  1. The observations showed that there were a lot of starch grains in the chloroplasts of alpine plants, and the starch grains were usually round or oval in shape arranged along the longitudinal axis of chloroplasts

    結果發現，在所研究的5種高山植物葉綠體中，澱粉粒數量均較多，澱粉粒呈長橢圓形或圓形，沿葉綠體長軸分佈。
  2. The paper analyzed the struture of the tri - eccentric butterfly vavle at length, defined the tri - eccentric butterfly valve, educed the geometry function and its characteristic about the section of the butterfly disc. the results indicate : the parallel contour line across butterfly disc thickness is normal ellipse, thereby eslablished function relations between its geometry parameters ( long axis and short axis ) of three primary sections of the butterfly disc and the tri - eccentricity ; in order to avoid interference between the butterfly disc and the valve seat as well as the valve body, combining the torque, we obtained the feasible range about the rotation center of the tri - eccentric butterfly vavle

    本文主要分析了三偏心蝶閥的結構，給出了三偏心的定義，推導出了蝶板截面的幾何方程及其性質，結果表明，沿蝶板厚度的平行截面輪廓線為標準的橢圓形，進而推導出了蝶板幾個主要截面的幾何參數（長軸、短軸）與三個偏心之間的函數關系；考慮到蝶板啟閉過程中避免與閥體及閥座發生干涉，結合蝶板的啟閉扭矩，確立了三偏心蝶閥回轉中心的適宜區域。
  3. The optimization design of the crank - connect rod mechanism was carried out. collocating the mass reasonably, adjusting the ratio ( ( 1 - f ) / f ) of the long axis to the short axis of the ellipse track, adjusting the direction of long axis to the direction where the internal - combustion engine was not sensitive to the stimulating force. all the above contribute to the max reduction of the vibration

    對單缸內燃機的曲柄滑塊機構進行優化設計，合理的布置加配質量的大小和方向，對軌跡橢圓的長短軸比率（ 1 - f ） / f進行調整，將長軸方向調整到內燃機對激振力不敏感的方向，從而使不平衡力對內燃機所產生的振動最小，以某一具體的單缸內燃機為例進行了計算分析。
