  1. According to the guidline, two nd : yag lasers have been designed and set up, one is end - pumped by lower output power ld using a selfoc micro lens, and the other is end - pumped by high output power ld using a pair of lenses are designed, and the characteristics such as output power and power stabilization of both solid - state lasers are investigated. thirdly, when an empty liquid crystal cell is inserted in the cavity of the nd : yag laser pumped by high power ld, the laser can operates in single axial mode. finally, according to the relationship between the laser output power and the longnitudinal a ld - end - pumped nd : yag laser sensor for displacement measurement has been investigated theoretically and demonstrated experimently, the results indicate that when the mean radius of pumping inside the laser cavity is far less than that of the oscilating laser mode, the exponential of the output power is a gauss function of the longitudinal positon of focused spot of ld pumping beam, both the measurement range and the sensitivity are dependent on the incident pumping power, as the incident pumping power is increased, the measurement range is enlarged and the sensitivity is improve d

    本文首先介紹了ld泵浦nd ： yag激光器的發展狀況、主要特性及其應用，從四能級速率方程出發，推導了ld泵浦nd ： yag激光器的閾值、輸出功率和斜效率的表達式，並簡述了激光器的工作原理、結構型式和倍頻方法；其次，以空間相關的速率方程為基礎，提出了ld端面泵浦nd ： yag激光器的設計方法，給出了一定泵浦耦合方式下，振蕩光模尺寸、最佳輸出耦合率、泵浦光模尺寸、泵浦光焦斑位置等參數的選取依據，以此為依據，設計了自聚焦透鏡耦合小功率ld泵浦nd ： yag激光器和透鏡組耦合高功率ld泵浦nd ： yag激光器，對激光器的輸出功率和功率穩定性等特性進行了實驗研究；再次，在帶尾纖輸出的高功率ld泵浦nd ： yag激光腔內插入一隻空液晶盒，觀察到了激光器以單縱模運轉；最後，根據泵浦光焦斑端面位置對激光輸出功率的影響規律，提出了ld端面泵浦nd ： yag激光位移傳感新方法，並進行了理論和實驗研究，研究結果表明：當激光晶體內泵浦光平均光斑半徑遠小於振西安理工大學碩士學位論文蕩光束腰半徑時，激光輸出功率的自然指數與泵浦光焦斑的縱向位置成高斯變化規律，測量范圍和靈敏度依賴于泵浦功率，隨著泵浦功率的增加，測量范圍擴大，靈敏度提高，當端面泵浦功率為7 . 24w （最大輸出功率為1 . 926w ）時，激光位移傳感器的測量范圍和靈敏度分別是13 . 045mm和0 . 148mw / pm 。

  5. The data used in the risk assessment of regional natural disasters imply the information not only on time but also on space. when the spatial information of the data is incomplete, it is necessary to optimize the data in order to reduce the error of the assessment. in the counterpart of the paper in last issue of the journal the theoretical investigation of the problem was carried out and the imcomplete information occured in risk assessment of regionalnatural disasters were class ifiedinto two types with treatment of interpolation model and correcting model res pectively. the former model is for insufficiency of the data and the later is for the case in which the accuracy of the data is not enough. inthispaper, taking the flood sustained by rural area plant in hunan province as an example, it is explained how to use the models to calculate. the models are examined as well

    區域自然災害風險評估中所用的數據不僅具有時間的意義，而且具有空間的意義，當數據的空間信息不完備時，需要對其進行優化處理，以減小風險評估的誤差，作者在本刊上一期的一篇文章中已進行了這方面的理論探討，將區域自然災害風險評估中所遇到的空間不完備信息分為兩類，分別用插補模型和校正模型進行了處理，插補模型是針對空間數據缺失情況的，而校正模型是針對空間數據不符合精度需要情況的，本文以湖南省農村種植業水災為例，進一步說明如何應用這些模型來進行計算，並對其進行了檢驗
  6. The conventional ways has low efficiency, which result in the application of overlap grid in moving - grid problem, which need re - disposes the interpolating connection in every step in time direction, is very difficult considering the computational efficiency. aim at the above problem in application of overlap grid, this paper using an new manner rooting in analysissitus to put forward a “ method of distinguishing points of intersection ” and develop corresponding computational soft, which could realize the automatic and shape - independent pre - disposal process for overlap grid. to deal with the problem of low efficiency for pre - disposal process in moving - grid, this paper bring forward the “ mosaic ” method and adt method which based on the huge memory of modern computer
