高效的电力营销稽查管理模式构建

营销稽查是电力营销工作内部控制约束机制的重要环节。由于目前中国电力企业的营销稽查工作仍然存在很多问题,因此从管理方式、管理制度、管理内容和管理手段四个方面系统性地研究如何构建高效的电力营销稽查管理模式,可以有效提高稽查管理水平。在稽查系统内施行垂直管理,同时构建电力营销稽查、电费计算和电价监管“三位一体”的稽查管理模式能够充分发挥电力营销稽查的作用,形成有利于规范、高效、有序稽核管理的长效机制。     

电动汽车充换电服务收费模式探析

目前,我国充换电服务收费政策仍为空白,甚至没有将充换电服务列入物价清册。有电动汽车的地方,如杭州市是按里程收费;北京和安徽等地是按一般工商业电价和充电电度收费。根据国家电网企业是唯一的供电主体,其向充换电设施供电与充换电设施为用户提供充换电服务的资产界面自然分开的实际,我国可实行供电和充换电服务分开定价的办法。充换电设施供电服务收费执行电网供电价格;充换电服务收费应由市场竞争确定。同时,要深入研究政策扶持和财政补贴问题,要制定促进产业发展的充换电服务价格机制。     

Understanding the cell phone effect on vehicle fatalities: a Bayesian view

This article examines the potential effect of various factors on motor vehicle fatality rates using a rich set of panel data and classical regression analysis combined with Bayesian Extreme Bounds Analysis (EBA), Bayesian Model Averaging (BMA) and Stochastic Search Variable Selection (SSVS) procedures. The variables examined in the models include traditional motor vehicle and socioeconomic factors. In addition, the models address the effects of cell phone usage on such accidents. The use of both classical and Bayesian techniques diminish the model and parameter uncertainties which afflict more conventional modelling methods which rely on only one of the two methods.     

Entering an era of ferment – radical vs incrementalist strategies in automotive power train development

Incremental improvement of a deeply embedded technology system has been a hallmark of the automotive industry for a very long time. Efforts to develop alternatives have repeatedly failed. This paper analyses how Toyota started to challenge this pattern in the late 1990s, by the architectural innovation embodied in Prius, the first mass-produced hybrid-electric car. This is followed by an account of how key competitors reacted by accelerating their incremental innovation efforts, in an era when concerns over fuel prices and greenhouse gas emissions increased demand for environmentally sound vehicles. The paper builds on records of patenting and performance of actually marketed models to analyse the unfolding technology competition. It also considers the most probable technologies on the market in a 10–12 year timeframe, and further explains how different technology strategies put competing firms in different positions in an era of ferment.     

某陆空汽车变桨距式桨毂设计

针对某陆空汽车变桨距式螺旋桨功能特点,对变桨距机构及螺旋桨桨毂进行设计。为减小起飞重量,对桨毂进行轻量化设计,分别在陆空汽车垂直起降和平飞的工况下进行仿真计算,并对桨距式桨毂在离心力方向、摆振方向、挥舞方向的应力、应变进行了校核。分析结果表明,该变桨距式桨毂设计能够满足陆空汽车各工况强度要求。     

Old timers and new mobile lifestyles

Retired persons have begun to establish new forms of communities that are adapted to their contemporary needs. Such communities are often temporary and associated with new lifestyle adaptations. Mobile travel has permitted one new mode for retirees, particularly for those who adopt full-time mobility, permitted by recreational vehicles, and actively engage in new styles of retirement life. This example partially refutes disengagement theory, as it has most generally been employed. Restricted use of disengagement theory following lifestyle changes among retirees is recommended.     

分层教学在工厂电气控制设备课程中的尝试

分层教学思想旨在课堂教学中面向全体学生，促使人人成功。分层教学指协调教学目标和要求，将教学要求置于各层次学生的最近发展区之中，同时调动学生学习可能性中的易变因素，使教学要求与学生的学习可能性相互适应。通过实施分层授课、分层训练、分层辅导、分层评价，以达到各类学生接受效应、共振效应。使各类学生的素质达到分层发展的目的。
