中性分子 meaning in Chinese

neutral molecule

This thesis is mainly centered on the following two research aspects : 1 ) synthesizing six kinds of porphyrins containing different functional groups and applying them to analytical chemistry respectively . based on the principle of energy transfer , a series of optical chemical sensors have been developed and applied to food examination , environment monitoring by detecting inorganic ions , inorganic neutral molecules and toxic organic neutral molecules . 2 ) improving the electric circuit of pqc sensors , then designing and assembling pqc sensor array , which has been used to examine the mix gases
基于以上目标，本论文主要完成了两方面的研究工作： 1 )合成并表征了6种不同的卟啉化合物，并把它们分别应用到分析化学方面，以能量转移原理研制了一系列光化学传感器，检测了重要的无机离子、无机中性分子和有机中性分子，应用领域涉及了食品检验、环境监测等方面； 2 )改进了压电传感器电路，采用优化电路设计并组装了压电传感器阵列，同时进行了多组分的检测。
