Three new asymmetrical diarylethenes containing an azaindole moiety and a variable heteroaryl ring have been synthesized. Their properties, such as photochromism, fatigue resistance, thermal stability, acidichromism, and fluorescence, were systematically investigated to elucidate the effects of aromatic stabilization energies （ASE） of the heteroaryl moieties. The results indicated that thermal stability decreased with the increment of the aromatic stabilization energies of the variable heteroaryl rings in the order of thiazyl〈thienyl〈pyrrolyl. Moreover, the dual switching behaviors of these azaindole-containing diarylethenes were also studied by the stimulation of acid/base and light. Addition of trifluoroacetie acid to the solutions of these diarylethenes resulted in obvious hypochromie shifts, and their N-protonated forms also exhibited favorable photochromism.

In this paper, coordinating technique for the multi-layer model predictive control（MPC） of complex water network is proposed. A multi-layer topology structure resulting from a functional decomposition of water network is briefly presented. Inside each layer, a MPC based controller is used. Between the related two layers, a multi-layer coordinating mechanism is provided to generate control strategies which consider objectives and time scales of both layers. Optimal Path Method（OPM） is used to estimate aggregated water price for the whole layer. The case study is the Catalunya Regional Water Network. Simulation results based on an aggregate model of this network are provided.

集体经营性建设用地入市旨在推动集体和国有建设用地平等入市,促进农民和集体公平分享土地增值收益,确保城市和乡村共享改革发展成果。为实现上述价值目标,需要理顺集体经营性建设用地入市规划主体,协调统一村庄规划的制定和实施,赋予农民和集体实质性参与规划权利,明确集体经营性建设用地的规划条件;拓展集体经营性建设用地入市规划用途,科学辨析规划用途的规范意旨,慎重对待成片开发的社会效果,前瞻预判入市用途的制度功能;填补集体建设用地异地入市的规范空白,以满足异地入市的试点实践和法政策需求,确认集体申请改变土地用途的规划权利,避免利用增减挂钩政策突破建设用地规模、危及耕地保护安全;增量集体经营性建设用地入市符合宪法秩序,存在法律空间,应重新重视并在立法中明确乡村建设用地指标的配置规则。
