    系統採用電臺的電視伴音調頻信號，其中電臺信號與伴音信號功率之比基本為10 ： 1 ，並且目標散射信號較弱，一般情況下淹沒在雜波和機器熱噪聲之下，採用常規的脈沖檢測方法很難對遠距離的目標進行檢測，而以電臺直達信號作為參考與目標回波信號進行相關檢測；系統中信號的相關處理會產生旁瓣，而強目標的旁瓣會影響附近的弱目標檢測。
  4. The position and size of the monochromator, focusing curvature radii and tilting angles of the germanium focusing monochromator under different different take - off angle, size and divergency of the second collimator and intensity loss due to the use of it were determined. the neutron flux at different wavelength, under different reflection and take - off angle of the monochromator and divergency of the first collimator, were given. the simulation on the aperture used for limiting beam size in front of the sample showed that, smaller the size of the aperture and further the distance from the aperture to the sample, greater the loss of the intensity and more serious the spread of the beam along vertical direction at the sample position which makes the practical sampling volume greater than expected

    用蒙特卡羅模擬方法對中子應力衍射譜儀的設計方案進行了優化研究，提出了一系列可供參考的數據：確定了單色器的位置、尺寸、垂直聚焦單色器在不同起飛角下的聚焦曲率半徑和傾角；討論了第二準直器的尺寸和發散，以及使用第二準直器造成的強度損失；給出了在不同單色器反射面、起飛角、中子波長和第一準直器發散度的情況下樣品處的中子注量率，以及多種組合情況下譜儀的解析度曲線；對限束方孔的尺寸、距離樣品遠近對強度損失和測量中的影響做了深入研究。
  5. Such conclusion is given : shorten the fresnel shu, shorten the obscuration ’ s area percent and shorten the equivalent diffraction distances will improve the optical quality. ( 4 ) the nonlinear paraxial equation is understood to analyze the n slabs ’ hot - image rule

    得出在高功率固體激光裝置中應縮小散射點的菲涅耳數和散射面積比，控制散射點的等效衍射距離，使散射點接近等效衍射距離為零，即像面的位置。
  6. The appearance position of hot - image satisfied the rule of z2 = z1 - lv, z2 is mean the image distance, z1 is mean the object distance, and lv is mean the distance between the nonlinear medium. the theory is also validated by the optical propagation software. if n = 1, then the nonlinear medium is only one, lv = 0, and it will satisfy the rule z2 = z1

    四、從非線性近軸波動方程基礎上用散射矩陣理論推導了級聯介質的熱像規律，得出級聯介質的熱像位置滿足z2 = z1 - lv ，其中z2為像距， z1為物距， lv為級聯介質間的距離，並用光傳輸軟體得到了驗證;發現級聯的非線性介質可以看成單一的非線性介質相連，散射點對級聯介質的每一段非線性介質成像;當只有一段非線性介質時，可以認為lv為零，滿足z2 = z1 。
