德意志联邦共和囝是一个施行议会共和制的国家.联邦总统仅作为国家元首代表国家,总理是实质的政府首脑,决定国家大政方针。德国地处欧洲中部,是接壤邻国最多的欧洲周家,境内交通运输网络高度密集发达,部分高速没有速度限制, 相似文献

本文认为行业的定义非常重要,行业的定义非常重要。它不仅涉及到企业的行业归属问题,还涉及到相关法律法规及统计数据的有效性。所以行业的定义必须是官方的,以保证其严肃性。从美国对建筑涂料行业的定义来看,联邦和地方是有所区别的。地方定义包括了用于移动建筑的涂料而联邦没有。由此可见.美国对一个行业的定义是不同的。行业定义不同必然导致行业标准不一,进而阻碍行业的发展。 相似文献

近年来,随着淮安电网负荷的飞速增长,变电所需要增加容量,为了节约土地资源,降低线路负载率,110kV变电站建成扩大内桥接线的情况逐渐增多。扩大内桥接线的备自投对于提高这种接线方式的供电可靠性非常重要。本文主要讨论了淮安地区110kV万达变扩大内桥接线的备自投逻辑,并分析了与主变保护的闭锁关系。 相似文献

财政联邦主义的思想不断发展,新的联邦体制在世界各地不断诞生.然而,一个有效率并且保障公平的联邦体制的真正确立决不可能一蹴而就,有许多问题需要不断地摸索和完善.联邦体制的税制设计就是其众多问题中尤其重要的一个.本文正是以Roger R.Gorgon(1983)的<联邦制下的最优税制>为切入点,对联邦体制下的税制设计研究进行一次回顾和介绍,并从中得到一些促进我国税制改革的启示. 相似文献

The use of business simulation games plays a crucial role in teaching and learning even though it has been used for 60?years since the modern business simulation games started in 1955. Even previous studies have demonstrated the effectiveness of business simulation games used in teaching and learning; however, the major concerns that need to be addressed are related to sustainability issues. In the future, there is a requirement to embed the stages of employability into the curriculum, as well as in organizations, to bridge the gap between possessed skills and industry-required skills. 相似文献

A stochastic model of an international payments system is formulated with the assumptions that: (1) international reserves are held in the form of a key currency; (2) fixed exchange rates are subject to infrequent change; (3) deficit countries depreciate more readily than surplus countries appreciate. The model is implemented with historical data. Time paths for international reserves and prices under alternative assumptions are secured through Monte-Carlo simulation. The paths show that anti-inflationary policy by the key-currency country — viz, the United States — is easily multiplied by exchange-rate changes by other countries. 相似文献

Self-scanning represents a form of customer participation in service creation, a form of self-service and a technology-based service delivery device. This study, conducted within the large-scale retail sector, pursues a dual aim: firstly, to assess the link between satisfaction with self-scanning and some of its possible antecedents; secondly we intend to determine whether satisfaction with this service has any impact on consumers' overall opinion of the supermarket and their intention to patronise the store with greater frequency. The data show that both the sense of control and hedonic component have a positive impact on satisfaction with self-scanning and further bring to light that service satisfaction is an antecedent both of customers' opinion of the supermarket and their intention to patronise the store more frequently. 相似文献

针对离散非线性系统的状态平滑问题,基于Rauch-Tung-Striebel(RTS)理论设计了一种容积卡尔曼平滑器(Cubature Kalman Smoother,CKS),即容积Rauch-Tung-Striebel平滑器(RTS-CKS)。首先,基于经典贝叶斯状态估计理论框架,推导了状态概率密度分布形式的非线性系统最优平滑算法;其次,基于Rauch-Tung-Striebel理论,建立了相应的最优平滑递推算法;然后,将其与容积卡尔曼滤波算法相结合,建立了递推形式的RTS-CKS平滑器;最后,通过典型的纯方位跟踪模型验证了该平滑器的可行性和有效性。该平滑器为非线性系统的状态估计提供了新的估计算法。 相似文献
