D-A的用法

All electronic multiplexing D-A converter system in industrial control computer

工业控制计算机中的全电子多路数-模转换系统

The serial synapses were observed, 1. The dendro-axo-dendritic synapse ( D-A-D1): The dendrite D synapses with the axon terminal A to form the dendro-axonic synapse ( D-A);

该核内的连续性突触有：1.树轴树突触（D-A-D1）：树突D内只含少量扁圆形突触小泡，与轴突A形成树-轴突触（D-A）；

For the synthesized D-A type molecules ( 4a-4F), the solvent effects, absorption spectroscopy, fluorescence spectroscopy, and cation effects test of Cu+ and Fe3+ were carried out. The corresponding fluorescence quantum yield was also calculated.

对合成的D-A结构化合物4a-4f分别进行了溶剂化效应、吸收光谱、荧光光谱及Cu2+、Fe3+阳离子效应的测试，并计算了荧光量子产率。
