  1. Our research analyzes comprehensively the sand data, such as thickness distribution, velocity distribution, frequency distribution of sand incipience velocity, expatiates the behaviors of these two sand incipiences in wind - blown - sand flow, then our research amends some deficiency of relative researches

    本文全面分析了沙粒濃度分佈、速度分佈和沙面上起動沙粒速度參數的頻率分佈等,闡述了兩種沙粒起動方式在風沙流中的不同表現,並對相關研究資料中的不足進行修正。
  2. Results showed that, attribute data obtained by this way avoided deficiency of polygon overlap way, as a result, the logistical consistency between map data and attribute data reached over 90 % on average. database pivot precision was 0. 18mm, data quantity during manipulation was decreased greatly, data treatment was more convenient, computation velocity was boosted greatly. workload of map and table pretreatment and edition was mitigated on large scale, spatial data precision was increase

    研究表明:用該方法獲得的屬性數據,避免了多邊形疊加方法的不足之處,能使圖形數據和屬性數據邏輯一致性平均達到90以上,數據庫點位精度達到0 . 18mm ,且操作中圖層數據量大大減小,數據處理更為方便,運算速度大為提高;減輕了圖表預處理和編輯的工作量,使空間數據精度提高。
  3. Using the 2 - dimension numerical control machining flat and dual galvanometer scanning system is to enlarge marking scope and to make up the shortcoming of slow marking velocity of immovable mode and deficiency of small marking scope of movable mode. this method is fit for the situation of larger scope, which improves produce efficiency
