摘　　要：通过改良双通道强度型光纤传感器参考端的参考方式,把参考光纤置于与待测物具有相同或相近折射率温度系数的液体中,从而消除外界环境的不稳定性和多变性.通过食盐、蔗糖和冰糖的溶解速率对比实验,以及胶水和蜡烛的凝固实时监测实验,结果表明,这种传感方式能够很好地对物质的溶解和凝固过程进行实时在线监测.Through improving improved it s the reference method of inserting the reference point into the liquid which has the same or similar thermal refractive index coefficients as the under checked liquid,it can more accurately eliminat the instability of external environment.After the experiments of dissolvings of salt,sucrose,suger candy and the coagulating of waterglue and candle,the results show that the sensor can be competent for the on-line real-time monitoring of the dissoluting and coagulating process.
