摘要

为了解决入渗数据人工观测过程中的劳动量过大和读数误差问题

设计了利用压差传感器与数据采集器联合运行

自动搜集入渗数据的自记录盘式负压入渗仪。对盘式负压入渗仪原理与各部件组成

压差传感器与储水管的联合运行机制

以及数据采集器采用的数学处理过程进行了研究。通过自由入渗、室内土柱入渗和田间入渗实验3种方式逐步校验了该仪器读数的准确性和应用的可靠性。

Abstract

In order to solve the problem of large amount of labor and the error of readings during the manual measurement

a simple automated disc infiltrometer is designed.It links a differential transducer and a data logger and gets infiltration data automatically.The principle and components of the disc infiltrometer

the combination mechanism of the differential transducer with the water storage pipe

and mathematical process used in the data logger are studied.The accuracy of data readings and reliability of application of the device is verified by the tests of free infiltration

soil column infiltration and field infiltration.
