  1. ( 2 ) the causation that the caustic phenomena of electromagnetic wave propagation in two - dimension concave reflectors occurs and the types of singularities in caustic fields are investigated, and the conclusion that there are two types of singularities ( fold and cusp ) in caustic fields in two - dimension concave reflectors is obtained ; by symplectic geometrical method, formulations of computing wave fields in and far away from caustic fields in two - dimension concave reflectors are deduced, and the results are plotted in pictures. ( 3 ) the cause of the caustic phenomena of electromagnetic wave propagation in three - dimension concave reflectors and the types of singularities in caustic fields is discussed, and the conclusion that there are three main types of singularities ( fold, cusp and swallowtail ) in caustic fields in three - dimension concave reflectors is obtained ; by symplectic geometrical method, the formulae of computing wave fields in and far away from caustic fields in three - dimension concave reflectors are deduced. particularly, the wave fields in ellipsoid concave reflector are computed, and the results displayed in special sections are given

    論文主要包括三個方面： （ 1 ）分析了凹面反射的焦散現象，給出了不同凹面反射的焦散圖； （ 2 ）分析了二維凹面反射波動場焦散現象產生的原因及焦散區奇性的種類，得出了二維凹面反射波動場焦散區奇性主要有折疊（ fold ）和尖點（ cusp ）兩種的結論，利用辛幾何方法構造了圓錐曲面反射波動場非焦散區和焦散區的通用計算公式，並給出了圓柱面、橢圓柱面及雙曲柱面反射的計算結果； （ 3 ）分析了三維凹面反射波動場焦散現象產生的原因及焦散區奇性的種類，得出了三維凹面反射波動場焦散區奇性主要有折疊（ fom 、尖點kusp和燕尾k ）三種的結論，提出了利用辛幾何方法計算三維凹面反射波動場非焦散區和焦散區的計算方法，並給出了三軸不等橢球體凹面反射波動場的計算結果剖面圖。
  2. The reflector can increase the neutron flux obviously and the main processes of the neutron yield in reflector are spallation reaction induced by energetic hadrons and ( n, 2n ) reaction. when the moderator height is equal to the distance between the upper part and the lower part of the split target, the total neutron flux of the split target will be higher by 20. 1 % than that of the integral one. secondly, the high - energy neutron escaping from the target will enter into the moderator and be slowed down

    得到經水慢化器慢化后，中子通量在慢化器厚度與高度方向上的分佈；比較了水與液態氫的慢化能力以及中子在水、液態氫、液態甲烷這三種慢化器慢化后的能譜；在csns的靶站設計中，引出慢中子的導管不完全位於慢化器中子引出面的法線方向上，因此進一步計算了中子通量角分佈。

  4. In this paper, the vacuum thermo - cycling effects and vacuum ultraviolet effects on space inflatable structural materials were analyzed based on a thorough survey over the studies done through flight tests, ground simulation experiments and theoretical research. the main contents of this thesis are as follows : the performance damage effects of thermo - cycling on space inflatable structural fabric carbon fiber reinforced epoxy laminates ( cf / ep ), aluminized kapton ( al / kapton ) films which used as reflector of space inflatable antenna were investigated by a temperature range of - 120 120 with the vacuum degree 10 - 5 pa which conducted with space environment ground - based simulation facility

    本文在對國內外飛行試驗、地面模擬試驗以及理論研究等所取得的成果調研的基礎上，針對空間充氣結構材料進行地面模擬真空熱循環與真空紫外輻照的研究工作:利用真空熱循環地面模擬試驗機研究了真空環境（ 10 - 5pa ）中- 120 120的熱循環條件下空間充氣支撐結構織物碳纖維增強環氧樹脂（ cf / ep ）層合材料、空間充氣展開天線反射面鍍鋁聚酰亞胺（ al / kapton ）薄膜的空間環境效應。
  5. Clk - proliferation cyclone applicable to the collection of non - fiber drying of granular dust is the main characteristics of a conical dongshen, thus reducing the dust since the dongshen gas exports to the centre to short - circuit the possibility and install a conical reflector screen to prevent the two air separation will have to roll up the dust down, brought out by the increased flow, thereby enhancing the efficiency of dust

    Clk擴散式旋風除塵器，適用於捕集乾燥的非纖維性的顆粒狀粉塵，主要特點是筒身呈圓錐形，因而減少了含塵氣體自筒身中心短路到出口去的可能性，並裝有圓錐形的反射屏，防止兩次氣流將已經分離下來的粉塵重新捲起，被上升氣流帶出，因而提高了除塵效率。
