一般含硫较高的硫化金属矿山废石和尾矿属第Ⅱ类一般性固体废物,需要根据处置场的工程地质和水文地质条件确定其防渗结构;但废石及尾矿浸出毒性监测结果表明为第Ⅰ类一般性固体废物,实际设计时我国的废石场和尾矿库也均按第Ⅰ类一般性固体废物进行设计,不采取任何防渗措施,根据笔者长期的跟踪和调查,废石场和尾矿库工程设计未采取防渗措施,造成部分硫化金属矿山地下水和土壤受到不同程度的污染,鉴于目前毒性浸出鉴别标准的局限性,建议硫化金属矿山工程设计和环境影响评价时,应类比同类型矿山废石场淋溶水和尾矿库外排废水水质监测值,确定其废石场和尾矿库是否要采取防渗措施.  相似文献

This paper highlights technology development for space exploration. It draws on the proceedings of Space 88, Engineering, Construction, and Operations in Space, which includes 125 papers and 1,349 pages providing in‐depth discussions of space policy, extraterrestrial basing, space stations, orbiting structures, and areas of special interest. In the space station and orbiting structures (orbital facilities) section, papers discuss the engineering, construction, and operations of orbiting space systems. Papers in the extraterrestrial basing section deal with the engineering, construction, and operations challenges faced in development of bases and operations on extraterrestrial bodies. The special interest (interacting disciplines) section provides a discussion of challenges facing us in meeting needs for space power, life support, human factors, astronomy, education, and management. The purpose of this volume on engineering, construction, and operations of facilities and bases in space is to encourage and stimulate the development of the required technologies. The concluding section of this paper focuses on space policy and a view toward the future.  相似文献

Both hardiness and religiousness share spirituality, in the sense of searching for meaning in one's life, and have been shown to have a buffering effect on stresses that maintains and enhances performance, morale, and health. This study investigates how hardiness and religiousness compare in their relationship to depression, anger, and the coping and social support mechanisms whereby they may have these relationships. Participants were military and governmental personnel who completed accepted measures of hardiness, religiousness, and other variables on a volunteer basis. Correlational and multiple regression analyses showed that, by comparison with religiousness, hardiness has the larger and more comprehensive negative relationship with depression and anger, and positive relationship with coping and social support. The conceptual and empirical implications of these findings are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Compared to storm water runoff, urban roadway snow exposed to traffic and winter maintenance practices has a much greater capacity to accumulate and retrain heavy metals and other anthropogenic constituents. Heavy metals once released in the environment are not degraded and partition between the dissolved and particulate-bound fractions. Residence time, solid loadings, alkalinity, hardness, and pH influence partitioning. Accretion and partitioning of Pb, Cu, Cd, Zn, Al, Ca, Na, Mg, and Fe from a series of urban highway sites in Cincinnati, Ohio, are compared to temporal accretion trends at a control site removed from the highway environment. Results from partitioning analysis indicate that Pb, Cu, Cd, Zn, Al, Mg, and Fe were all highly particulate bound, while Na and Ca were mainly dissolved for all highway sites. Partition coefficients for most heavy metals in snowmelt ranged from 103 to 106?L/kg. Concentrations for Pb, Cu, Cd, Zn, and cyanide were orders of magnitude higher than at the control site and exceeded storm water runoff concentrations by one to two orders of magnitude. For residuals analyses, the specific surface area generally increased with decreasing particle size while the predominance of total surface area (SA) was associated with the medium to coarser size fractions. Heavy metal mass trends followed similar general trends to that of the SA. Characterization of accretion and partitioning of these metals is a necessary first step toward development of management and treatment strategies designed to address urban snow pollution.  相似文献

This article explores the concept of self-relatedness, integrating ideas drawn from attachment theory, developmental studies, object relations, and interpersonal neurobiology with a multiplicity model of self. I suggest that because self-regulation begins as a dyadic interpersonal process between child and attachment figure, the mind renders such regulatory abilities across the life span via an analogous, intra-relational dyad. This “internal attachment system,” comprising states representing our subjective experience and states reflecting on and appraising that experience coordinates its activity in ways that best regulate the individual's affects, thoughts, perceptions, and behavior. Chronic trauma and neglect create patterns of intrapsychic relatedness that compromise connection, receptivity, adaptive engagement, and harmony among elements of the self system, thereby disrupting the mind's development toward greater coherence and complexity (Siegel, 2007). This article will also discuss the clinical application of intra-relational principles with pervasively maltreated people using a method called Intra-relational (I-R) Accelerated Experiential Dynamic Psychotherapy (Lamagna & Gleiser, 2007). Applying Accelerated Experiential Dynamic Psychotherapy's use of dyadic affect regulation, the tracking of emergent somatic experience, and the processing positive effects associated with transformation to inner work with various internal parts of the self, I-R seeks to foster attunement and receptivity among previously dissociated parts of the individual. Creating intrapsychic safety provides an opening through which defensively excluded memories and associated emotions, thoughts, and impulses can be processed and integrated and increasingly coherent and complex forms of self-organization can be achieved.

A review of ceramic matrix composites is presented as related to their type, use, and fabrication. Ceramic composites have the potential for high fracture toughness, resistance to catastrophic failure, high strength, low density, low thermal expansion, and high temperature capability and oxidation resistance. For continued development, there are a number of key technical needs including new refractory matrices, new stable fibers, and inert coatings for flbers, as well as affordable techniques which produce the desired composite properties and accomplish complex shape capability. A better materials understanding is necessary, including fiber∕matrix interaction, and mechanics∕structure∕property relationships. Finally, technologies for transition to practice are required, including advanced materials characterization, component design methodology, large scale fabrication, attachment techniques, and nondestructive evaluation. While these composites are in the research and development stage, they offer the structural engineer excellent rigidity, high strength‐to‐weight ratio, high temperature capability and a noncatastrophic failure mode. Potential applications include turbine and internal combustion engines, aerospace structures, and high temperature leading edges and skins. A current application is the use of SiC whisker reinforced Al2O3 matrix composites as cutting tools. Significantly increased cutting speeds, improved interrupted cut performance and increased tool life are found.  相似文献
