The characteristic of moire fringe is that the image is white alternate with black  the angle of the stripes is uniform  the width of the stripes is uniform  the terminators of the stripes aren't clear. A fast method that can figure out the width and angle of the moire fringe precisely is put forward in this paper. It calculates the angle the stripes firstly. According to the principle of the minimum mean squared error (MMSE)  the closer a series of data is  the smaller the value of the MMSE will be. The method is described as follows: It takes the image's center as the origin  180 beelines pass through the origin with the same angle interval. it calculates the value of the minimum mean squared error of the 180 beelines and find out the least one among those  then the angle of the moire fringe comes out primarily. In order to improving the calculating precision of moire fringe  60 equal angles are divided in the neighborhood of the angle  then a precise angle of moire fringe is calculated according to the principle of the MMSE. After getting out the angle of the moire fringe  we begin to calculate the width of moire fringe. A line vertical with the moire fringe is drawn  and we can get the width of the moire fringe by the vertical line. In order to get over the influence of the noise  an effective area with the shape of diamond is selected in the image. The data of area is accumulated and projected according to the direction of moire fringe  and a sine curve come out. The width of moire fringe can be obtained by getting the position of the first wave crest  the position of the last wave crest and the number of wave crest. Experiments prove that the precision of the method put forward in this paper is enhanced in comparison with the traditional frequency method  the precision of width calculation achieves to 99.6% according to the evaluation indicators of width detection error. The computing speed is boosted largely compared with traditional method  and it can achieve with 15 ms  that satisfying the demand of real time. 2011 SPIE.   New relativistic mean field interactions for light nuclei 期刊论文  OAI收割 HIGH ENERGY PHYSICS AND NUCLEAR PHYSICS-CHINESE EDITION, 2006, 卷号: 30, 页码: 68-70 作者:  Sun, Bao-Yuan;  Meng, Jie   |  收藏  |  浏览/下载：17/0  |  提交时间：2018/05/31 relativistic mean field theory  pairing correlation  microscopic center-of-mass correction  light nuclei  effective interaction  binding energy  shell structure   Scenarios of major terrestrial ecosystems in China 会议论文  OAI收割 Conference on Ecological Models as Decision Tools in the 21st Century, Quebec, CANADA, AUG 22-24, 2004 作者:  Yue, Tian Xiang;  Fan, Ze Meng;  Liu, Ji Yuan;  Wei, Bo Xin 收藏  |  浏览/下载：20/0  |  提交时间：2016/01/12 Holdridge Life Zones  scenarios  mean-center shift  spatial pattern  HadCM2  HadCM3   Scenarios of major terrestrial ecosystems in China 期刊论文  OAI收割 ECOLOGICAL MODELLING, 2006, 卷号: 199, 期号: 3, 页码: 363-376 作者:  Yue, Tian Xiang;  Fan, Ze Meng;  Liu, Ji Yuan;  Wei, Bo Xin 收藏  |  浏览/下载：15/0  |  提交时间：2015/10/13 Holdridge Life Zones  scenarios  mean-center shift  spatial pattern  HadCM2  HadCM3
