根系吸水模型 参数优化 混合遗传算法
2009/9/11
构建了遗传算法与Levenberg-Marquardt算法相结合的混合遗传算法，用于求解根系吸水模型参数。分别进行数值试验和棉花根系吸水试验对混合遗传算法求解精度进行验证。数值试验表明，采用混合遗传算法优化求解根系吸水模型参数的优化值具有较高的精度，含水率资料的时间步长和空间步长对根系吸水模型参数的优化精度有较大影响，在实际中时间步长可取值5～10d，空间步长取值5～10cm。对室内棉花根系吸水进...
A Bernoulli Inverse Method for Determining the Ocean Circulation
Bernoulli Inverse Method Ocean Circulation
2009/1/13
A new inverse method for finding the large-scale ocean circulation is described. Unlike most previous methods it uses no horizontal gradient information, and is designed for widely spaced data. The me...
