基于2008—2021年全国30个省市区的面板数据,运用中介效应检验模型,实证研究城镇化是否会通过产业集聚影响农业碳排放,并进一步通过面板门槛模型研究城镇化对农业碳排放的作用是否会受产业集聚程度的影响。结果表明:城镇化对农业碳排放有显著的正向影响,城镇化水平越高,越会加剧农业碳排放;产业集聚在城镇化对农业碳排放的影响中具有重要的中介作用,城镇化会促进产业集聚进而增加农业碳排放;城镇化对农业碳排放的影响,受产业集聚的单一门槛效应的影响,当产业集聚程度跨越门槛值后,城镇化对农业碳排放的正向促进作用成倍减少。

为充分利用智能电表采集的细粒负荷数据并提高区域商业建筑负荷预测的精确度,提出一种基于用电行为模式的区域商业建筑负荷预测方法。首先,基于均值方差归一化方法对采集到的负荷数据进行标准化处理,通过肘方法确定聚类数目后进行k-Shape聚类,实现区域商业建筑负荷不同用电行为模式的提取;其次,针对大规模商业建筑负荷预测问题,考虑区域内大量商业建筑负荷预测时耗费大量内存资源却难以实现较准确预测问题,提出一种改进的Informer模型,该模型通过聚类算法识别具有相似用电行为模式的商业建筑,并充分考虑智能电表采集的异常负荷数据对模型训练结果的影响,能够良好的解决大规模商业建筑负荷预测精度不高问题;最后,采用加利福尼亚州商业建筑负荷进行实验,实验结果表明所提方法能够有效提高区域商业建筑负荷预测精度。

Light emitting diode (LED-UV)/chlorine disinfection can replace UV/chlorine disinfection in wastewater treatment plants and water supply plants. Halonitromethanes (HNMs) are a class of novel nitrogenous disinfection by-products, which are characterized by higher cytotoxicity and genotoxicity than regulated disinfection by-products. Herein, the impact factors and pathways of HNMs formation from aspartic acid (ASP) were investigated during LED-UV_(265)/chlorine disinfection. The results showed that three types of chlorinated-HNMs (Cl-HNMs) were found during LED-UV265/chlorine disinfection, and their concentrations increased first and then declined as the reaction progressed. Cl-HNMs yields increased with increasing LED-UV_(265) intensity, free chlorine dosage, and ASP concentration, which declined with increasing pH (6.0–8.0). Meantime, the important impact of the coexisting ions contained in water matrices on HNMs formation from ASP was observed during LED-UV_(265)/chlorine disinfection. It was found that copper ions (Cu^(2+)) promoted Cl-HNMs formation. Furthermore, when bromide (Br–) appeared during LED-UV265/chlorine disinfection, nine types of HNMs were detected simultaneously. Moreover, Br– not only converted Cl-HNMs toward brominated (chlorinated)-HNMs and brominated-HNMs but also showed a marked effect on HNMs concentrations and species. Subsequently, the possible pathways of HNMs formation from ASP were proposed during LED-UV_(265)/chlorine disinfection. At last, it was proved that the formation trends of HNMs obtained in the real waters were similar to those in simulated waters. This work elaborated on the influence factors and pathways of HNMs formation, which is conducive to controlling the HNMs produced during LED-UV_(265)/chlorine disinfection.

In this paper, the design of plasma swirler is presented in detail. The experiments were carried out to verify the feasibility of using plasma swirler to control diffusion flame. The plasma swirler consists of multiple electrodes with staggered arrangement on both sides of combustor’s expansion section. The plasma swirler can enhance combustion stability through ionizing the air to produce active free radical and promoting the swirling air. In the experiments, the flame response to the plasma swirler was examined with OH distribution by planar laser induced fluorescence (PLIF). The experimental results showed that the flame reaction zone was broadened with the increase of the plasma exciting, and this demonstrated that the plasma swirler could be used to control diffusion flame. The design of plasma swirler is feasible.

生长和繁殖之间的权衡是克隆植物适应性策略的重要组成部分。根茎型沙生植物通过权衡策略应对风沙过程(埋沙和风蚀)对它们在流动沙丘上的定居尤为重要。尽管根茎型物种对风沙过程的响应已经有了部分研究,但这些克隆物种如何通过生长和繁殖中的潜在权衡关系来应对风沙过程仍不清楚。在本研究中,我们采用了野外调查和生物量建模的手段,评估了芦苇(Phragmites communis)在沙埋和风蚀条件下,营养生长和生殖生长以及分株数量和大小之间的权衡关系。研究结果表明,沙埋促进了种子生物量和生殖努力(RE)的增加;风蚀减少了RE,但对种子生物量没有显著影响。沙埋增加了分株的生物量,而风蚀增加了分株种群密度并加速了分株的成熟。这些研究表明,根茎型沙地植物通过调整其生长策略来应对风沙过程,即在沙埋条件下,增加生殖生长和分株大小,而在风蚀条件下,增加营养生长和分株数量。
