    固態化后，用一白金絲蘸取小量細菌細胞接種在明膠表面上。
  2. Picking up and analysis of the surface myoelectric signals of respiratory muscule

  3. Applying the above - mentioned method, the author developed an approximate developing - mapping system based on catia v5 using vb, realized the development computing of panel surface and auto - drawing of developed shape in catia, dealt with the problem : getting mesh data from analysis & simulation module of catia, picking up structure information data in iges, showing 2d developed model in catia

    應用上述幾何展開演算法，作者基於windowsnt 2000 xp系統和catiav5平臺用visualbasic開發了一套「不可展曲面近似展開和內部結構信息映射系統」軟體，簡稱demaps系統，實現了飛機壁板類零件的展開計算和展開圖形自動繪制。
  4. But the standard mc has some shortcomings : firstly, the standard mc picks up isosurfaces by threshold, however, threshold segmentation is invalid for picking up tissues or organs from some medical images ; secondly, the standard mc pocesses cubes one by one, that is to say, all the cubes will be checked, and the algorithm spents 30 % - 70 % of time to check the null units, so we need a reasonable data structure to travel the space data and accelerate the checking or filting of null units ; thirdly, the standard mc has a large scale of triangles, normally, the tissue or organ reconstructed includes hundreds of thousands so much as millions of triangles, this means it hardly to execute real - time rendering or interaction ; lastly, the standard mc can not get the very smoothly surface mesh, and there will be some unexpected accidented cases, especially in the case of big errors in oringinal data

    但是標準mc演算法存在較大的問題:標準mc演算法實質上是通過閾值分割來提取等值面，閾值分割對某些醫學圖像的組織或器官的提取難以得到較好的效果;標準mc演算法是逐個移動立方體來進行處理，就是說對所有的立方體都要進行一次檢測，演算法執行中30 % ~ 70 %的時間用在對空單元的檢測上，因此需要有一種合理的數據結構對空間數據進行有效的遍歷，以加速對空單元的檢測和過濾;標準mc演算法產生了大量的三角面片，一般重建的組織或器官包含數十萬甚至上百萬的三角面片，難以實現實時的繪制和交互操作;標準mc演算法得到的表面網格並不光滑，會有一些不期望的凹凸，特別是在原始數據有較大誤差的情況下尤其突出。
  5. Geographic information system ( gis ) is a spatial information system which tasks are picking up, storage, administration, analysis and description of all or part of earth surface data ( including atmospheric layer ) related to spatial and geographic distribution

    地理信息系統（ gis ）是一種以採集、貯存、管理、分析和描述整個或部分地球表面（包括大氣層在內）與空間和地理分佈有關的數據為主要任務的空間信息系統。
  6. 4 picking up the tiles, applying 1 : 2 cement paste or 1 : 0. 15 cement and lime cream onto the binding surface of the tiles, then constructing onto the floor

    時，宜用1 : 2水泥漿或1 : 0 . 15水泥石灰膏漿均勻抹于鋪貼面，再用均勻力鋪在地面之
