  1. Considering the influence of high evanescent modes, we have obtained the common theory. by the comparing between theoretical calculation and experimental data, we found the theory can accurately describe the high - frequency characteristic of this kind of slow - wave helical groove structure. then, five representative shapes are chosen and researched particularly ( triangle shape, cosine shape, trapezoid shape, rectangular shape and swallow - tailed shape )

    主要工作成果和創新之處在於: 1 .通過考慮高次模式的影響，獲得了一種更為精確分析任意槽形螺旋槽結構的普遍理論，經與實驗測量值比較，發現它更能準確可靠地描述此類螺旋慢波結構的高頻特性，然後詳細研究了五種槽形狀（三角形槽、餘弦形槽、梯形槽、矩形槽和燕尾形槽）對螺旋槽慢波系統導波特性的影響。
  2. Generally, the use priority is given to rectangular groove, and triangle groove is used under ultra - high pressure and ultra - high vacuum

    一般情況下優先使用矩形槽，只有在特高壓、特高真空的情況下才使用三角槽。
  3. To improve computing precision, the latter applies interpolating function of curved - quadrilateral element containing six npdes to thicking the influence surface of grillage. compared with lagrangian interpolation for rectangular element and triangle plane interpolation, this way not only improves computing precision but be more suitable for the curved - bar grillage analyzing method introduced this paper

    為了提高計算精度，本文應用六結點曲邊四邊形單元插值函數加密梁格影響面，與矩形單元拉格朗日插值及三角平面插值方法相比，不但提高了計算精度，且更適于曲桿梁格分析。
  4. The fresnel and franhufer diffraction patterns, of regular shapes screen such as slits, rectangular apertures, circle apertures, discs, triangle apertures, ronchi gratings, and some irregular shapes screen, are observed in the different propagation distance. this clearly gives the relation and difference of the two diffraction patterns

    具體分析了規則形狀如單縫、矩孔、圓孔、圓盤、三角孔、黑白光柵及一些不規則形狀等孔徑的菲涅耳衍射和夫瑯禾費衍射圖樣強度分佈，為深入理解菲涅耳衍射和夫瑯禾費衍射及其內在聯系與區別提供了理論依據。
  5. But a single b - spline surface can only represent rectangular topology type in essence. it is really a hard work that to generate smooth b - spline surfaces from arbitrary topological triangle meshes

    但由於b樣條曲面只能表示矩形拓撲的數據，所以將任意拓撲的三角網格數據轉換為b樣條曲面表示是一個比較困難的研究課題。
  6. Formulas of stresses in soil subjected to triangle distributing load on rectangular area beneath the surface of ground

    地基內豎向三角形荷載引起的土中應力公式
