- The authors have used a low-cost ROV of observation type for underice surveying of the Nen-Jiang Cross-river oil pipe line in the Da Qing oil field. The operation method, process and the safety measures for severe cold areas are presented. The fruitful tries and experience may be useful to ROV operators in severe cold areas. 相似文献

美国、英国、日本、意大利、巴西等国先后对本国欠发达地区进行了开发建设。它们以城镇化为动力、大力发展城镇工业,已经取得许多成功经验,也有着深刻的教训。中国西部大开发可从国外开发欠发达地区的经验教训中受到启迪,以城镇化为增长点带动区域经济的全面发展,重视生态环境的保护和建设,加强以交通运输为重点的城镇基础设施建设,探索出西部地区城镇工业独特的发展道路,实现经济、社会和环境的可持续发展。 相似文献

This paper is a partial discussion of a four-year study that investigated the vulnerability of the people living in the Cairns region to the tropical cyclone hazard. The longitudinal case study, focussing on the Cairns Northern Beaches area, was unique in that it included a social and societal `pre-cyclone impact' evaluation of various resident communities within the region, and then two consecutive `post-cyclone impact' studies. The primary research method supported an inductive qualitative approach to the collection and analysis of survey data. Some quantitative methods were invoked to support qualitative research findings. Survey data was collected in five separate questionnaire-based social surveys that were administered between 1996 and 2000. During the study, residents experiencedthe direct impact of two land-falling tropical cyclones. In addition to this, targeted andfocussed tropical cyclone awareness education was made increasingly available withinthe community. The social and demographic attributes that influence the individual'sperception of risk and contribute to our understanding of community vulnerability were examined and evaluated. Changes in the residents' attitudes, cyclone preparednessbehaviours and willingness to respond to cyclone warnings were monitored and measured. Analysis of early survey data indicated that community residents generally had some knowledge of cyclones but a limited understanding of cyclone processes and very little direct personal experience of the cyclone hazard. Individually and collectively, residents frequently demonstrated a biased perception of the risks associated with cyclones. The resident community was shown to be fragmented, with limited support being available to individual households. Initially, residents were found to be poorly prepared for cyclones and unlikely to respond to warnings appropriately. It appeared that, in the event of a land-falling tropical cyclone impacting the area, the community was highly vulnerable to unnecessary loss of property, livelihood and – in extreme circumstances – life. By 2000, Cairns community residents were somewhat better informed about cyclones and certainly more experienced. This paper provides some insight into how cyclone experience and education may synergisticly have contributed to a change in risk perceptions and a reduction in the vulnerability of Cairns residents to the tropical cyclone and storm surge hazards. 相似文献

The economic restructuring since German unification has produced gender-differentiated patterns in the rural workplace. Most studies of East German labour market changes have illustrated the nature of such patterns in quantitative terms whilst neglecting their impact on everyday life. The relationship between the significance of work for women's quality of life and self-identification, and women's withdrawal from the public has, however, remained under-explored. Based on data obtained through correspondence and in-depth interviews in Mecklenburg-Westpommerania, this paper aims to address this relationship by discussing women's work-related experiences before and since unification. 相似文献
