  1. 3. passive and active time - domain demodulation schemes were demonstrated based on a fiber bragg grating used as a tunable filter controlled by a piezoelectric stack, which was driven by an electrical sine wave signal. the measured strain applied on the sensor axially could be judged by observing the interval of the output between notches within a driving period in time - domain

    利用匹配濾波技術，分別採用無源和有源方式，藉助受pzt驅動的解調光柵，將待測應變信息變為時序負脈沖間隔的變化，利用常規的示波器觀測同一掃描周期中兩負脈沖在時域中間隔的變化來確定待測應變的變化。
  2. There are five parts are as follows : in part one, the concept of switching function is introduced first to establish the nonlinear mathematical model of the induction motor variable frequency speed adjustment system which is fed by a sine pulse width modulated ( spwm ) inverter and takes the effect of the main magnetic circuit saturation into consideration, then the low frequency oscillation of the system is simulated according to the model. next, from the view point of energy conversion of the inverter - induction system, a criterion for the low frequency oscillation is proposed to determine whether the system is in low frequency oscillation which is judged by whether the interval of the negative current component of the inverter input current is more than 1 / fc ( fc is the carrier wave frequency of the inverter ) or not

    首先引入開關函數概念，建立了正弦脈寬調制（ spwm ）逆變器供電異步電動機，考慮主磁路飽和時的變頻調速系統整體數學模型，模擬系統的低頻振蕩；其次從逆變器-異步電動機系統能量轉換角度出發，提出通過檢測逆變器輸入電流中負電流的間隔時間是否大於1 / f _ c （ f _ c為逆變器載波頻率）來判定系統是否出現低頻振蕩；最後的實驗結果驗證了系統低頻振蕩建模和判據的實用性和正確性。
  3. Following the rapid increase of the data transmission rate of optical fiber communication, the time slot confined by the time interval of the two successive signals is greatly shortened. under this circumstance, the effect of the fabry - perot filter to a short pulse signal may affect the following short pulse signals

    隨著通信速率的提高，相鄰的信號間的間隔越來越小，法布里-珀羅濾波器對某個信號的作用有可能影響下一個信號，因此研究法布里-珀羅濾波器對超短光脈沖的影響有著非常重要的意義。
  4. The echolocating calls in the state of fly were compared with those in the state of hang in two kinds of bats, r. yunanensis and h. pratti, and the doppler compensation effect was described. the analyzing result indicated that the frequency in hang was higher that that in fly, the duration and interpulse duration in hang were longer than those in fly, and the fm bandwidth in hang was narrower than that in fly

    比較了雲南菊頭蝠和普氏蹄蝠飛行狀態和懸掛狀態下的回聲定位聲波，描述這2種蝙蝠的多普勒補償效應，懸掛狀態聲波頻率顯著高於飛行狀態，聲脈沖時間和間隔時間顯著長于飛行狀態， fm帶寬窄于飛行狀態。
  5. Frequency diversity technique is effective in suppressing age if the frequency interval is big enough to remove off the correlation between the pulses transmitted by radar, wide - band mmw radar can satisfy the requirement but conventional microwave radar can t

    頻率分集技術抑制目標角閃爍的有效性，取決于去除脈間相關性的性能，即要求雷達發射信號必須有較大的頻率間隔，寬帶毫米波雷達正好滿足了這一常規微波雷達不能滿足的要求。
