摘　　要：介绍了一种新型氨分解率测量装置。其原理是根据氨气极易溶于水的特点 ,利用可编程控制器PLC、压力传感器、电磁阀等元件实现了氨分解率的自动测量。该装置与计算机联接 。An instrument of measuring the ammonia dissociation rate was introduced.Based on the principle that ammonia can easily dissolve into the water,this instrument achieves the auto-measuring of ammonia dissociation rate by applying the components such as the PLC,pressure sensor, magnetic valve,etc.Combining with the computer,this instrument can also realize the autocontrol of the nitrogen potential in the nitriding process.
