  1. Firstly, the surface characteristic of polystyrene particle is changed from water detesting to water intimity by using special techniques and admixtures so mat the compound quality with inorganic materials is insured. secondly, the contradiction between the weight and strength is solved through optimizing the particle size and using composite fiber and the best heat conductivity is achieved under the condition that the necessary strength is met. in the research process, the author solved the problem of fiber dispersing in insulating materials so that the contraction of the material is controlled

    課題研究中，首先採用特殊的改性工藝及外加劑實現對聚苯乙烯顆粒表面的成功改性，使其表面由憎水轉化為完全親水，確保與無機材料的復合質量；其次，通過採用優化骨料級配及使用復合纖維等措施解決了保溫材料的輕質與強度的矛盾，使保溫材料在滿足必要的強度的前提下，導熱系數降至最小；並且，課題研究中成功解決了纖維在保溫材料中均勻分散的問題，達到了抑制保溫材料收縮的目的；最後，通過採用復合外加劑、合適的膠凝材料及合理的配比等措施確保該保溫材料具有良好的和易性，滿足施工的要求。
  2. Shoe - size adjustment of claw tray uses left and right claw trays to make parallel contraction and enlargement to both sides. the left and right claw tray can turn and move singly. the adjustment is accurate and quick, so that it avoids angles creation among cloths gaps

    爪盤鞋碼大小調整縮放：採用了左右爪盤同時向兩側平行縮放，左右爪盤也可單獨轉動移動，調整準確快速，並可預防布縫間隙產生角。
  3. The smaller the ratio of nh3 / teos is more helpful for the synthesis of samples. the contraction from calcination of samples obtained in eda medium is proporational to the ratio of eda / teos at room temperature. the samples obtained in mixed basic media ( naoh / tea ) have thicker wall and more thermal stability than in naoh medium, but pore size is smaller correspondingly

    氨水介質中， nh _ 2 teos值在（ 8 ， 25 ）之間越小，越有利於mcm - 41的室溫合成；室溫條件下eda介質中得到樣品的燒成收縮量與eda teos的值成正比;與naoh介質相比，混合介質（ na0h三乙醇胺）中水熱合成的樣品具有較厚的孔壁，有著更好的水熱穩定性，但同時孔徑相應較小。
  4. These cells can be kept alive up to 1 week in 10 % pcs rpmi 1640 medium, the cell contraction or size - minimized was determined after 5 days of culture and these cells began to fall from the bottle wall after 1 week. consequently, the hepatocytes died or were replated by nonparenchymal cells

    在普通培養液中的肝細胞生存時間可達5 7d ，之後細胞回縮，體積變小，逐漸死亡並且從培養瓶壁上脫落下來，或者出現其他肝臟的非實質細胞優勢生長的現象。
