Remote Sensing Measure of Crop Area Based on Spatial Sampling

基于空间抽样的农作物面积遥感测量

There are many difficulties in how to check random data form,how to establish sampling interval and so on in system sampling and random sampling.

审计抽样是一项技术性很强的方法，我国许多民间审计人员，在操作应用之时感到比较困难，有许多障碍，如系统抽样、随机抽样时如何查随机数表、如何确定抽样间隔等等。

SARDS not only measures every parameter at a sampling process accurately, but also dynamicly adjusts the sampling interval with the change of the network traffic.

以单点被动测量为背景,提出一种新的抽样方法———自适应随机双抽样,该方法既能兼顾各个参数在统计精度上的平衡,又能随网络流量变化,动态调整抽样间隔。

Control limits and sampling interval are two essential parameters of control chart.

控制界限和抽样间隔是控制图的两个基本参数。
