摘要：During this decade,many countries have experienced natural and accidental disasters,such as typhoons,floods,earthquakes,and nuclear plant accidents,causing catastrophic damage to *** the end of 2019,all countries of the world are struggling with the COVID-19 and pursuing countermeasures,including inoculation of vaccine,and changes in our lifestyle and social *** these experiences have made the residents in the affected regions keenly aware of the need for new infrastructures that are resilient and autonomous,so that vital lifelines are secured during calamities.A paradigm shift has been taking place toward reorganizing the energy social service management in many countries,including Japan,by effective use of sustainable energy and new supply ***,such new power sources and supply schemes would affect the power grid through intermittency of power output and the deterioration of power quality and ***,new social infrastructures and novel management systems to supply energy and social service will be *** this paper,user-friendly design,operation and control assist tools for resilient microgrids and autonomous communities are proposed and applied to the standard microgrid to verify its effectiveness and performance.

摘要：随着数字化技术的广泛应用,传统的戏剧艺术形态也在发生翻天覆地的变化。然而受传播设施的限制,戏剧文化未能在世界媒介中得到很好的发展。为此,数字新媒体技术应运而生,成为当下创作和传播戏剧的重要途径。本文通过叙述数字媒体的概念特点以及数字媒体对戏剧演出创作、传播的影响,凸显了数字媒体的优越性。

摘要：介绍了将既有建筑改建为超市建筑时基础、梁、柱、板的一些加固与节点构造的设计方法 ,并提出建筑改建时加设连接体、楼梯、电梯、自动扶梯、柱间支撑、卸货平台、广告牌、设备基础、室外道路、停车场等的做法 。

摘要：不知道是不是每个导演都偏爱长镜头,但我对长镜头有点'执念'。拍五芳斋的《招待所》,环时并没有拍板要一镜到底,我们提出来并且实现了。《招待所》的创作背景是五芳斋出了一款限量发售的磁悬浮粽子,它下面是一个方形底座,然后粽子装在金字塔形的容器中,环时给五芳斋提供了时光岭招待所的创意,就是把宇宙裹成一个粽子.

摘要：高校思想政治教育的根本任务是立德树人,课程思政要求教师在专业课程的教育中充分发挥育人功能,将思政教育融入专业教育。在国土空间规划体系整合的背景下,以“土地利用规划学”课程思政建设为研究对象,阐释了课程思政建设的原则和目标,探索了思政元素融入的路径,研讨了融入思政教育的教学设计,以期为土地资源管理专业中“土地利用规划学”课程思政的建设提供依据和方向。

摘要：本文阐述将一种自适应多相变换器(AMPC)用作适配级来提高光伏系统的功率转换链的效率和可靠性。为了说明AMPC的优点,文中首先介绍了单相和多相变换器效率的概念。针对光伏系统连续变化工作点的主要特性,提出了控制法则也要保证高的转换效率,而且设计了实验性样机来评估该适配级的性能。

摘要：设整数β(ρ,v,k)是最大部分平行类大小为ρ的任意(v,k)-填充设计中所包含的最大区组数目.对于k=3,该问题由Stinson (2021)引入并研究.本文主要研究k=4的情形,获得β(ρ,v,4)的上下界.本文给出最大部分平行类大小为ρ的(v,4)-填充设计的具体构造.对于小的ρ值,所构造的填充设计的区组数非常靠近上界β(ρ,v,4).本文的一些方法可以推广到k>4的情形.

摘要：新媒体艺术的“新”应该体现在与传统艺术相比,其在探索和表现人类精神这一艺术基本主题上有什么独特的贡献。新媒体艺术的虚拟性叙事、多屏幕叙事等叙事方法与表现现代人的生存境遇有双向的默契。文章以《重返桃花源》的创作为例,分析如何运用多叙事的创作方法,以移步换景的方式展示都市人面对现代生活的尴尬与窘迫,以唤起观众对现代性的反思。

摘要：High-pressure ratio and wide operating range are highly required for a turbocharger in diesel engines.A recirculation flow type casing treatment is effective for flow range enhancement of centrifugal *** ring grooves on a suction pipe and a shroud casing wall are connected by means of an annular passage and stable recirculation flow is formed at small flow rates from the downstream groove toward the upstream groove through the annular *** shape of baseline recirculation flow type casing is modified and optimized by using a multi-point optimization code with a metamodel assisted evolutionary algorithm embedding a commercial CFD code CFX from *** numerical optimization results give the optimized design of casing with improving adiabatic efficiency in wide operating flow rate *** analysis of design parameters as a function of efficiency has been *** is found that the optimized casing design provides optimized recirculation flow rate,in which an increment of entropy rise is minimized at grooves and passages of the rotating impeller.

摘要：这份报纸在内并且在高速度的 Oxy 燃料(HVOF ) 外面象煤气的流动一样分析涂层粒子的行为由使用 quasi-one-dimensional 分析和数字模拟的热水花枪。在现在的分析的 HVOF 枪是一个向轴的方向有 2.0 的设计马赫数字的对称的会聚分叉的嘴。从现在的分析，速度的分布和飞在内并且在 HVOF 枪外面的涂层粒子的温度被预言。在现在的方法计算的枪的出口的涂层粒子的速度和温度与以前的试验性的结果同意很好。因此，计算的现在的方法被认为为预言 HVOF 气体和粒子流动有用。关键词可压缩的流动 - 超声的喷气 - 热水花 - HVOF CLC 数字 O357.
