基于PO和DGT技术，研制了一种新型的复合膜传感器，用于沉积物和水体中溶解氧动态和不稳定磷通量的亚毫米级二维联合测量。该混合膜由支撑两个光敏层的透明聚酯膜组成，即，覆盖DO感测层（DSL）的P结合层（PBL）。一个强大的，简单的测量策略的基础上参考RGB和彩色计算机成像密度（CID）的方法。溶解氧的传感特性显示出相当的均匀性（RSD < 5%）和快速响应（
A novel sensor assembled by a hybrid film was developed for 2D combined measurements of DO dynamic and labile P flux in sediment and water at sub-millimeter resolution based on PO and DGT techniques. The hybrid film is comprised of a transparent polyester membrane supporting two ultrathin sensing layers, i.e., a P binding layer (PBL) overlying a DO sensing layer (DSL). A robust, straightforward measuring strategy based on the referenced RGB and coloration-computer imaging densitometry (CID) methods was developed. Sensing properties for DO show a considerable homogeneity (RSD < 5%) and rapid response (
