讨论了原位连续测定土壤—天然水化学性质的实际意义。设计了一套原位连续检测技术测定土壤—天然水某些化学性质的自动测量系统,该系统由复合探头、用于传输测量讯号的长屏蔽电缆、测量仪器、接口电路、应用软件和打印机等组成。这种检测系统可以用来自动测定土壤和天然水的pH、电导、温度、Eh和pX(某些离子的浓度),测量距离为50—100米,具有良好的稳定性和抗静电干扰能力,已在中国科学院红壤生态实验站获得成功的应用,并列出了一组实验结果。
The practical significance of in-situ continuous determination of soil-natural water chemistry was discussed. An automatic in-situ measurement system for the determination of some chemical properties of soil-natural water was designed. The system consisted of a composite probe, long-shielded cables for measuring signals, measuring instruments, interface circuits, application software and printers composition. This detection system can be used to automatically determine the pH, conductance, temperature, Eh and pX (concentration of some ions) of soil and natural water at a measuring distance of 50-100 meters, with good stability and antistatic interference ability, Has been successfully applied to the Chinese Academy of Sciences red soil ecological experiment station, and lists a set of experimental results.
