The key components in laser gyro is he - ne ring laser, and the reciprocal action theory between light and medium is the base in studying the ring laser, use the lamb half classical theory, and on the base of density matrix theory, the optical brounch equation was established, which described the movement of amplifying medium atom in the ring syntonic cavity, and according to the medium polarize theory the self consistent equations was deduced, which describe the light intensity and phasic of the counter - propagating wave. on the basis of this equations, adopted the simulation software matlab and virtual instrument programming language labwindows / cvi, we can do some simulated experiments in study the phenomenas such as amplify and dispersive characteristic of medium, mode pushing effection, burned hole effection and pattern competition, lock - in of frequency and the characteristic of light intensity and phasic of the counter - propagating wave in laser gyro
激光陀螺的核心部件為he - ne環形激光器，而掌握光與介質的相互作用理論是研究激光器的關鍵，採用拉姆半經典理論為主，在密度矩陣理論的基礎上，推導環形諧振腔中描述he - ne氣體增益介質原子運動的光學布洛赫方程，運用介質極化理論得出描述激光陀螺反向行波的光強、位相所滿足的自洽場方程組，在此基礎上，運用matlab模擬軟體和虛擬儀器編程語言labwindows / cvi ，對激光陀螺中的介質增益色散特性、頻率牽引效應、燒孔效應及模競爭、閉鎖效應及環激光的光強和相位特性進行模擬試驗研究，並且運用全量子理論，對激光工作原理進行分析，得出二能級系統單模輻射場的光子數密度分佈，得出激光場的光子統計分佈，模擬激光場的動態建立過程。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。On the basis of research available and through seven aspects : the family structure, vocational structure, the structure of the mode of life, psychological and cultural structure, income structure, organization structure and social identity, the thesis reflects the process of urbanization in the community between rural and urban areas, especially demonstrates the unique characteristics of urbanization in the community between rural and urban areas of the east of china by taking shui village and kong village in anning district lanzhou city of gansu province as the example and using the advantage of multiple subjects such as sociology, anthropology, economics, etc. the transition of the community between rural and urban areas is their imitation and incorporation into the urbanization, and the effect of their spread and radioaction
本研究在已有研究的基礎上，應用社會學、人類學、經濟學等學科的綜合研究的優勢，以蘭州安寧區水村和孔村為例，通過對兩村家庭結構、職業結構、生活方式結構、心理文化結構、收入結構、組織結構和身份認同等七個方面的實證研究，反映了城鄉結合部的城市化進程，特別是反映了中國西部內地城市化進程獨特的特點。城鄉結合部轉型過程是城鄉結合部自身模仿、融入城市以及城市的擴散輻射效應嵌入的過程；城鄉結合部是許多矛盾、困惑及經驗反映最集中的場所；同時是將漫長的城市化進程濃縮在一個短期內進行的相對較小的區域。Then we consider the problem as a " conjunction " problem : according to the solutions for wave problem in interface between two conjunctive homogeneous elastic half - spaces as well as the scattering problem of sh - waves by an arbitrary - shape - cavity in homogeneous material, we divide the elastic space with an interface cavity into two parts along the interface, each is elastic half space with an arbitrary - shape - canyon. and then dividing surfaces are loaded with undete rmined antiplane forces, and with some antiplane reacting forces to appear cracks
然後將界面任意形孔洞和孔邊裂紋對sh波的散射問題視為「契合」問題：即從兩個相互契合的完整彈性半空間的界面波動問題和彈性均勻介質中任意形孔洞對sh波散射的解答出發，沿界面處將含孔洞的彈性空間剖分為兩個含有任意形凹陷的彈性半空間，在其剖分表面上加置未知的反平面荷載，在出現裂紋的位置加置反平面反力構造出裂紋。The quantitative expression for speckle correlation function is formulated, in which the scattered intensity profile reciprocated on the surface plane acts as the aperture function in van cittert - zernike theorem
我們首先得出了散斑相關函數的定量表達式，該式表明散斑相關函數實際上是在vancittert - zernike定理中等效地將散射輪廓函數反演到散射體平面內作為散射孔徑函數的結果。分享友人
