A part of microbial cells would autolyzed to release the intercellular alkanedegrading enzymes when they were cultured on alkane. Thus alkane could be degraded and synthesized alkane derivative with surface activity extracellularly. This surface-active agent would improve alkane emulsifying, and those unautolyzed cells could utilize the emulsified alkane sequentially.

微生物细胞在烃类基质中培养时，为了适应其疏水性环境以更好地摄取烷烃，会通过一部分细胞的自溶解体而使得胞内烃类代谢酶等释放，这样烃类在胞外被代谢生成具有表面活性的烷烃衍生物，该表面活性产物将促进烃类的乳化，使得剩余的未自溶解体的细胞可以借助生物表面活性剂而摄取降解烃类。

Toggle the Material Drop Surface button to the All Surfaces mode so you can drop a material onto the faces, edges and bevels of the fins all at once.

切换&材质丢弃表面&按钮到所有表面模式，这样你能够立即丢弃一个材质到这几个鳍片的所有表面、边缘和倒角上了。

According to Maxwell' geomorphology theory and the standardization characteristic of surface texture feature based on GPS'(geometrical product specification) areal method, deeply research the change tree and Wolf pruning technology which were used in analyzing surface topography. Further standardized the Wolf pruning standard of area, line and point feature etc and the quantification parameters of charactering surface texture.

Firstly, we investigated the mechanism of material removal and formation of super smooth surface in CMP. And the material removal mechanism of CMP at atomic level was described. The comprehension and hypothesis of material removal mechanism of super smooth surface polishing were enunciated. For instance, we circumstantiated material removal mechanism and formation of super smooth surface in CMP of LBO crystal.

化学机械抛光是超精密加工技术中最重要的方法之一，作者首先调研化学机械抛光的材料去除和超光滑表面形成机理，研究原子级材料去除机理，提出对化学机械抛光材料去除和超光滑表面形成的理解；并以LBO晶体为例详细描述化学机械抛光过程中材料去除和超光滑表面形成。

The results show that the concave structure ameliorates the surface stress distribution of the non-smooth sample, makes the local stress between concaves less apparently than that of the smooth sample, that means the local low stress areas are formed on the non-smooth surface.

结果表明：在受力状态下，仿生非光滑凹坑改善了试样表面的应力分布，使非光滑试样表面凹坑间的区域局部应力明显小于光滑试样表面的应力，即产生了局部低应力区。

The physical ways are blending, surface adsorping or coating. The chemical ways are copolymerizing, crosslinking and surface modifying, all of which endow bioactivity on PLA by changing the polymeric macromolecule structure or surface structure.

物理法主要通过共混、表面吸附或涂层等实现对聚乳酸的生物活化；化学法包括共聚、交联、表面修饰等，通过改变聚合物大分子或表面结构赋予材料生物活性。

The crocking resistance of coatings film is tested by use of adhesive tape, sticking off or peeling off of the marks painted with waterborne or solventborne marking pens.

结果发现表面粗糙度和表面助剂的共同作用可有效防止记号笔对涂层的粘结，粗糙表面的涂层亲水、亲油性对抗粘结作用有较大的影响，涂膜在水浸泡前后的抗粘性效果表现不同。

The oxide on the surface can be deoxidized by H2 at high temperatures under certain conditions,which establishes a foundation for the repetitive use of CdTe source.

结果表明：多次使用后的CdTe源表面有变黄的趋势，源表面有CdO粉末的存在，经H2在一定条件的高温还原，可以去除表面的氧化物，为源的重复使用奠定基础。

Methanol dissociates to CO and H on platinum electrode, on which CO is strongly adsorbed and accordingly becomes a detrimental intermediate.

甲醇在铂电极表面的脱氢生成CO强烈吸附在铂电极表面，阻碍了甲醇在铂表面的化学吸附，导致催化剂中毒。
