多指示剂复合pH敏感膜及其试验

Multi-indicator polymer pH sensing membrane and its test

采用多指示剂聚合构成 pH敏感膜 ,并用神经网络进行光谱处理 ,能有效扩大 pH的敏感范围 ,克服目前光纤化学 pH传感器量程小的缺陷 ,有助于该类传感器的实用化。

With multi-indicator based pH membrane and artificial neural network based spectroscopic treatment, the pH measurement range of the f iber-optic pH chemical sensor can be expanded greatly and it is therefore helpfu l to practical application.
