  1. The laser power is detected through the pd ’ s movement across the faculous region. when the value of the peak value of laser power is got, the power of the facular boundary points can be found according to definition of the facular boundary such as “ 1 / e ~ 2 ” theory. then the equation of the facular boundary can be made fitting by using the least square method, and calculate the beam divergence at last

    採用兩個光電探測器分別檢測光束不同高度上的兩個光斑，在確定光斑中心最大光強值后，根據光斑截面尺寸的1 / e2定義，得到光斑截面邊界點的光強值，並以其為標準判定光斑截面的邊界點，對探測到的邊界點通過最小二乘法進行擬合，得到橢圓光斑截面的方程，根據空間幾何關系求出發散角。
  2. The relation of tthe ccd sensor imaging resolution and the mtf is gotten. when the mtf of space remote sensing camera is higher and the contrast of object is higher, it can be believed that the resolution of ccd sensor imaging is 1. 6 times of the pixel dimension, in the mean while the mtf decreases 32 %

    通過模擬得到了ccd探測器的目標影像的分辨力與ccd像元尺寸的關系，當航天光學遙感相機的mtf較高（模擬中鏡頭的mtf = 1 ）且目標為高對比度時，得到ccd探測器的目標影像分辨力是其像元尺寸a的1 . 6倍，其光學調制度傳遞函數mtf下降32的結果。
  3. All of above make the miss distance of the missile difficult to estimate in shooting range. in order to solve these problems, a novel method for detecting and tracking small moving point target in image sequence is proposed in this paper, based on combination of the correlation of multi - frames and wave gate techniques. especially, the qualifications to confirm the target and the establishment of the wave gate based on size and characteristic moving parameters of the target are stressed in the paper

    針對目前靶場所面臨的測量目標小、距離遠、目標與背景對比度小，不具有形狀信息的實際問題，提出了一種基於多幀相關技術與波門選通技術相結合的快速目標識別與跟蹤方法，特別探討了多幀相關技術中目標確定的理論判據，並綜合考慮目標的尺寸因素和目標的運動特徵研究了一種新的波門設定方案。
  4. The results show that in the later stage of the nucleation process, the maximum slip velocity is monotonically accelerating ; the slipping hot spot ( where the slip rate is maximum ) migrates spontaneously from a certain instant, and such migration is spatially continuous ; when the maximum velocity reaches a detectable order of magnitude ( at least one order of magnitude greater than the loading rate ), the remaining time is 20 hours or more, and the temporal variation of slip velocity beyond this point may be used as a precursory indicator ; the average slip velocity is related to the remaining time by a log - log linear relation, which means that a similar relation between rate of microseismicity and remaining time may also exist ; when normal stress variation is taken into account, time scale of such processes can be extended by about 2 times

    結果表明，在成核的後期階段：最大位移速率單調加速增加；滑動熱點（最大滑動速率處）在後期階段開始自發性遷移，且在空間上連續；當最大滑動速率達到可以明顯探測的量級時（高於載入速率一個數量級以上） ，倒計時間為20小時或更長一些，這時的速率變化可作為臨震預測標志；平均滑動速率與倒計時間的關系在臨震階段呈對數線性趨勢，由此可推測微震活動增長率與倒計時間同樣存在對數線性關系；正應力的變化對上述時間尺度有延長作用，使之大致增加到原數值的2倍。
  5. It is appropriate commonly that the resolution of ccd sensor imaging is 1. 8 times of the pixel dimension, in the mean while the mtf decreases 11 %, because the mtf is bigger, the other parts are easier to be made and the image shows the characterization of the object well. 2

    一般情況下取ccd探測器的目標影像分辨力是其像元尺寸的1 . 8倍較為適中，因為這時的mtf數值較大對系統的其它環節的指標壓力較小，且圖像較好地反映了目標圖形的特徵，此時其光學調制度傳遞函數mtf下降了11 。
