麻石文丘里洗涤吸收器在APV尾气处理上的应用

介绍了ＡＰＶ喷雾干燥尾气的性质，原尾气系统存在的问题，改造中采取的措施、原理、流程和取得的效果。实践证明，用“麻石文丘里一次降温、洗涤—ＸＰ型塔板二次洗涤—旋流除雾器除雾”的改造方案，取代原“换热器降温—喷淋塔洗涤—折流脱水器脱水”的流程，取得了良好的降温、洗气和除雾效果，且工程费用低。     

四川呷村多金属矿床地球化学特征及成因

呷村矿床是一个特大型的含金、稀土富银多金属矿床.成矿地质特征与日本黑矿相似.矿床形成于中低温、较低压的环境.成矿溶液为中等盐度、低密度水热体系.铅等成矿元素主要来自岛弧火山岩,硫和锶来自深部岩浆和海水,成矿水介质以大气降水为主,为典型海底火山热液—喷气沉积成因的块状硫化物矿床.     

厦门西港和九龙江口浮游植物生化组成及其环境因子效应

厦门西港和九龙江口浮游植物碳水化合物与光强、盐度和叶绿素ａ均显著正相关，蛋白质与光强有负相关关系，脂类受光强的影响较小，蛋白质与碳水化合物之比与氮磷比显正相关。１０月该海域浮游植物叶绿素ａ与生化组分含量都比４月高，与１０月海水温度和海面辐照度较高有关     

灌溉水库群优化调度的AD模型

随着国民经济的不断发展,工农业用水日益增长,但可供利用的水资源有限,使得供水与需水矛盾加剧。因此,对流域内或流域间的水库进行联合调度和管理,将有限的水资源统筹安排、挖掘潜力、充分发挥现有工程的效益、提高供水的保证程度即对水库实施优化调度很有现实意义。本文应用系统分析方法,建立了灌溉水库群优化调度的聚合分解(AD)模型,以保证在系统整体效益最优条件下得出各库的最佳运行策略,从而使水库的运行管理建立在科学的基础之上。

Detection of Escherichia coli in wastewater based on enzyme immunoassay

This research describes a fast detection method on the basis of enzyme-linked immunosorbent assay (ELISA) for Escherichia coli in drainage of wastewater treatment plants. Optimized conditions such as the reaction format (sandwich or direct), the concentrations of diluted horseradish peroxidase (HRP)-E. coli conjugate, and anti-HPR antibody and pretreatment of E. coli were studied. Those results showed that the linear range of detection for E. coli was 10 cfu/mL-6 × 10⁴ cfu/mL. Compared with conventional methods, it is a convenient and sensitive detection method with low cost.

比较研究：德国的企业补充养老保障制度

在养老保障制度中,越来越多的国家采取“三支柱：模式,即法定养老保险为第一支柱,企业补充保障（在我国称为企业年金）为第二支柱,而个人补充保障则为第三支柱.这三大支柱在整个养老保障制度中相互补充,为人们的老年生活构筑一张坚实的保障网络.     

Volcano-related materials in concretes: a comprehensive review

Massive volcano-related materials (VRMs) erupted from volcanoes bring the impacts to natural environment and humanity health worldwide, which include generally volcanic ash (VA), volcanic pumice (VP), volcanic tuff (VT), etc. Considering the pozzolanic activities and mechanical characters of these materials, civil engineers propose to use them in low carbon/cement and environment-friendly concrete industries as supplementary cementitious materials (SCMs) or artificial/natural aggregates. The utilization of VRMs in concretes has attracted increasing and pressing attentions from research community. Through a literature review, this paper presents comprehensively the properties of VRMs and VRM concretes (VRMCs), including the physical and chemical properties of raw VRMs and VRMCs, and the fresh, microstructural and mechanical properties of VRMCs. Besides, considering environmental impacts and the development of long-term properties, the durability and stability properties of VRMCs also are summarized in this paper. The former focuses on the resistance properties of VRMCs when subjected to aggressive environmental impacts such as chloride, sulfate, seawater, and freezing–thawing. The latter mainly includes the fatigue, creep, heat-insulating, and expansion properties of VRMCs. This study will be helpful to promote the sustainability in concrete industries, protect natural environment, and reduce the impacts of volcano disaster. Based on this review, some main conclusions are discussed and important recommendations regarding future research on the application of VRMs in concrete industries are provided.
