2001年,中国移动手机用户已超过一亿,再加上中国联通的手机用户,目前,中国的手机用户已是一个庞大的群体.我们现在所使用手机的款式五花八门,同样和手机相配套的电池也多种多样,目前主要有氢镍电池、锂离子电池和聚合物锂离子电池三种,电池变得越来越小、越来越轻,但是其最重要的一项性能指标--容量却没有发生质的变化.所谓电池的容量就是指在一定的放电条件下可以从电池中获得的电量,常用Ah或mAh来表示,对于手机电池来说其现实表现就是待机时间或持续通话时间,现在最好的聚合物锂离子电池的持续通话时间也只能维持在几个小时. 相似文献

目前市场上的手机电池主要有两种类型,一种为氢镍电池,一种为锂电池.前者由于体积大、质量大,再加上其还存在一定的记忆效应,所以它虽然目前还占有一定的市场份额,但是市场份额正在逐步萎缩.现在市场上较多的手机电池是锂电池,一般人们去购买电池时看到是锂电池就认为都是一样的,其实这是不对的,实际上锂电池也分为两种,一种就是大家常说的锂离子电池,另一种则是聚合物锂离子电池.一些不法商人往往利用人们对这两种电池的不了解,采取偷梁换柱的方法,用锂离子电池来代替聚合物锂离子电池. 相似文献

The present paper investigates the potential benefits of a strong safety culture (SC). Specifically, we build on the organizational support theory to explore the direct and indirect effects of SC on firm performance. Partial least squares method is used to analyze the data collected from a survey among 251 Canadian plants. The results show that SC is associated with several performance indicators all linked to sustainable development (i.e., environmental, financial, and safety performance). Importantly, our findings also suggest that the relationships between SC and environmental/safety performance are mediated by the actual level of implemented environmental/safety practices within plants. We conclude the paper by highlighting the study’s limitations and contributions as well as theoretical and managerial implications. 相似文献

The World Trade Organization (WTO) is a product of the General Agreement on Tariffs and Trade (GATT). The WTO was created in the last round of negotiations (Uruguay Round, 1986‐94) to provide a stronger set of institutions to administer the various agreements negotiated under the GATT framework. Because the WTO is more powerful than its predecessors, critics claim that it poses a threat to national sovereignty. Concerns about the ability of nations to set their own environmental and health and safety agendas have figured prominently in these critiques. In addition, critics suggest that the WTO prioritises trade objectives at the expense of environmental and health and safety objectives. The article explores the extent to which the WTO has been able to reconcile trade, environmental and health and safety objectives by analysing its rulings on these matters. Overall, this analysis suggests that the WTO dispute resolution process has balanced all three sets of objectives. However, it is important to note the small number of disputes to date; only 21of the 175 disputes before the WTO involve environmental and health and safety matters. Further, the WTO has issued decisions in only six of these cases. 相似文献

Injury is a leading cause of morbidity and mortality in the United Arab Emirates (UAE). The UAE is a rapidly developing country with fast economic growth, demographical and environmental changes that are associated with new hazards emerging at a similar pace. The UAE as a federal entity has federal and local systems responsible for safety policy, regulations and enforcement. To set priorities for safety promotion and injury prevention, it is necessary to have data on the most frequent external causes of injury and the main individual, equipment and environmental risk factors that contribute to injury. However good quality data for injury prevention are scarce. The aim of this paper is to describe the scale of injury as a public health problem in the UAE, and the development of safety policies, regulations and promotion efforts with special emphasis on traffic, occupational and child safety. 相似文献
