他不说则罢，一说反使我心中好胜之气油然而生。我爽朗地一笑，道： “ 那就试一下吧！ ” 立即开始进入七级宇宙共振态。 裁判点了点头，道： “ 那好，我也想开开眼界，我还从来没有看到谁能把这张弓拉开半个弧的呢。 ” 我现在确信，即使是蓝族最强壮的勇士也只能将这张弓拉出个轻微弧度而已，弓本身的重量就相当可怕，手上没有五百公斤以上的力量，根本不可能将它平举起来，至于拉开它，就不知是否超越了人类体能的极限？ 我从箭壶中拽出一支最粗的箭，搭在弓弦上，双腿一前一后弓步站稳，缓缓举起了手中的银白色弓。像在平和中注入了一股清风，周围的气氛开始扰动。 蓝姑娘和众人们加油声不断传来，我感觉到自己先天真气从下丹田的阳光处扩展到全身，全身的血液似乎沸腾了。 三百公斤的重量对处于七级宇宙共振态的我来说实际并不算什么，我很轻松地将手中的银白色弓举到与肩平行的位置，手臂没有一丝的颤抖。右手搭在弓弦上，缓缓后拉。 然而一拉上弓弦，我才明白为什么裁判刚才会告诉我那些话了。这把银白色弓弦的韧性和硬度是如此之强，令人匪夷所思，以致我甚至怀疑它是否是来自我们这个星球上的材料。 在七级宇宙共振态中运用先天真气的情况下，以我的力量竟然也只能拉成半弧。 但即使是这样，裁判和周围的其他选手都吃惊的看着我，甚至都已经忘记了自己正在比赛之中。 时间就象凝固一样，周围的荧光为之变色。 我鼓起勇气，急忙进入九级宇宙共振态，先天真气骤然迸发出紫色的光芒，随着紫色光芒的闪耀，银白色的硬弓一点一点被拉开了。 然而 ， 我发现这弓越拉到后来就越费劲，尽管我体内的先天真气已经完全调动起来，全身的肌肉都澎湃着强大的力量 ， 但是当银白色的硬弓被拉开 80% 左右的时候，九级宇宙共振态先天真气却已经无法再将弓弦扩张哪怕 1 厘米。 But his saying instead to cause my heart trying, I give a hearty laugh, saying : " I just t r y !" Then, I s tart to enter seven th level of univers al resonating status immediately. The referee nod s to say : "That is good, I also want to open mind, I ha ve not seen anyone can pull open this bow as half arc." I believe now, e ven if the blue race strongest brave warriors only can pull out a radian of this bow . The bow itself weight is quite fearful, in the hand if there is no 500 kilogram above strength, you are simply impossible to rise it evenly, as for pulls open it, I don't know whether beyond human physical limits? I entrain one the most thick arrow from the arrow pot, put it on the bowstring, the both legs stand as lunge , and raise the hand silver-white color bow slowly. As in the order poured into the hot blast, the surrounding atmosphere beg i n to warm. The blue girl and supporters sounds transmit unceasingly; I fe el my naive Qi expanded to my whole body from the below Dantian sunshine , my body blood seethes with excitement. The 3 00 kilograms weights comparing with the seventh level of universal resonating condition is not big actually, I am relaxed to lift the silver white bow t o the shoulder parallel position, an arm not shivering. My r ight hand puts on the bowstring and opens pulling slowly. However as soon as I d raw the bowstring, I only then underst an d why the referee could tell me a moment ago. The silver white bow toughness and hardness is so strong, that is fantastic, I even doubt whether it is from the planet materials. Under utiliz ing first naive Qi in seven th level of univers al resonating condition, unexpectedly I only can pull half arc by mine strength . B ut even if is so , the referee and the periphery other contestants all are startled look ing at me, even all already ha ve forgotten their own competing. Time is like solidification, surrounding the fluorescence for discoloration. I have the courage, hurriedly enter the ninth level of univers al resonating condition the naive Qi suddenly burst s out the violet ray, along with the violet ray sparkling; the silver white color hard bow is pulled open. I find that , this bow more pull ing afterwards more us ing energy, my naive Qi already completely transferred in my vivo, the whole body muscle is rushing the formidable strength. But, when the silver white hard bow is pulled to about 80% , the nin th level of univers al resonating condition naive Qi already i s unable to expand anymore bowstring.

获取ARCGIS中polygon的中心点坐标（基于ArcGIS Desktop 9.3） 2009-05-17 11:08 大家好 我是GIS理想 这次我们研究下怎样获取ARCGIS中polygon的中心点坐标 其实这个问题很早就遇到了 也没来得及总结 群里也有友友们在询问 这里集中解决一下啦 不妥之处 还请大家批评指正~~~ 下面是arcgis help里的讲解（这段是别人整的 貌似有点问题 我先贴下 后面我提供了解决办法）： Adding the x,y coordinates of the centroid of a polygon layer to a new field 1. Optionally, start an edit session in ArcMap. Calculating a field is faster outside of an edit session, but you won't be able to undo the calculation. 2. Open the attribute table of the layer of the layer you want to edit. 3. Right-click the field heading for the X field (if there is no X field you can add a new field by clicking the options button and selecting the new field option). 4. Click Calculate Values. 5. Check Advanced. 6. Type the following VBA statement in the first text box. Dim dblX As DoubleDim pArea As IAreaSet pArea = dblX = pArea.Centroid.X 7. Type the variable dblX in the text box directly under the X field name. 8. Click OK. You can repeat the same process for updating a field with the Y coordinates for the centroid point of each polygon in the layer. ? The property X returns a field type of double. For best results, your X field should also be a double field type. 下面我简要的翻译下 不敢保证百分百正确哈 呵呵 其实这些小问题 大家也都能看得懂。。。。。。 在计算面的中心点坐标的时候 用的是字段计算器（当然了还有其他方法） 第一步 添加X Y字段 注意在对面图层添加字段的时候 图层不能是可编辑状态 也就是说Editor下面不要选择开始编辑状态即可 第二步 选择编辑 右键图层打开属性表 第三步 右键X字段表头 选择字段计算器 第四步 选中Advanced 第五步 编写VBA代码 ： Dim dblX As Double Dim pArea As IArea set pArea = dblX = pArea.Centroid.y 然后在下面一栏里直接填上“dblX” 点击OK 即可 为了取得更好的效果 建议在字段的声明类型与vba类型一致 下面我介绍另外一个方法 不用写VBA代码了 因为属性表里操作已经为大家准备好了 就是修改上面第三步的操作 不要选择字段计算器 选择计算几何要素（calculate Geometry） 然后在Property下拉列表框里选择相应的属性即可 显然这里默认的计算有面积 周长 中心坐标XY 其他操作就与上面的一样了 很明显这样的话不用书写VBA代码了 稍微简单一点 不过本人还是推荐大家用VBA 毕竟这样有助与 对AE的理解 对搞开发有帮助的 ~~~吼吼 对了 大家可以直接在HELP里查找 这里面对VBA代码说的也很详细的 我这里也贴出来一点供大家参考 不翻译了哈 很简单的 How to use Visual Basic code to calculate fields based on area, length, perimeter, etc. You can use Visual Basic code in the Advanced box in the Field Calculator dialog to calculate fields using geometric measurements. Although the easiest way to perform these calculations is to use the Calculate Geometry dialog described above, there may be situations where you want to use Visual Basic code to perform these calculations in the Field Calculator instead. These examples show how to do this. 1. These code examples return a value of type 'double', so use them to calculate either an existing field of type 'double' or a new field of type 'double' you've added to the table. 2. Check Advanced. You'll see two empty text entry boxes. 3. Enter one of these four line code examples into the topmost box, the one labeled 'Pre-Logic VBA Script Code'. Tip: you can select the code in this help topic, right-click and choose Copy, and then paste it into the box. To calculate area: Dim Output as double Dim pArea as Iarea Set pArea = Output = pArea.area To calculate length or perimeter (depending on whether the features are lines or polygons): Dim Output as double Dim pCurve as ICurve Set pCurve = Output = pCurve.Length To add the x coordinate of points: Dim Output As Double Dim pPoint As IPoint Set pPoint = Output = pPoint.X To add the x coordinate of polygon centroids: Dim Output As Double Dim pArea As IArea Set pArea = Output = pArea.Centroid.X 4. Type the variable Output into the second text box. Do not enclose it in quotes or brackets. 5. Click OK The units of the calculated values will be the units that your features are stored in, not the map units or display units of the data frame you are currently working with. So if your data is stored in feet, the calculated values will be in feet. If you want the calculated data to be in different units than the data's units, you could either add a conversion into the calculation expression, or (more simply) project your data into a coordinate system that uses the units you want the values to be in, and then perform the calculatio 最后我贴出来一些DESKTOP里常用的VBA代码吧 没有一一验证: （下面代码转载自集思学院） 特点: 1推荐给不会使用AO的朋友 2可以保存为CAL文件以备下次方便使用 使用方法 1打开属性表,选择计算的字段,右点选择Calculate Values； 2.选择“是”，进入Field Calculator； 2选择Advance选项； 3 在Pre-Logic VBA Script Code编辑框中输入VBA代码； 4在下面编辑框中输入赋值部分. 1--点坐标X VBA部分: Dim pGeo As IGeometry Set pGeo = Dim pPoint As IPoint Set pPoint = pGeo 赋值部分: pPoint.X 2--点坐标Y VBA部分: 同上 赋值部分: pPoint.Y 坐标值为文件存储的固有值,和是否使用On the Fly坐标表示无关。返回当前显示的坐标值参看8,9 3--多边形周长 VBA部分: Dim pGeo As IGeometry Set pGeo = Dim pPolygon As IPolygon Set pPolygon = pGeo 赋值部分: pPolygon.Length 4--多边形面积 VBA部分: Dim pGeo As IGeometry Set pGeo = Dim pPolygon As IPolygon Set pPolygon = pGeo Dim pArea As IArea Set pArea = pPolygon 赋值部分: pArea.Area 5--多边形重心X VBA部分: Dim pGeo As IGeometry Set pGeo = Dim pPolygon As IPolygon Set pPolygon = pGeo Dim pArea As IArea Set pArea = pPolygon Dim pPoint As IPoint Set pPoint = pArea.Centroid 赋值部分: pPoint.X 6--多边形重心Y VBA部分: 同上 赋值部分: pPoint.Y 7--Polyline长度 VBA部分: Dim pGeo As IGeometry Set pGeo = Dim pPolyline As IPolyline Set pPolyline = pGeo Dim pCurve As IPolycurve Set pCurve = pPolyline 赋值部分: pCurve.Length 8--表示点坐标X VBA部分: Dim pDoc As IMxDocument Set pDoc = ThisDocument Dim pSpRef As ISpatialReference Set pSpRef = pDoc.FocusMap.SpatialReference Dim pClone As IClone Set pClone = Dim pGeo As IGeometry Set pGeo = pClone.Clone Dim pPoint as IPoint Set pPoint = pGeo pGeo.Project pSpRef 赋值部分: pPoint.X 9--表示点坐标Y VBA部分: 同上 赋值部分: pPoint.Y

Offshore staff SYDNEY, Australia – China’s State Oceanic Administration has approved the Environmental Impact Assessment (EIA) for the Beibu Gulf project in the South China Sea. This allows work to start on development of the WZ 6-12 and WZ 12-8 West oil fields . However, the partners await final approval for sanction of the project by the National Development and Reform Commission. Fabrication activities are under way and offshore pipeline installation should start in March. Platform installation should be completed before mid-year, at which point a campaign of four exploration/appraisal wells will begin, to be followed by development drilling. CNOOC anticipates first oil from the Beibu Gulf project by end-2012, building to peak production during 2013. The partners are: CNOOC (51%); Roc Oil (19.60%); Horizon Oil (14.70%); Petsec Petroleum (12.25%); and Oil Australia (2.45%). 2/27/2012 http://www.offshore-mag.com/articles/2012/02/china-sea-oil-field-development.html
Have you beenfrustrated that you took the photo with wrong focus and what you meant to see is not very clear in the picture? Now you won't have that problem anymore, since the Lytro Inc have created a new kind of camera, light-field camera, you can capture the scene first, and then refocus it! It's a total new experience and has been called the first revolution of cameras since 1800s! A light-field camera, also called aplenoptic camera, is a camera that used a microlens array to capture4D light field(color, intensity and vector direction of the rays of light) information about a scene. Such light field information can be used to improve the solution of computer graphics and vision-related problems . The light field is a core concept in imaging science, representing fundamentally more powerful data than in regular photographs . The applications of light fields conclude all uses of computational imaging in art, science, engineering, and medicine. For instance, Light Field Rendering , Synthetic Aperture Photography and 3D Display . Perhaps in the future, it will play a important role in Remote Sensing Photogrammetry !

In mathematics a Vector field is a construction in vector calculus which associated a vector to every point in a subset of Euclidean space. Vector fields are often used in pysics to model, for example, the speed and direction of a moving fluid thoughout space, or the strength and direction of some force, such as the magnitic or gravitational force, as it changes from point to point.
EIGEN-1S is a satellite-only gravity field model including 88 days of CHAMP data. The model is a combination of GRIM5-1S normal equation system More can be found on the section 1.3 webpages Lageos-1,-2, Starlette derived constraints on zonals additional Lageos-1,-2, Starlette and Stella laser tracking data (year 2000) CHAMP GPS satellite-to-satellite tracking data: 88days within the periods 2000, July 30 - Aug. 10, and Sept. 24 - Dec. 31 (accelerometry used for surface force reduction) Please note: although higher degree/order terms are solved in EIGEN-1S, the solution has got full power only up to about degree/order 35, which is typical for a satellite-only solution. Higher degree/order terms are solvable applying stochastic a priori information according to a degree variance model (regularization of the normal equation system). The EIGEN-1S data set contains fully normalized spherical harmonic coefficients complete to degree/order 100 with higher degree terms up to maximum degree 119 for CHAMP sensitive and resonant orders permanent tide is not included in C(2,0) C(0,0) and degree 1 terms are not solved DOT-terms (C(2,0) to C(4,0)) represent drifts per year, epoch for corresponding static terms: 1997.0 standard deviations are given along with the coefficients. The standard deviations were posteriori calibrated applying a degree dependent calibration factor (cf. header of EIGEN-1S data set) The EIGEN-1S correlation matrix of the spherical harmonic coefficients is available as a CHAMP OG Level 4 product through the CHAMP Information System and Data Centre (ISDC) the formats are described on the CHAMP web pages (op.gfz-potsdam.de/champ) under 'Online Available Documents' in the document 'CHAMP gravity field solution data formats'. from:http://www.gfz-potsdam.de/pb1/op/champ/results/index_RESULTS.html
EIGEN-CHAMP03S is a CHAMP-only gravity field model derived from CHAMP GPS satellite-to-satellite and accelerometer data out of the period October 2000 through June 2003. EIGEN-CHAMP03S is the final version of the preliminary model EIGEN-3p and results from a homogeneous reprocessing of all normal equations including the improved parametrization of the accelerometer calibration parameters. Normal equation regularisation starts at degree 60. from:http://www.gfz-potsdam.de/pb1/op/champ/results/index_RESULTS.html
