In this paper, we provide an algorithm to detect the boundary points. Obviously, if a point is a boundary point, then its circumambient points will distribute only on one side or around a corner.

该算法能检测出点云数据的内、外边界特征点，同时对边界上的点进行排序，检测出边界特征点中的过渡点，最后构建点云轮廓的边界多边线。

Neoproterozoic Baoxing Complex in middle to lower metamorphic grade, located in western margin of Yangtze Craton, consists mainly of metamorphic gabbroic, dioritic gneisses, tonalitic and granodioritic gneisses, and massive monzogranites The studies of petrochemistry and SmNd isotopes of Baoxing Complex reveal that the gabbroic and dioritic magmas came from a congenetic magma derived from the partial melting of spinel lherzolites in depletive mantle, and that the magma was intensively contaminated by crustal materials during its emplacement The tonalitic and granodioritic magma were derived from the partial melting of metamorphic basalts in the lower crust And the monzogranitic magma was formed from partial melting of metagreywacks Integrating the lithological association, their trace elements, SmNd isotopic characteristics and petrogenesis, the Baoxing Complex must likely have been emplaced in an island arc tectonic background at the Neoproterozoic active continental margin of Yangtze Craton

位于扬子克拉通西缘的新元古代宝兴杂岩主要由中低级变质的辉长质片麻岩、闪长质片麻岩、英云闪长质到花岗闪长质片麻岩和块状二长花岗岩组成。岩石地球化学和SmNd同位素特征表明，辉长质片麻岩和闪长质片麻岩为同源岩浆演化序列，原始岩浆起源于亏损地幔尖晶石橄榄岩的部分熔融，在上升和侵位过程中受到了地壳岩石强烈混染。英云闪长质和花岗闪长质岩浆形成于下地壳玄武质岩石部分熔融，而二长花岗质岩浆形成于杂砂岩的部分熔融。综合分析宝兴杂岩的岩石组合、微量元素和同位素特征，该杂岩体最有可能形成于新元古代活动大陆边缘火山弧构造背景，并可能经历了碰撞过程。

objective to confirm the optimal harvest age and cultivating condition, and provide theoretic knowledge for the planting of coptis teeta wall.

目的 确定云连的最适宜采收年限和栽培技术，为今后云连生产提供理论依据。

Mr. Li, born in 1982 in Chongqing, China, has been a precious antidote to the wildly popular, although crassly unidiomatic and unmusical Lang Lang, also a Deutsche Grammophon pianist.

李云迪1982年出生於中国重庆市﹐相对於同样签约在Deutsche Grammophon门下的另一位中国钢琴家郎朗那种取悦大众、但却极为平庸粗糙、毫无艺术感可言的风格﹐李云迪的演奏一直都在维系一块宝贵的净土。

Four Polystictus versicolor strains such as PVC0,PVC1,P VC2 and PVC3 were examined for their ability to decolorize refinery effluent, which contains Melanoidin, HADP'S and Caramel.

比较了 4株不同云芝菌PVC0、PVC1、PVC2和PVC3对含有美拉德反应色素、碱降解色素及焦糖色素的模拟废水的生物降解脱色能力及云芝多糖生产能力。

The tidal flats include dolomitic flat, limemud flat and dolomitic-limemud flat, whereas the open platform mainly consists of grain banks and reefs.

其中，潮坪环境包括云坪、灰坪、灰云坪等，而开阔臺地环境为各种颗粒滩和生物礁。环境的演化反映了从早到晚海水逐渐加深的过程。

Using methods of sedimentary and geochemistry, this paper analyzed the sedimentary environment in the Majiagou Formation. It suggests that Member 1, Member 3 and Member 5 are characterized by a dry and hot climate as well as fall of the sea level. The area of Well Longtan 1 in the eastern basin is abundant of platform evaporites with the depositional anhydrite and salt rock, surrounded by a suite of dolomite intercalated by the thin layers of anhydrite from the anhydrite\|dolomite platform sediment. It deposits muddy dolomite, dolomitic limestone and fine\|grained dolomite in the limestone-dolomite platform and restricted sea.

运用沉积学与地球化学方法，分析了研究区马家沟组的沉积环境，认为：马一段、马三段和马五段沉积时期气候干热，海平面下降，盆地东部龙探1井区一带主要为台地蒸发岩相沉积，发育了膏盐岩和盐岩沉积，其周边则发育了一套白云岩夹薄层硬石膏岩的含膏云坪相沉积，在盆地东部周边地区主要沉积了泥质白云岩、白云质灰岩和细晶白云岩的云灰坪和局限海相沉积。

Yamaxun is at opening a name to developer last year " elastometer calculates machine cloud " service, IBM also is rolled out " La Yun " plan.

亚马逊于去年向开发者开放了名为&弹性计算机云&的服务，IBM 也推出&蓝云&计划。

The physiological and biochemical resistant mechanism of tea cultivars to tea brown blight caused by Guignardia camelliae. Making use of the mensuration of spectrophotometric analysis to study the enzyme activity of Peroxidas, Polyphenol Oxidas, Catalas, Phenylalamine Ammenia-lyase. The result showed that there was definite difference to the metabolic rule of defence enzymes activity in the annual leaf tissue of the resistant and susceptible cultivars after infecting.

茶树抗云纹叶枯病的生理生化机理研究利用分光光度计对茶树叶片中过氧化物酶、多酚氧化酶、过氧化氢酶，苯丙氨酸解氨酶的活性进行了测定分析，结果表明：感染茶云纹叶枯病菌前后，抗病品种和感病品种当年生成叶中防御酶活性变化规律存在一定的差异。

From analyzed two typical flashes, we find that the early stage of the intercloud discharge process is similar to the PBP process of normal CG discharge.

两次闪电的个例分析发现该云内放电过程的前期类似于常规地闪的预击穿过程，可能起始于云中部的负电荷。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
