  1. Abstract : we have studied theoretically a beat effect in a four - level system due to fifth - order optical polarization, and considered the cases that the pump beams have either narrowband or broadband linewidth. we have found that the accuracy for the energy - level splitting measurement is determined by the homogeneous linewidths of the optical transitions. that is to say, this technique can achieve doppler - free precision in the measurement of the energy level splitting between two excited states which are dipolar forbidden from the ground state

    文摘:研究了四能級系統中基於五階極化的拍頻效應，考慮了抽運光束為窄帶線寬或寬帶線寬的情形.發現其對能級分裂的測量精度決定於光學躍遷的均勻增寬.也就是說，這種技術在測量與基態是偶極禁戒躍遷的兩激發態之間的能級分裂時，可得到消除多普勒增寬的精度
  2. In this paper, a new control strategy based on the adaptive deadbeat voltage space vector is presented. this control scheme has a lower sample frequency and a smaller difference between switch frequency and sample frequency. it has many advantages, such as producing zero vectors organically, tracing exactly, non - shaking, etc. and its dynamic response is better

    對于電能質量調節器來講， pwm跟隨指令參考信號的控制性能在很大程度上影響著裝置的補償效果，本文選擇無差拍電壓空間矢量控制為系統控制策略，這種控制方法具有采樣頻率低，開關頻率與采樣頻率的差距小，能有機地產主零矢量、跟蹤精確以及無抖振等優點，動態響應快。
  3. Secondly, the squeezing properties of the light of the f - type quantum - beat three - level atom interacting with the single - mode radiation fields in squeezed vacuum states or in binomial states have been studied by means of quantum theory and the numerical method

    論文的第二部分研究了v -型量子拍頻三能級原子與單模壓縮真空場和二項式態光場相互作用過程中光場的壓縮效應。
  4. The multicenter superwide view reappearance system which based on a technique of digital video composition is a complete set of innovative technological system from photographing and producing to output in partition and then to network synchronous playing and till a integral display. it applys many kinds of modem technique, such as photographing, digital video producing, multimedia, network and display, and on the commonly used platform it has realized a effect through software technique that only expensive and special equipment can achieve

    基於數字視頻合成技術的多通道超寬視景再現系統，是一種從拍攝製作到分割輸出再到網路同步播放直至一體化顯示的一整套創新的技術體系，它整合應用攝錄像技術、數字視頻製作技術、多媒體技術、網路技術、顯示技術等多種現代技術，在通用設備平臺上，利用軟體技術實現了昂貴特種設備才能實現的效果。
