在当前社会经济高速运转的时代,电力资源的需求量与日俱增,电力安全问题也越来越受到人们的重视,这就对电气继电保护装置提出了更高的要求,加强继电保护装置的检修和运行维护,可以极大地提升电力系统的运行效率,并保证电力运行的安全性.但是,就目前情况来说,我国电气继电保护装置的运行过程中还是存在一些故障问题,需要采取措施加以改进.基于此,本文将围绕电气继电保护装置运行中的常见故障展开分析,然后对继电保护装置的检修方法以及运行维护措施进行了详细的探讨与研究,以供相关人员参考. 相似文献

Leader‐member exchange as a form of supportive leadership is expected to foster employee creativity. However, empirical evidence suggested this relationship is complex. This study attempts to address this complexity by proposing and testing a curvilinear mechanism, which attenuates the overall positive effect of LMX on creativity by transmitting a curvilinear indirect effect via vertical task conflict. Results drawn from a sample of 276 supervisor–subordinate dyads provided support for the hypothesized curvilinear indirect effect. Specifically, LMX was found to negatively influence employee creativity by suppressing vertical task conflict for subordinates in high‐quality LMX relationships, while the indirect effect was not significant for subordinates in low‐quality LMX relationships. 相似文献

随着我国基础设施建设深入践行"两山"生态环境理论,传统边坡防护不能满足新时代生态文明建设要求.文章介绍了植被对边坡的影响及岩质边坡生态护坡的常用方法,对岩质边坡的生态护坡特点进行了分析,对固土结构、基层材料、非生态装饰等关键问题进行了分析探讨,得到支护结构应与基层进行耦合分析、基层材料采用多孔材料有利于植被生长,基层填固应考虑与岩体嵌固附着作用,辅助装饰材料可达到较好的景观效果,具有一定工程社会意义,同时为类似生态护坡工程提供参考. 相似文献

中国的互联网金融经历了一个先创新发展后监管规制的过程,本文通过对网络借贷行业的实证研究,分析监管规则的出台实施对新型互联网融资市场有效性的影响。实证结果表明,网络借贷平台资金的银行存管、持有ICP证等强制性规定缓解了投资者、平台企业与借款人之间的信息不对称,对克服早期平台间通过竞相承诺高回报率来吸引投资者导致的“柠檬市场”问题、对解决网贷市场上缺乏平台风险性高低有效信号的问题都起到了正向作用,有助于互联网融资市场的有效性提高。 相似文献

This paper develops a platform‐based influencing factors model which considers value perception, risk prevention measure, non‐default experience, trust and incentive gap, to better examine the impact of platforms on investors’ satisfaction and lending intention based on the Chinese market. The results reveal that the first four factors positively influence the satisfaction of the investors, while the incentive gap has a negative impact, and there is a positive association between investors’ satisfaction and lending intention. Some specific features of China’s online lending market are identified, which provides valuable insights for online lending platforms and the government. 相似文献

ABSTRACTNatural language query systems over RDF data need to rely on the semantic relations in query. First, we propose the new crowdsourcing model that used to produce semantic relations dataset. The model not only inherits completeness of the iterative model and accuracy of the parallel model, but also saves human resources. Second, we mine the rules of semantic relation recognition from the correlations between dependency structures and semantic relations. Third, we propose an algorithm of semantic relation recognition for natural language query over RDF data, and experiments demonstrate that it can recognize more semantic relations than existing methods. 相似文献

Mobile channel additions have been shown to increase consumer-brand relationships, brand satisfaction towards and overall purchasing from a retailer, but what is less apparent is whether shareholders are fully rewarded for retailers’ mobile channel additions. Results from an event study on 115 announcements relating to mobile app additions of publicly traded U.S. retail firms between 2009 and 2016 indicate that the stock market responds generally positively to mobile app additions, but specifically to the two mobile app addition types. Stock market responses to search-related and purchase-related app additions are moderated by firm size, product category, and target customer age. For announcements of search-related apps, the market responds more positively to product retailers than to service retailers, and to small firms than large ones. For announcements of purchase-related apps, the market responds less positively to firms that target younger customers than firms who do not especially target them. 相似文献
