The real reflectors of various antennas used in radar and satellite communication earth stations are distorted when affected by different loads. A new divided-fitting method is proposed which is quite different from the traditional best-fit paraboloid method. 针对工程中雷达天线、卫星通讯地面站天线等的实际反射面在载荷作用下发生变形,基于变形反射面实际形状,提出了一种与传统最佳吻合抛物面法不同的新的分块拟合方法。
The best-fit regression equation was set up for seedlings height, stem diameter and root growth of Pinus nigra through the method of stepwise regression. 苗高生长量与侧根鲜重关系最密切,地径生长量受根系鲜重影响最大。应用逐步回归法建立了苗高、地径生长量与根系生长关系的最优回归方程。
