电容保护器跳闸信号保持与复归的方法分析

电容器是电路连接中必不可少的装置,其主要功能是储藏电荷以维持电路的正常运行。电容保护器对电容器在执行操控指令时出现的异常情况进行有效保护,从而避免故障给线路及装置元件造成损坏。电容保护器在检测到异常信号之后可及时发出警告信息,避免电路连接受到各种损坏。鉴于此,文章主要分析了电容保护器跳闸信号的保持与复归方法,从而提出了有效的处理方案。

Changing laundry habits in Norway

Maintenance is often the most energy‐demanding stage during clothes' life cycle. Therefore, a shift towards more sustainable washing habits has great potential to reduce the consumption of energy, water and detergent. This paper discusses the change in laundering practices during the past 10 years in Norway and suggests strategies to help consumers change their laundry habits to more sustainable ones. Quantitative information of consumers' experiences, habits and opinions concerning clothing maintenance was collected through three surveys in Norway in 2002, 2010 and 2011. The 2010 study was supplemented with qualitative in‐depth interviews of a strategic sample of households. The average washing temperature has decreased slightly during the studied time periods. Some products' washing frequencies remained the same, whereas other products such as jeans were used a few more days before washing. The cotton programme is the most used washing programme, but short programmes are gaining popularity. The laundry sorting processes vary greatly and are influenced by several factors such as washing temperature, colours, fibre type and use area. For some consumers, the use of several different sorting categories made it more difficult to collect a sufficient amount of clothing to fill the machine. They were also afraid that overfilling the machine would result in clothes that were not clean enough or had detergent residues. Detergent dosing practices are far from optimal. In 2010, although the majority of respondents only used eye measure and did not know the water hardness of their area, they still tried to vary detergent dosage based on the amount of laundry and the level of soiling. Different design for sustainable behaviour strategies could be used within detergent dosage systems, care labelling, machine programme selection (such as suggesting lower temperature and eco‐programme), machine filling grade indicators, storage systems for slightly used clothing and textile material choice.     

关于乡村道路硬化后养护与管理的几点思考

乡村道路条数多、里程长、涉及面广、投资少、配套不完善、基础设施差,乡村道路与人民群众的利益息息相关、密不可分。特别是在党中央、国务院提出建设社会主义新农村的宏伟目标后,各级党委、政府高度重视乡村道路的硬化工作。
