矿产资源型城市在我国能源资源保障和经济健康发展中具有重要地位,其具有固体废物产生量巨大、利用程度总体不高、环境污染问题突出等特点,矿产资源型城市如何建设“无废城市”是我国“无废城市”建设工作中的重要议题,也是美丽中国建设中的关键环节.本文从矿产资源城市的分布分类、固体废物特点等方面分析了其基本特征,指出矿产资源型城市开展“无废城市”建设工作面临管理体制机制融合不足、法律法规和标准体系不健全、固废“三化”技术不足、固废资源属性和污染属性辩证对待不清晰等方面的难点问题;简要总结了我国“无废城市”建设工作开展以来取得的主要成效和实现矿产资源型城市“无废化”目标的典型经验.指出在推进矿产资源型城市“无废城市”建设过程中,一方面要借鉴先进成熟经验,做好顶层设计,重视法律法规和标准体系的建设;另一方面要强化技术研发创新,立足城市实际重点解决难点问题,并注重多源固体废物协同利用处置体系建设.

As an important traffic mode, urban rail transit is constantly developing toward improvement in service capacity and quality. When an urban rail transit system is evaluated in terms of its service capacity, the train departure capacity is an important index that can objectively reflect the service level of an urban rail transit facility. In light of the existing cellular automaton models, this paper proposes a suitable cellular automaton model to analyze the train departure capacity of urban rail transit under different variable factors and conditions. The established model can demonstrate the train operating processes by implementing the proposed sound rules, including the rules of train departure at the origin and intermediate stations, and the velocity and position updating rules. The properties of train traffic are analyzed via numerical experiments. The numerical results show that the departure capacity is negatively affected by the train departure control manner. In addition, （i） the real-time signal control can offer a higher train service frequency; （ii） the departure capacity gradually rises with the decrease in the line design speed to a limited extent; （iii） the departure capacity decreases with extension in the train length; （iv） the number of departed trains decreases as the train stop time increases; （v） the departure capacity is not affected by the section length. However, the longer the length, the worse the service quality of the urban rail transit line. The experiments show that the proposed cellular automaton model can be used to analyze the train service capacity of an urban rail transit system by performing quantitative analysis under various considered factors, conditions, and management modes.

PLGA, m PEG diblock copolymer was synthesized by bulk ring-opening polymerization method. The double emulsion solvent evaporation method was used to prepare bovine serum albumin（BSA）-loaded microspheres. Optical microscopy was used to observe the whole microsphere fabrication process. It is confirmed that the proportion of inner aqueous phase is one of the most critical factors that determines the morphology of microspheres. Double emulsion droplets which have appropriate amount of inner aqueous phase can form closed and dense microspheres, while, too much inner aqueous phase will cause a collapse of the double emulsion droplets, resulting in a loss of drug. The proportion of inner aqueous phase was varied to prepare microspheres of different morphology. The results show that with increasing the amount of inner aqueous phase, a higher percent of broken microspheres and lower encapsulation efficiency appeared, and also, a more severe initial burst release and faster release rate.

关键词： Microspheres PLGA-m PEG Morphology Encapsulation efficiency Release profile
