  1. Abstract : from a universal formula for calculating the attenuation cross section of particles in arbitrary shapes, exact expressions for calcualting the attenuation cross section of polydisperse, small spheroids, whose rotary axes are in specific status, have been derived. attenuation cross sections of both liquid and ice particles in different shapes at different wavelengths in microwave band have been computed and analyzed. the results are informative to microwave remote sensing of precipitation

    文摘:從計算任意形狀粒子的衰減截面普遍公式出發，推導出了小旋轉橢球粒子群旋轉軸處于不同狀態時的衰減截面函數表達式，並計算分析各種狀態下衰減截面隨降水粒子相態、形狀和入射波波長的變化特徵，所得結果可用於降水微波遙感。
  2. It is based on the principle : under a number of angles, the x - ray attenuation in a cross section of a human body is measured by detector resulting in a set of profiles. this set of profiles is called the radon transform of the object in mathematics. the problem now is to reconstruct a two - dimensional image via inverting its radon transform

    它所基於的成像原理是：人體的某個剖面在若干個角度上被x射線束照射，照射后x射線的衰減量被檢測器記錄下來，形成投影集合，數學上將這個投影集合描述為該剖面的radon變換，通過反演radon變換就能夠重建剖面的二維圖像。
  3. Computerized tomography ( ct ) is a typical non - invasive examination techniques in medicine, which can depict anatomical structures without damaging the human body. lt is based on the principle : under a number of angles, the x - ray attenuation in a cross section of a human body is measured by detector resulting in a set of profiles. this set of profiles is called the radon transfoim of the object in mathematics. the problem now is to reconstruct a two - dimensional image via inverting its radon transform

  4. This algorithm uses the profiles collected from a number of angles to compute the x - ray attenuation coefficient of a cross section inside the body, then reconstruct the image of the cross section

    該演算法利用從各方向測量出來的投影值求出物體內部受檢斷面各點的x射線衰減系數，從而重建出整個人體橫截面的圖像。
