Global Trend of Low-carbon Economy and China's Responses

Based on the analysis on the global economic crisis,climate change crisis and their mutual underlying reasons,the authors believe that low-carbon economy has become an inevitable choice to break through the dual crises,coordinate the economic development,and protect the global climate.The global trend of low-carbon economy finds expression in Green Recovery currently,while,in a long run,it will give rise to a new pattern of world competition in politics,economy,technology,trade and finance.The impact of the...     

公众态度和机构监督对大气污染的影响

虽然以往对于环境库兹涅兹曲线（EKC）的研究中考虑了正式制度因素如政府机构监督，但是较少考虑非正式制度因素.本文重点检验两种制度情境的影响，微观层面的环境态度形成的非正式制度以及宏观层面的环保机构监督形成的正式制度对大气污染排放量的影响.基于CGSS2010-2013和2015年的数据库，从中提取出体现环境态度的问题，将其赋值指标化后，作为制度情境纳入环境方程.经过公开数据的收集，得到我国26个省份2010-2014年5年的面板数据.通过固定效应和随机效应模型，发现机构监督与人均GDP的交互项对氮氧化物、烟（粉）尘、二氧化硫排放都有影响，但是公众态度与人均GDP的交互项只对烟（粉）尘排放有影响，从而对不同制度情境下的环境库兹涅兹曲线进行了探索.     

Production of the monoclonal antibody against tylosin for immunoassay of macrolide antibiotics in milk

The objective of the present study was to develop an immunoassay for multi-determination of the residues of four macrolide antibiotics in milk. Tylosin was derivatized with 6-aminohexanoic acid to synthesize a hapten that was used to produce the monoclonal antibody. The obtained monoclonal antibody simultaneously recognized tylosin, acetylisovaleryltylosin, tilmicosin and desmycosin with crossreactivities of 100%, 91%, 49% and 76%, respectively. Then an indirect competitive immunoassay was developed to determine the four analytes in milk simultaneously. The limits of detection for the four analytes were in the range of 5.5–11.7 ng/mL depending on the compound. The recoveries of the four analytes from fortified blank milk were in the range of 78%–96% with coefficients of variation lower than 11.4%. The developed immunoassay could be used as a practical tool for rapid screening the residues of the four anlytes in milk.

一次能源消费结构变化对我国单位GDP能耗影响效应研究

基于1980—2004年能源统计数据，首先和用通径分析法测算了一次能源消费结构、技术、管理医素与单位GDP能耗强度的关系。定量分析了各一次能源消费构成比例（煤，石油，天然气，水电等消耗比例）对单位GDP能耗的直接、闻接和总影响程度；结果表明：技术水平及管理水平等不可测因素对我国单位GDP能耗起决定作用，石油消耗比例为单位GDP能耗变化的主要限制性因素，故在煤的消费比例下降幅度较小的情况下，要想达到节能降耗的目的，必须首先重视技术的进步及管理水平的提高，同时提高石油的使用比例，尤其要重视水电的发展。然后利用通径分析结果消除了多重共线性的影响，建立了单位GDP能耗同一次能源消费结构及其它相关因素间的多元回归模型，分析了能源消费结构的调整和优化对节能降耗的影响途径及影响效应。     

Local Area Quotas for Industrial Emissions along Reaches of the Pearl River in Guangdong

There is an obvious departure from the regional equilibrium of developments between the upper and lower reaches of the Pearl River in Guangdong, which resulted in ＂the effects of contra-geography-grads development＂. It is mainly because the upriver mountainous areas have been deeply stuck in industrialization delay and marginalization plights, so that nearly 40 million local people have conceived a dream to get rid of ＂the vicious circle of poverty＂ by speeding up industrial development. But the problem is that such industrialization efforts on a large scale in mountainous areas are encountering the bottleneck of environmental capacity that strictly limits industrial emissions along the upper reaches of any water system. As a solution, an institutional arrangement called ＂the Local Area Quotas for Industrial Emissions along the Pearl River＂ is put forward supposed to give corresponding compensation to the rights of industrial development yielded by some areas with lower environmental capacity through the distribution and trading of IDQs.

Measurement of air exchange rates in different indoor environments using continuous CO2 sensors

A new air exchange rate (AER) monitoring method using continuous CO₂ sensors was developed and validated through both laboratory experiments and field studies. Controlled laboratory simulation tests were conducted in a 1-m³ environmental chamber at different AERs (0.1-10.0 hr^-1). AERs were determined using the decay method based on box model assumptions. Field tests were conducted in classrooms, dormitories, meeting rooms and apartments during 2-5 weekdays using CO₂ sensors coupled with data loggers. Indoor temperature, relative humidity (RH), and CO₂ concentrations were continuously monitored while outdoor parameters combined with on-site climate conditions were recorded. Statistical results indicated that good laboratory performance was achieved: duplicate precision was within 10%, and the measured AERs were 90%-120% of the real AERs. Average AERs were 1.22, 1.37, 1.10, 1.91 and 0.73 hr^-1 in dormitories, air-conditioned classrooms, classrooms with an air circulation cooling system, reading rooms, and meeting rooms, respectively. In an elderly particulate matter exposure study, all the homes had AER values ranging from 0.29 to 3.46 hr??1 in fall, and 0.12 to 1.39 hr^-1 in winter with a median AER of 1.15.
