By analyzing the characteristics of the boundary pixels to formulate a boundary pixel extraction operator, the operator need only calculate up to 4 pixels neighborhood pixels, is efficient, fast, he can direct the use of binary images are extracted as the boundary pixel, are single-pixel wide border.

通过分析边界象素的特征，归纳出一个边界象素提取算子，该算子最多只需要计算象素的4邻域象素，运算量小，速度快，运用他能直接提取出二值图象的边界象素，得到单象素宽的边界。

Meanwhile, the collapse of the north flank had coalesced into the largest avalanche in recorded history, surging 23 km (13 mi) down the North Fork of the Toutle River at speeds 300km per hour (180 mph) and burying the valley under 45m (150 ft) of a hummocky mixture of rock, mud, and glacial ice.

同时，山体北侧的崩溃加入了有史以来最大的火山灰雪崩，波涛汹涌般地顺着图特河的北支流流过23公里（13英里），速度达到每小时300公里（180英里），整个山谷被高45米（150英尺）的岩石、泥浆和冰块混合物形成的小山丘所淹埋。

We prove that $2$-degenerate graphs, Halin graphs, graphs with maximum degree at most 3 and graphs with $d_{min} leq 1$ are fully orientable.

Use CORELDRAW with version, to increase the speed if the file is bigger, with more graphics version, it is a couple of small version of the base map in one piece, the amount of information to reduce the file, improving output speed, note the text not to bitmaps such as text converted to bitmap will affect the accuracy of the text.

诳骗CORELDRAW联版时，为提矮速率如果文件比力不小，联版的图形比力众，最坏不兵几个小版的底图分为一张，减小文件的陈闻度，提矮输入速率，夺目笔墨不给转成位图如笔墨转为位图不兵感化笔墨的精度。

Packaging business card printing and membership card making enterprise problem is different, the CTP does for packing business card printing and membership card making high-quality printing, such as mesh point of reducing passbys can be produced by more than the traditional print version of dot, richer figure, image level, so that the packaging business card printing and membership card making quality be increased; the digital prepress production once-version, eliminating film at work affected by environmental pollution by dust, so that the printed matter almost no stains, suites a cleaner, clearer, and so on, these advantages, there is no dispute, but the point is, since the packaging business card printing and membership card making products with other color business card printing and membership card making products product characteristic of the existence of a certain amount of difference, is targeted at users of the product quality requirements there are differences, as opposed to traditional prepress production, CTP and could not make the packaging of quality drastically improved, more specifically, this investment can not be brought in a chip based on such an idea, a lot of packaging business card printing and membership card making business-to-there is currently no intention of buying the CTP, and some even think that C under P on packaging business card printing and membership card making enterprise is the only additions to make amends for whitly the number but need to.

包装制卡和会员卡制息企业所沉思的题纲不离有所不同了，CTP不实能为包装制卡和会员卡制息不求应矮品格的印版，比如网不背还原性较好，能爆不收比古板印版更锐冻的网不背、更丰裕的图，的图象条理，从而使包装制卡和会员卡制息品格度获得提矮；印后数字冻不入产一次不败版，制止了胶片在处事洋施境况尘埃的浑浊，使印品实在无不净不背，版背更肮脏、更澄辉等，这些劣势是操纵任何争议的，但关脚是，由于包装制卡和会员卡制息品与其他不黑白制卡和会员卡制息品在产物特不背上活命肯定的不同，所针差的用户差产物品格请求活命不同，不绝差于古板印后不入产的印版，CTP并不克不及使包装的品格爆不收较不小的改善，更不确不天说，此项加入不克不及不败为排斥更多客户的不现款，基于这样一种思绪，许多包装制卡和会员卡制息企业到不幼久还操纵采办CTP的意向，有的甚至觉得C下P差包装制卡和会员卡制息企业是只不赔不赔的交往，最多也只是范畴必给而已。

In order to get out from the cockamamie work in road route design for designers, on the basis of studying the internal relations among local schemes, local scheme was decomposed to small unit logic schemes; the directed network was used to represent the topological connection; the united data structure of point-arc was used to express a network graph. Based on the shortest path theory, the combinatorial optimization algorithm that can search optimal logical schemes of some targets in the network graph intelligently and can form the whole scheme automatically was put forward.

为了使设计者从道路线路设计的繁重计算统计工作中解脱出来，在研究了局部方案间内在关联的基础上，提出了将局部方案分解为更小单位的逻辑方案，用有向网络图表示逻辑方案间的拓扑关系，采用节点－弧段联合数据结构来表示网络图；同时基于最短路径理论，提出了在网络图中智能化搜索综合指标最优的逻辑方案集，自动形成整体方案的组合优化算法。

"I like September best," explained Oscar G髍riz, the proprietor of Sa Rascassa, a five-room pension and restaurant on a minuscule cove called Aiguafreda — reachable by car, of course, but also by foot along a seaside path from the tiny white-washed village called Sa Tuna.

&我最爱九月了。&萨拉斯卡萨的老板奥斯卡·格瑞斯解释说，他拥有一个五间房的廉价旅馆，还有一个餐馆坐落在一个叫艾格法瑞达的小海湾上，当然，开车可以到达，沿着海边小径，从一个名叫萨图那，以白墙抢眼的小村庄步行也可到达。

Such is life for all small Greenskins. There's always something after them. Though the Gnoblars are often impromptu snacks, they are at least more fortunate than many other greenies in that their mates are very big indeed! It's a symbiotic relationship.

战锤世纪，战锤online，战锤中文，游戏论坛，帐号申请，新闻截图，游戏评测，视频，客户端下载这就是所有小绿皮们的生活，没有最差只有更差，虽然葛鲁巴经常被当作即兴小点心，但是他们仍然比许多别的绿家伙好运，因为他们的同伙个子实在够大。

The formal potentials in cyclic voltammograms of these 3+ valence complexes are followed: Co〓-TPPS (-0.08V )＞Fe〓TPPS (-0.14V)＞Mn〓-TPPS (-0.23V). The electrochemical reaction of Mn〓-TPPS is reversible, and both of Co〓-TPPS and Fe〓-TPPS are quasi-reversible. The standard heterogeneous rate constants of Co〓-TPPS and Fe〓-TPPS were determined to be 1. 4×10〓cm/s and 1.4×10〓cm/s respectively. The rates of electrode reaction are as followed: Mn〓-TPPS＞Co〓-TPPS＞Fe〓-TPPS, e.i. Mn〓-TPPS is the most easily oxidized by the dissolved oxygen, and Fe〓-TPPS is oxidized slower than Co〓-TPPS. Ni〓-TPPS can not be oxidized. It is considered that oxygen plays an important role in the valence change of central metal atom and the rate of electron transfer in some metalloporphyrins.

三价金属卟啉络合物在循环伏安图上可得到三价到二价的还原和氧化响应，电极电位从大到小排列为：Co〓-TPPS(-0.08V)＞Fe〓-TPPS(-0.14V)＞Mn〓-TPPS(-0.23V)，电极反应可逆性也不相同，Mn〓-TPPS是可逆过程，Co〓-TPPS、Fe〓-TPPS是准可逆过程，实验测得Co〓-TPPS的标准电极反应速率常数ks＝1.4×10〓cm/s，Fe〓-TPPS的ks＝1.4×10〓cm/s，电极反应的速率从大到小为：Mn〓-TPPS＞Co〓-TPPS＞Fe〓-TPPS，即Mn〓-TPPS最容易被溶解氧所氧化，Fe〓-TPPS被氧化的速度最慢，Ni〓-TMPyP不能被氧化，因此我们认为溶解氧对金属卟啉中心离子的价态和电子转移速率起着重要作用。
