We carried out the research in famous brands in the beginning of 1990s and have established a theoretical system after ten years " research . however , sometimes we still do the superficial and repeated work 我国对名牌的研究起于20世纪90年代初，经过10年的研究已构筑了一定的理论体系，但还是难以摆脱表层的重复工作。
Dual - action toothpaste with xylitol and baking soda to remove stains and surface discolouration from teeth . leaves teeth sparkling white and mouth minty fresh . suitable even for sensitive teeth 这种双重作用的牙膏，含有木糖醇和小苏打，能清除牙齿表层的污垢和污色。用后，牙齿显得更洁白亮丽，而且满口清香。敏感性的牙齿亦适用。
Except for the cache manager , which happens to be part of openafs - curiously only running with ext2 as an underlying file system - the basic superficial structure of openafs resembles modern nfs implementations 缓存管理器碰巧是openafs的一部分，很奇怪，它只作为底层文件系统与ext2一起运行。除缓存管理器之外， openafs表层的基本结构很像现代的nfs实现。
The final group of 45 workers brought out through an auxiliary shaft normally used to remove debris arrived at the surface shortly before 9 p . m . , walking out caked in dust but otherwise healthy a day and a half after the accident 最后的45名工人于晚上9点前通过平时用来运输碎屑到表层的后备轴被救出.在一天半的事故中,每个人都铺满灰尘,但是值得庆幸的是都很安全
The results indicated that even if there was different at initial soil condition , such as initial moisture content and initial salt content , salt content in soil profile and sar at top soil increased greatly after the high salinity water infiltrated 结果表明尽管土壤初始条件存在差异，但灌高矿化度水后，土壤含盐量和溶液浓度总体增加，且土壤剖面特别是表层的sar明显增大。
Otherwise , how will i know if my method works or not ? incredibly , just after he finished cultivating his land , rain came to his area . it was not very heavy , but the water managed to penetrate the topsoil , and held together the dry surface soil and the wet soil beneath 奇怪的是，他刚种完地就来了一场雨，雨虽然不大，但渗透地面之后，总算把表层的乾土和地下的湿土结合在一起了。
2 . the arc erosion of cuw70 / crcu integrated contact is first from the even volatilization of the surface cu , following by the formation of a w shell on the surface of w skeleton , then the shell flake off , after this , new arc erosion occur ( 2 ) cuw70的烧损先是表层的cu均匀挥发，接着在骨架的表面形成一层以w为主的壳层，然后壳层剥落，裸露出来的继续烧损，如此反复，导致了触头的烧损。
We found via literature searches that the academia just recorded the surface layer signs of wang - huo , a kind of national folk - custom cultural relic which disappeared rapidly and deserved to collect , protect and record , without deep - seated attention and research 通过文献检索发现,学界对旺火这种正在迅速消失的、具有收集、保存和记录价值的“民族民俗文物” ,大多仅记载了其表层的文化符号,缺乏深层的关注和研究。
Abstract : this paper discussed the physicalmetallurgical process during laser hardening withsteel and cast iron , presented the technique designprinciple of laser hardening to achieve good resultsit also introduced the inspection method for laserhardened surface of steel and cast iron 文摘:讨论了钢和铸铁在激光表面淬硬时的物理冶金学过程，提出了激光淬硬获得优良效果的工艺设计依据，介绍了对钢铁零件激光淬硬表层的检验方法。
The rapid evolution may be the result of the dwarf ' s innards mixing poorly , leading the star to burn only the fuel close to its surface , which would quickly run out , hypothesize university of manchester researchers in the april 8 science 根据英国曼彻斯特大学的研究人员，在2005年4月8日的《科学》上所提出的假设，演变的过程之所以如此迅速，或许导因于白矮星那先天不良的内部对流，让它只能燃烧靠近表层的燃料，这样一来当然撑不了多久。
