    該系統能產生三相六路正弦脈寬調制（ spwm ）波形;調制頻率范圍為0 4khz ，分7級控制; 16位的速度控制解析度;載波頻率分8級控制，最高可達24khz ;系統介面兼容intel系列和motorola系列單片機;該系統控制簡單、精確，易修改，可現場編程;同時具有脈沖延時小、最小脈沖刪除、過壓和過流保護功能等特點，可應用於pwm變頻調速系統的全數字化控制。
  3. Then the pulse is modulated by pwm. after the modulated signal through a low pass filter, we can get the change of the frequency that related to the capacitor

    對頻率變化的脈沖進行寬度調制，通過低通濾波就可以輸出頻率變化量，也就可以得到相應的加速度值。
  4. It is found from the experiment that under the conditions of peak magnetic field of 0. 57t, beam pulse fwhm ( full width of half maximum ) of 44ns, a microwave radiation pulse with fwhm 25ns and whole width of 35ns is produced, when the intensity of the guiding magnetic field rises, the peak microwave power changes little but the width of the pulse reduces. the a - k gap also has obvious influence on the microwave radiation, the stable and higher microwave output is obtained under suitable gap

    實驗中還發現，在峰值磁場0 . 57t和束流半高寬44ns情況下，得到了25ns半高寬和35ns底寬的微波脈沖信號，隨著導引磁場增加，微波信號幅值基本不變，但國防科學技術大學研究生院學位論文是微波脈沖寬度會逐步減少;實驗中還發現磁場線圈位置有一定的軸向調節范圍，說明在磁場軸向分佈的一定變化范圍內，器件都可以正常工作，這對以後的永磁場系統導引的微波實驗有利。
  5. With variable edge time, pulse width and voltage level, the 33250a is ideally suited to a wide variety of pulse applications

    它具有可變的跳變沿時間，脈沖寬度和電平，是適應您各種
  6. When pulse width is long enough to above 2. 5ms, the corrected direction of laser hammering is away from the laser head, which may be the reason for weld bath being fatal destroyed

    當脈沖寬度超過2 . 5ms時，由於熔池發生了復雜的變化，有可能使激光錘校正方向相反從而難以預測。
  7. Porras and fu et al proposed that slowly varying envelope approximation and the complex amplitude envelope do n ' t fit anymore for the ultrashort pulsed beam shorter than or even near to one oscillation optical period, because they lead to a spatial singularity

    結果表明，對于脈沖寬度較長（相對於一個光學周期）的超短無啁啾脈沖光束可以使用緩變包絡近似和復振幅包絡表達式。
  8. Variable width pulse
