and decayed factor

    為此，首先介紹了across的原理與組成和通過簡單地討論地震波在介質中的傳播情況建立起介質的傳遞函數模型，指出：在一個狹窄的頻率窗口裡，介質的傳遞函數可以用有限個阻尼正弦項的疊加的形式表示，每個阻尼正弦項代表一個波成分，其指數部分包括兩個因子：波成分在介質中的傳播時間和衰減因子。
