conic function

With the request of synchronization data for decomposing these parameters,an instrument for simultaneous measurement of soil water content and cone index has been developed.

为了满足参数解耦对数据同步性的要求,研制了一种可同步测量土壤剖面水分与圆锥指数的智能化测量装置。

Cone index penetrometer is a special apparatus widely used for assessing soil compaction in agriculture.

圆锥指数仪是农业上用于测量土壤压实度的专用设备。

In particular, this system is able to characterize soil cone index and water content profiles at the depths of 0~40 cm.

该系统既能在0～40cm深度之间提供土壤圆锥指数分布与含水率分布剖面,而且还可运用信号处理中的相关理论分析双变量传感器输出信号间的相关特性。

In this paper,we give a method to establish the relation function on a space trus field,by using the cone function method.
