Sudoku is a game with incremental intelligence and is popularizing in many countries of Asia, Europe, and America. Its most common pattern is to fill the digits 1 through 9 into a square with 9 rows by 9 columns and subdivided 9 boxes, so that each
Two glasshouse studies were conducted to investigate the effect of interspecific complementary and competitive root interactions and rhizosphere effects on the concentration and uptake of Na, Cl and B, and N, P, K, Ca, Mg, Fe, Zn and Mn nutrition of

SWAT（Soil and Water Assessment Tool）是由美国农业部（USDA）的农业研究中心Jeff Arnold博士1994年开发的。模型开发的最初目的是为了预测在大流域复杂多变的土壤类型、土地利用方式和管理措施条件下，土地管理对水分、泥沙和化学物质的长期影响。SWAT模型采用日为时间连续计算。是一种基于GIS基础之上的分布式流域水文模型，近年来得到了快速的发展和应用，主要是利用遥感和地理信息系统提供的空间信息模拟多种不同的水文物理化学过程，如水量、水质、以及杀虫剂的输移与
