The main differences in chemical compounds related to the taste and flavorbetween cultured and wild prawns may be summerized as follows: 1 The content of quaternary bases in the extractives of wild prawn is higher than that of cultured prawn; 2 The content of fatty acids, C18:2ω6 is higher in the cultured prawn; 3 Many thiazole compounds were found in the odor concentrate of cultured prawn, azulene was found in the odor compounds of wild prawn; 4 The textrue of cultrued prawn meat is relatively weak.

综上所述，养殖对虾与天然对虾的尝味比较中主要差别是提取物组分的有机碱；对虾肌肉脂质比较结果是养殖对虾肌肉脂质中C18：2ω6含量特别高；对虾挥发性成分结果是养殖对虾中有大量的噻唑化合物，天然对虾存在薁类化合物；两类对虾质地比较的结果是养殖对虾质地不及天然对虾。

Natural diamonds often exist in the Kimberlite pipes of the mantle, where often contain the inorganic elements--- sulfur. So the inclusions of natural diamonds are always carbonate minerals and sulfide. Undoubtedly, the study of the additive sulfur action in the course of synthesizing diamond will further our understanding the reason of natural germ formation.

天然金刚石多产生于地壳中的金伯利岩和钾镁煌斑岩，该岩层中含有非金属元素硫，天然金刚石中的包裹体通常为硅酸盐矿物和硫化物[41]，因此研究添加剂硫在合成金刚石中的影响是认识天然金刚石成因的重要方面。

The method includes the following steps: getting specific amount of knitted or unknitted natural fiber and dipping the natural fiber in the aqueous solution of silane coupling agent for 1-100min, taking out and drying the natural fiber, thus producing natural fiber with modified surface; then pressing the polylactic acid into sheet in a plate vulcanization machine; disposing 2-10 polylactic acid sheets into a die and arranging one modified natural fiber sheet between every two polylactic acid sheets; pressing and molding the sheets; in this way totally biologically degradable polylactic acid composite material can be made.

该方法为：先取一定量的经过编织或未编织天然纤维，将其浸渍在偶联剂水溶液中1～100分钟后取出，经干燥后得到表面改性的天然纤维。然后，将聚乳酸在平板硫化机中压制成薄板；将2～10片聚乳酸薄板放在模具中，且每2片之间放置1片改性的天然纤维，然后模压成型，得到可完全生物降解聚乳酸复合材料。
