查询词典 surface patch

It was obvious that there is a thermal gradient between Central Business District and the countryside.In terms of the spatial pattern of the land brightness temperature,the most extensive UHI was distributed in Hankou,Hanyang and Wuchang.Urban heat islands distribution in Dongxi Lake,Caidian,Hannan and Jiangxia was scattered with some little heat islands.③ Interspersion and Juxtaposition Index and Percentage of like Adjacencies and Largest Patch Index were the most important factors that influence the land surface temperature.

结果表明武汉市土地利用类型的空间格局分布指数与地表温度有较好的相关性，其中地表温度与散布与并列指数、同类斑块相邻百分数指数和最大斑块所占景观面积比例指数的灰色关联度较高，说明地表温度的分布不仅受到各类型斑块与其它斑块相邻情况的影响较大，还受到最大斑块所占的总土地面积比例的影响。

It is to say that the patch of RAFT agent on the hairy chains.PS particles with the shell of copolymer of styrene and vinylbenzyl chloride were prepared by similar seeded and starved addition processes. RAFT agent with carboxyl end-group attached on the shell surface of PS particles by group reaction. Adding NIPA and photo-initiator into the continuous phase of polymerization system, hairy PNIPA were obtained.

最后，以表面负载一层乙烯基苄氯的亚微米级单分散聚苯乙烯微球为基质，将水溶性RAFT试剂与聚苯乙烯微球表面的官能团反应以负载到其表面，再在连续相中直接引入NIPA和光引发剂，RAFT聚合得到PNIPA毛发。

To fulfill the need of the application of RP technique in medical domain, reverse CAD modeling from medical cross sections is systematically studied in this dissertation. Firstly, Some algorithms related to the research of this dissertation are studied. New algorithms for orientation and inclusion test for simple polygon, an error constrained automatic faring algorithm for B-spline curve and a theorem regarding the termination criterion for subdivision of triangular Bézier patch are proposed. Then based on similarity between contours of adjacent sections, a methodology for surface reconstruction from cross sections is presented. Finally, a virtual measuring method is proposed.
