ABAQUS计算多相材料的前处理器 voronoi

魏凤英的现代气候统计诊断与预测技术的fortran源代码，里边包括气候变化趋势分析的程序：线性倾向估计、滑动平均及一些趋势检验和函数；气候突变检测：滑动t检验、Cramer s法、Yamamoto法、Mann-Kendall法、Pettitt法Lepage法；气候序列周期的提取方法：功率谱、最大熵谱、交叉谱、多维最大熵、奇异谱分析、小波分析；以及EOF、主成分等等，总之熟悉这本书的同学，应该知道这本书的“强大”是做数理统计分析、及气象等必备的工具书啊，而且其程序，尤为宝贵！特此与大家分享！！！(WeiFengYing modern climate statistical diagnosis and prediction technology of FORTRAN source code, the inside including climate change trend analysis program: linear tend to estimate, moving average, accumulative anomaly, five, seven and nine point two times smooth cubic spline function and some trend test and functions Climate mutation detection: sliding t test, Cramer s method, Yamamoto method, Mann- Kendall method, Pettitt method Lepage method Climate sequence cycle extraction methods: power spectrum, the maximum entropy spectrum, cross spectrum, multidimensional maximum entropy, singular spectrum analysis and wavelet analysis And EOF, principal component, etc., in short familiar with this book classmate, should know the book "strong" is doing mathematical statistical analysis, and weather required reference ah, and its program, particularly precious! I share with you!!!!!! )
