摘要
提出了一种宽范围的ｐＨ传感技术。含有单一指示剂的ｐＨ识别器的检测范围一般都比较窄，而把二种有着不同检测区域的ｐＨ指示剂结合在一起形成的ｐＨ识别器可扩大其检测范围。人工神经网络能够识别非常复杂的模式，使用它可充分地利用ｐＨ识别器对光信号的调制信息。
A broad range pH sensing technology is described.The pH measuring range of the pH detector based on one pH indictor is often narrow.However,the pH detector based on two pH indictors with different pH measuring range may expend its pH measuring range.The artificial neural network is able to recognize very complex patterns.Processing the spectral information modulated by the pH detector by the artificial neural network,we can expend the measuring range of the pH detector.
