The paper represents some results of comparative analysis of the methods used for processing and interpreting data of adiabatic calorimetry as well as applying it to practical situations. Specifically two approaches are compared – approximate method based on evaluation of simplified kinetics and a more comprehensive, simulation-based method that utilizes the evaluation of more detailed kinetic models.The analysis is focused on two important types of data processing – correction of experimental results on thermal inertia (phi-factor correction) and estimation of adiabatic time to maximum rate (TMR).The most widely cited method for phi-factor correction is considered and its improvement is proposed to enable more precise prediction of the adiabatic time scale. A procedure for phi-factor correction of pressure response is also proposed. The limitations of this enhanced Fisher's method are discussed by comparison with simulation-based method. All the illustrative materials are based on real examples.As an example of application, the simplified method will be used to predict TMR and its limitations will be discussed. 相似文献

This case study examines the coastal hazard adaptation strategies of a fishing community in a village in Kerala, India. It shows that formal adaptation strategies are highly techno‐centric, costly, and do not take into account the vulnerabilities of the fishing community. Instead, they have contributed to ecological, livelihood, and knowledge uncertainties. The adaptation strategies of the fishing community are a response to these uncertainties. However, they may not lead to the fishing community's recovery from its vulnerability contexts. This case study is primarily qualitative in nature. Data were collected through in‐depth interviews. Insights reveal that when actors with diverse values, interests, knowledge, and power evolve or design their respective adaptation strategies, the resulting interface often aggravates existing uncertainties associated with hazards. Furthermore, the study demonstrates that local discourses on coastal hazards are livelihood‐centric and socially constructed within the struggle of the fishing community to access resources and to acquire the right to development. 相似文献

伴随着经济的繁荣和人民物质生活质量的提高,餐饮业日益繁荣起来,再结合中国素来"民以食为天",传统饮食文化的特殊性及复杂性,导致烹饪过程复杂,同时也带来了各种各样的油烟污染问题。油烟已经成为继噪声、尾气、沙尘之后的又一大污染问题,并且成为百姓环保投诉的热点问题之一。《饮食业油烟排放标准》(GB18483-2001)是目前我国环保行业监测饮食业油烟的唯一标准方法,在实际工作中存在一定的局限性和不完备性,对现行标准进行修订势在必行。 相似文献

黄河下游泥沙灾害初步研究 总被引:8,自引:0,他引:8
基于黄河下游对泥沙运动与泥沙灾害发生的关系问题进行了分析。认为下游泥沙灾害类型主要包括洪水、河岸侵蚀、土地沙化、水涝和土地盐碱化, 并认为改造下游泥沙灾害环境应通过改变泥沙堆积分布入手。 相似文献

Central to the environmental and health hazards created by the expanding use of pesticides in developing countries is the
weakness of national regulatory agencies. This article reviews current international efforts aimed at supporting these institutions
and describes the contribution that an external “hazard auditor” might make in assessing the pesticide industry's adherence
to accepted standards of health and environmental protection. An independent evaluation of this kind may prove attractive
to all parties in the long-standing confrontation over the control of pesticide technology: the industry, public interest
groups, developing and developed countries, and international agencies. The article outlines one approach to operationalizing
the concept and examines initial responses to the proposal.
An earlier version of this paper was presented at the International Commission on Occupational Health/International Development
Research Centre Symposium on the Impact of Pesticide Use on Health in Developing Countries, 17–21 September 1990, Ottawa,
