In this paper a flowrate measurement method in pipe directly using light fibres with some fluorescent tracer is proposed. This method will work better than traditional tracers measurement such as using radioactive or salt tracers. It is shown that the flowrate signals are sensitive and intensive also if the injected tracer volume is very small and if the tracer concentration is very lew (<10ppm) ico. It is also show that the calibration factor K is constant within a certain flowrate range. An estimation of uncertainty of flowrate measurement is given, which shows that the measuring accuracy can be within ±2%.  相似文献

3 Brief explanation of the programs The No.3 program demostrates a sorting process, its sorting key word is character string. It needs to create a string file before it runs. The length of each string is ramdom, length maximum is 20, a string consists of 26 lower letters a..z. The No.2 program and No.1 program demostrate repectively a sorting process too, their sorting key words are integer or  相似文献

A.S.拜厄特的五部短篇小说集所包含的故事在主题、象征、结构等方面看似千差万别,但通过对主题及写作特色进行分析对比却可发现它们有着各自内在的联系,融合了拜厄特短篇小说的主要特征,即对女性生存状况的关注与反思,超自然的奇幻性特征,以及叙事中强烈的自省和试验因素,极大丰富了后现代主义短篇小说的内涵。  相似文献

清洗产业是世界各国第三产业——服务业的一个重要组成部分。它与社会经济,人民的生活乃至国家的整体形象息息相关。同时它涉及面广,是社会经济生活中每一个领域,每一个人都不可缺少的,都离不开的。中国清洗产业领域和世界发达国家相比,无论从清洗设备、清洗技术、清洗剂产品到清洗工作人员的素质,都存在较大的差距,这给清洗产业提供了巨大的商机,也给我们今天百万下岗工人再就业提供了一个广阔而又实际可行的市场。丹麦IDUNA/S化学公司认为,政府在关心大环境环保工作的同时,应该关心清洗产业经济的发展,只有动员全社会,才能真正地做好环保工作。这是中国可持续发展必不可缺的重要组成部分。  相似文献

Rape in today’s civil armed conflicts is particularly widespread and brutal, constituting what I refer to as extreme war rape, in which perpetrators intentionally injure and psychologically torture their victims. Using prior research as the data source, this article examines war rape in ongoing or recently-ended armed conflicts in 27 countries. Findings indicate that extreme war rape is ubiquitous and that across countries, there are similarities in its perpetration as well as in the contextual conditions that facilitate it. Based upon data that also show some variations in war rape prevalence and in the prominence of certain features, e.g., most common perpetrators or rape sites, I introduce four patterns of war rape, along with the distribution of conditions that differentiate them from one another.

The sharp increase in Dutch mothers’ labour market participation in recent decades has led to remarkable heterogeneous working patterns. This variation makes the Netherlands an interesting case with which to explore how mothers differ in their ‘narratives of choice’ and (early adult and present) attitudes towards work, gender and motherhood. This was conducted through 39 semi-structured interviews with mothers living in Amsterdam, The Netherlands. The study builds further on the scientific work on relationships between attitudes and personal preferences on the one hand, and employment behaviour on the other (e.g. Hakim, in Br J Sociol 54(3):339–345, 2003; Hakim, in Ashgate Publishing Limited, Hants, 2003; Halrynjo and Lyng, in Br J Sociol 60(2):321–343, 2009; Hoffnung, in Sex Roles 50(9–10):711–723, 2004; Sanders and Beekes, in Wolters-Noordhoff, Groningen, 1993; Thompson, in J Sci Study Relig, 30(4):381–394, 1991). Most of these studies are based on large surveys which lack the details of behavioural steps, preferences and attitudes that mothers themselves underline as relevant while describing their employment decisions. This qualitative study reveals a typology of Dutch mothers, based on the variety of their narratives of choice and considerations regarding the ideal gender division of labour, work and motherhood. The study also reveals a ‘narrative of acceptance’ among all interviewees regarding their spouses’ contribution to the unpaid work, accompanied by a disappearance of gender concerns.  相似文献

While voluminous research exists on managerial successions and the decline of female head coaches, limited research has evaluated the impact of the coach’s gender on a team’s performance. Therefore, this study focused on gendered coaching successions to determine if the gender of the head coach influenced the team’s performance when controlling extraneous variables (e.g., revenues, expenses, and team statistics). Utilizing the theoretical foundations of relational demography (Tsui et al. in Productivity and interpersonal relations in work teams characterized by diversity, American Psychological Association, Washington, DC, pp 97–130, 1995) , similar-attraction paradigm (Byrne in The attraction paradigm. Academic Press, New York, 1971) and social identity theory of leadership (SITL; Hogg in Pers Social Psychol Rev 5:184–200, 2001), we hypothesized coaching successions to similar demographic leader-member dyad relationships would positively impact team performance. Data from the National Collegiate Athletic Association and Equity in Athletic Data Analysis websites were collected on all Division I women’s basketball head coaching successions from 2003 to 2010. Coaching predecessors and successors were coded by gender, win-loss ratios, and performance statistics. Analysis of variance and repeated measures analysis of covariance were used to analyze the data. Results indicated demographic similarities in leader-member dyadic relationships do not advance team performance.  相似文献
