Abstract ：
建筑业是国民经济发展支柱，其产业链长、碳排放总量大，有着巨大的减排潜力。零碳建筑研究的兴起，是实现“双碳”目标的必经之路。本文在调研国外发达国家与权威组织的基础上，对比分析了各国零碳建筑标准发展历程、共性及差异性，结合我国低/零碳建筑发展现状，提出部分建议，旨在推动我国建筑领域“双碳”目标。

Abstract ：
为更好评估管网失效风险等级，以中国西北某城市排水管网为研究对象，基于组合权重和风险矩阵法的排水管网失效风险评估方法，对研究对象主要失效风险可能性和失效后果指标进行分析。失效可能性指标中，管龄、管理制度、管材和土壤性质对失效风险影响很大；失效后果指标中，环境影响、社会影响、经济影响失效后果影响很大；该方法所确定的失效风险级别与实际检测结果基本符合，评价结果较准确，能有效识别管段的失效风险。本研究成果可为管网运营维护工作提供决策指导，降低城市内涝风险。

Abstract ：
Cross-linked α-methylstyrene maleic anhydride copolymer microspheres (PAMSM) were prepared by self-stable precipitation polymerization with α-methylstyrene and maleic anhydride as copolymer monomers and divinylbenzene as crosslinking agent. Firstly, mono-6-p-toluenesulfonyl- βcyclodextrin (mono-6-OTs-β-CD) was obtained by the monosulfonylation of β-cyclodextrin (β-CD) with p-toluenesulfonyl chloride, and then 1,2-propylenediamine-β-cyclodextrin (PDM-β-CD) was achieved by the ammoniating of mono-6-OTs-β-CD with excess 1,2-propylenediamine. The microspheres of β-CDPDM-PAMSM were prepared though immobilizing PDM- β -CD to the PAMSM by ringing-open amidation reaction of PDM-β-CD with the primary amines and PAMSM with the anhydride groups. The composition, surface morphology, particle size and distribution of the β-CD-PDM-PAMSM were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and elemental analysis. The results showed that the β-CD-PDM-PAMSM maintained good sphericity and the average particle size was 1.08µm. The immobilization yield of β-CD on PAMSM was high, and the grafting rate of β-CD was 53.1% calculated by the elemental analysis. Then, the adsorption properties for methylene blue solution (MB) of PAMSM, β-CD-PDM-PAMSM, hydrolyzed PAMSM (H-PAMSM) and hydrolyzed β-CDPDM-PAMSM (H-β-CD-PDM-PAMSM) were investigated. Research suggested that the adsorption capacity of PAMSM for MB was 25.3mg/g, and the adsorption capacity of β-CD-PDM-PAMSM for MB was 615.8% higher than that of PAMSM. The adsorption capacity of H-β-CD-PDM-PAMSM and H-PAMSM for MB was 1043.5% and 860.8% higher than that of PAMSM, respectively. © 2023 Chemical Industry Press. All rights reserved.

Abstract ：
以α-甲基苯乙烯和马来酸酐为共聚物单体,二乙烯基苯为交联剂,通过自稳定沉淀聚合制备交联α-甲基苯乙烯马来酸酐共聚物微球(PAMSM);用对甲苯磺酰氯对β-环糊精(β-CD)进行单磺酰化得到单-6-对甲苯磺酰基-β-环糊精(mono-6-OTs-β-CD),其与过量的1,2-丙二氨反应制备得到1,2-丙二胺基-β-环糊精(PDM-β-CD);通过PDM-β-CD的伯氨与PAMSM的酸酐开环酰胺化反应,将β-CD固载在PAMSM上制备微球β-CD-PDM-PAMSM.采用傅里叶红外光谱(FTIR)、扫描电子显微镜(SEM)、元素分析对β-CD-PDM-PAMSM的结构、表面形貌和组成进行表征.结果表明,β-CD-PDM-PAMSM具有良好的球形度,平均粒径在1.08μm;β-CD固载率高,通过元素分析计算得β-CD固载率为53.1％.将PAMSM、β-CD-PDM-PAMSM、水解PAMSM(H-PAMSM)和水解β-CD-PDM-PAMSM(H-β-CD-PDM-PAMSM)作为吸附剂,研究其对亚甲基蓝溶液(MB)的吸附性能.研究表明,PAMSM对MB的吸附能力为25.3mg/g,β-CD-PDM-PAMSM对MB的吸附能力比PAMSM提高了615.8％,水解后的H-β-CD-PDM-PAMSM和H-PAMSM对MB的吸附能力较PAMSM分别提高了1043.5％和860.8％.
