  1. The variation of db magnitude attenuation and phase delay of reflection is uniformly proportional to distance along the line toward the direction of reflection, where the phase delay is 360 degree per wave length, the db attenuation per meter is twice the one way db attenuation per meter of forward or backward wave

    沿傳輸線之反射，即反向傳播與正向傳播電壓沿傳輸線之相量比，其相位落後及分貝衰減沿反射方向之變化則正比于線長，相位落後為每半波長三百六十度，每米之分貝衰減為正向波或反向波單程每米之分貝衰減之兩倍。
  2. In this paper, we not only analysed the different effects of the disturbing gravitation on the trajectories of different ranges, but also discussed shortcomeings of the spherical harmonics model by which the external gravitation potential of the earth is shown usually. when the model is applied directly to the calculation of the trajectory, since the recurrent calculation can not be avoided, an increase in orders of model will result on a decrease in the speed of calculation

    本文重點分析了擾動引力對不同射程導彈的落點偏差的影響，並且討論了原有計算擾動引力的球諧函數法在計算速度上的缺陷（由於勒讓德函數的遞推計算，使得隨著模型階數的增加模型的計算速度下降） ，然後對其進行改進使其能更好的適用於彈道計算。
  3. Ae testing technology, which is used more and more widely for solving the problems, expensive and long inspecting periods in general testing, is only adopted by the skilled inspector now for behindhand testing system, high orientation error and low quality orientation software. in addition, orientation error is very high in global vessel testing, also the software can not show location picture in three - dimension, all of these restrict the development of the ae technology. in the aspect of testing system, the vallen corp

    為了解決常規檢測維修費用昂貴，周期長的問題而興起的聲發射檢測技術，因為檢測儀器的相對落後及軟體的定位誤差較大，同時達不到可視化要求，到目前為止還只局限於有此技術且經驗豐富的工程技術人員使用，另外定位特別是對球罐缺陷點的判斷誤差偏大，而且不能立體的展示定位結果，給聲發射技術的發展及推廣帶來很大的障礙。
