Dear editor,rnIn recent decades,researchers have started seeking for sub-stitutes for silicon based circuits to perform computation in other fields,including synthetic biology and molecular com-puting[1,2].rnPrevious researches indicate that many circuit behaviors can be mapped to chemical reactions[3,4].Also,because chemical reactions satisfy mass action kinetics[5],the be-haviors of chemical reactions are constrained by ordinary dif-ferential equations (ODEs) thus ensuring the predictability and programmability of chemical reaction networks (CRNs).Ref.[6]proved that researchers can utilize toehold mediated DNA displacement reactions[7]as substrates to implement arbitrary CRNs consisting of formal chemical reactions (re-actions involving only formal species,i.e.,symbols that do not correspond to any real world material) with less than or equal to two reactants in real world.With theoretical programmability and real-world implementability,CRNs be-come a powerful programming language in the implementa-tion of different types of circuits.By designing CRNs,the functions of certain circuit components can be reliably im-plemented with chemical reactions.

本文以中国五大城市群的90座城市14年的工业绿色发展为研究对象,通过构建工业绿色发展能力评价体系,使用熵权—TOPSIS方法测算城市群及相关城市的工业绿色发展水平,并进一步使用泰尔指数法和基尼系数法测算城市群之间、城市群内部城市之间的差异.研究发现:中国五大城市群的工业绿色发展能力自东南沿海至内陆呈阶梯状递减,不同梯度城市群间的差异并没有缩小迹象;平均水平高的城市群内部城市之间的差异性更明显,发达城市的虹吸效应通过抑制要素流动阻碍了城市群中其他城市工业绿色能力的提高,且此现象并未出现明显缩小趋势.
