Characteristics of electricity consumption of different industry types considering atmospheric condition

Reducing greenhouse gases (RHG) is going on actively in the international movement. In the field of architecture, RHG is an inevitable work. To establish a plan for RHG, firstly we need to reduce energy consumption. Greenhouse gas generated by energy consumption is the main cause of global warming. For this we should know that how much electricity consumption we use. The research targets of this study are commercial buildings with various businesses. Their electricity consumption was analyzed by business units rather than buildings. Each business was divided into 13 sectors according to industrial classification and electricity consumption was analyzed for each industry. For commercial buildings, the electricity consumption is done by the private sector and construction management is an autonomy system in private instead of an integrated management system. In this study, we classified and analyzed the electricity consumption characteristics according to collected data, analyzed the relationship between the electricity consumption with atmospheric temperature through SPSS, and developed an electricity prediction model.

健身秧歌对60～65岁老年女性体质的影响

选取30名自愿参加健身秧歌锻炼且没有参加其它锻炼形式的60～65岁老年女性作为实验组,并随机选取27名同年龄段没有参与任何形式健身锻炼的老年女性作为对照组．运用实验法经过20周系统的健身秧歌锻炼,对实验前后两组人群体质状况进行比较研究,探讨健身秧歌锻炼对老年人体质的影响,从而为广大老年女性参加健身秧歌运动提供一定的参考．     

《非诚勿扰》节目失范行为的传媒环境学解读

传媒环境学派一直将传播媒介视为考量传播效果的关键性因素。将《非诚勿扰》节目中出现的“作秀”、“缺乏真实性”和“言语粗俗”等问题置于传媒环境学视域下进行考察,能发现该节目出现失范行为的本质原因在于电视媒介本身,而非其他。     

On theory and methods for advanced detonation-driven hypervelocity shock tunnels

This study describes theory and methods for developing detonation-driven shock tunnels in hypervelocity test facilities. The primary concept and equations for high-enthalpy shock tunnels are presented first to demonstrate the unique advantage of shock tubes for aerodynamic ground-based testing. Then, the difficulties in simulating flight conditions in hypervelocity shock tunnels are identified, and discussed in detail to address critical issues underlying these difficulties. Theory and methods for developing detonation drivers are proposed, and relevant progress that has advanced the state of the art in large-scale hypersonic test facilities is presented with experimental verifications. Finally, tailored conditions for detonation-driven shock tunnels are described, laying a solid foundation to achieve long test duration. This interface-matching key issue encountered in developing shock tunnels has been investigated for decades, but not solved for detonation drivers in engineering applications.     

正交试验设计优化气相色谱分离

讨论了气相色谱分离甲醇、乙醇、丙酮、异丙醇混合溶液的条件.通过前期试验发现乙醇和异丙醇的分离较难,所以运用正交实验设计法,确定最佳操作参数,获取优化的分离度.采用正交实验设计法对气相色谱分离过程中所采用的温度、流量、程序升流和尾吹四个主要因素进行了试验,通过有交互作用和无交互作用作正交试验设计,确定了最佳的操作条件：炉温45℃、初始载气流量6ml/min、程序升流4ml/min、加尾吹,且尾吹的影响最显著.     

鱼与熊掌可以兼得吗？——营商环境对创业数量和创业质量的影响研究

我国创业活动数量和质量呈现区域差异的特征,塑造激发创业活动数量和质量协同增长的营商环境是缓解这种差异、促进经济高质量发展的重要举措。营商环境对创业活动数量和质量的影响机制有何不同,是否存在一种或几种营商环境组态能够同时产生高创业数量和高创业质量,这是目前学界尚未厘清的问题。基于组态视角,本文采用NCA和QCA相结合的研究方法,以31个省份为研究案例,分别探究营商环境单个要素是否是产生高创业数量或创业质量的必要条件以及营商环境组态下产生高创业数量和创业质量的不同路径。结果发现：单个营商环境要素不构成高创业数量或高创业质量的必要条件,但提升人文环境对于高创业数量/高创业质量的产生发挥普适作用;产生高创业数量有1条驱动路径,即人文—市场驱动型;产生高创业质量有2条驱动路径,即人文—政务驱动型和人文—法律政策支持下市场驱动型;存在1种营商环境组态可以同时产生高创业数量和高创业质量,即高市场环境、高政务环境、高人文环境为核心条件,辅以非高法律政策环境为边缘条件。研究结果为揭示促使区域创业数量和质量协同发展、缩小区域间创业活动差异的营商环境组态实现路径提供理论指导。     

现代汉字中非同音声旁之研究

现代汉字声旁一般分为同音声旁和非同音声旁。非同音声旁因与其含旁字不同音而被各路专家判为“都不表音”,并失去表音功能。文章分类描写了非同音声旁在含旁字中的表音实际,通过统计研究,认为非同音声旁并非“都不表音”,经过处理,其中至少有142个非同音声旁所带的749个相同读音的含旁字,能按声旁音读准字音。     

由书法创作到潜意识的阐释

书法书写中潜意识的形成以扎实的基本功和渊博的字外涵养为支撑点,经典的“过去经验”是书法创作者潜意识形成的基本的材料。书法创作者的心态环境是潜意识外化的基本条件。成功的书法创作是书法作者潜意识充分外化的表现。
