surface detection meaning in Chinese
用地面器材探测
Examples
- Asde , airport surface detection equipment
空港面探知装置 - With the development of high way , the research and developing of high way road surface detection system is very exigent
随着我国高速公路建设的飞速发展，高速公路路面病害自动检测系统的研制显得尤为迫切。 - The paper points out that different material must be imitated through different methods . in the paper , the standard material is imitated by using illumination model , and the non - standard material is imitated by using texture and illumination model . last , using the realistic image synthesis technique , material function and the rendering technique , i realize the scene modeling , projection transformation , visible - surface detection , illumination model and surface rendering in this paper
其次，根据材质属性的不同将材质分为标准材质和非标准材质，并且根据材质的不同属性而采用不同的方法进行模拟，对标准材质，如铜、铁通过光照明模型技术来模拟；对木材等非标准材质通过纹理映射技术来逼真的模拟，并分析总结出模拟各种材质的经验模型，即一个初步的纹理生成函数，在此基础上对函数进行了数学演变，最终建立一个比较完善的纹理生成函数，并且对函数中的主要影响因素进行了分析。 - Furthermore , the growth and the study of self - organized quantum dots structures become more and more important recently , and the application of self - organization technique become wider and wider in this thesis , we address the theory of film growth and the growth technique firstly more , the ways and characteristics of surface detection are prescribed we mainly report the growth process , results and discuss of self - organized quantum dots structures in the a12o3 substrates by s - k mode using ecr - mocvd , in the espd - u device the growth art of ain epilayer which is the preliminary foundation of self - organized gan / ain quantum dots structures , including the substrate cleaning , nitridation , the growth of buffer and the growth of gan and ain epilayer , is discussed we deliberately compare the test result of rheed xrd and afm and achieved the optimalized condition of ain at last we have successfully realized the growth of ain which is much smooth and better crystal quality moreover , we grow the self - organized gan / ain quantum dots structure in s - k mode because the limits of the heater temperature , we can not grow the atom - smooth epilayer of ain until now so we could not grow better quantum dots which have small diameter and big density but the self - organized quantum dots structures with better quality will be realized successfully if the substrate temperature is increased the thesis study belong to my tutor subject of national nature science foundation ( 69976008 )
本论文主要论述了在espd - u装置上，采用电子回旋共振等离子体增强mocvd ( ecr - pamocvd )方法，在蓝宝石衬底上通过s - k模式自组装生长gan aln量子点结构的生长工艺、结果及讨论。而重点分析了自组装生长量子点之前的aln外延层生长工艺，包括衬底清洗、氮化、缓冲层的生长和gan 、 aln外延层的生长；通过高能电子衍射、 x射线衍射和原子力显微镜测试，并且对这些测试结果进行了详细的比较研究，得出了较优化的工艺条件，生长出了晶质较好、表面较平整的aln外延层；进而采用s - k模式自组装生长了gan aln量子点结构。由于实验装置加热炉温度的限制，我们没有能够生长出原子级平滑的aln外延层表面，因而没能够生长出密度比较大和直径比较小的量子点。
