新疆第三产业发展与人口城市化协调发展研究 [PDF]

open access: yes, 2008
城市化进程和第三产业的发展是一个互动发展的过程。基于城市化与第三产业互动机制的原理,本文分析了1979—2005年期间新疆第三产业及人口城市化的发展轨迹,对新疆人口城市化与第三产业增加值占GDP的比重、第三产业就业比重、人均第三产业产值等指标进行相关性分析。结果表明:(1)新疆城市化率与第三产业增加值占GDP的比重的相关性较显著,说明第三产业的发展变化对新疆城市化具有很强的推动和促进作用;(2)新疆城市化率与人均第三产业产值显著相关。基于此提出新疆应加快产业结构调整,积极促进第三产业内部结构的优化 ...

基于区块链和通证经济的跨国跨洲电力市场机制设计

open access: yes智能科学与技术学报, 2019
全球能源互联网旨在构建以电力消费为核心的能源模式,跨国跨洲电力交易是推动其发展的必要条件和有效途径。首先分析跨国跨洲电力交易面临的问题,提出了基于区块链和通证经济的跨国跨洲电力市场设计思路。然后,将跨国跨洲电力市场的组成分为5个部分,并分别对这5个部分进行了描述与建模。最后,利用等比例放大的IEEE 39节点系统,对本文所提市场进行了仿真与分析。仿真结果表明,基于区块链和通证经济的跨国跨洲电力市场可以保证跨区域、多主体电力交易的有效实施,同时有利于激励发电商使用清洁能源参与电力市场。

酯化酶粗酶制剂工业化生产与应用 [PDF]

open access: yes, 1994
浓香型大曲酒质量的优劣,取决于酒体中己酸乙酯含量的高低,而在生产发酵过程中,酯的形成比较缓慢,因而生产周期长;成本高。该项目从大曲中分离德育出一株活性高而稳定的酯化酶生产菌株,由该菌株生产粗酶制剂,方法简单易行。将该酶制剂应用于生产,可缩短发酵期1/3,优质酒率提高10个百分点,而且可提高己酸乙酯含量,成效显著。现已建成年产酯化酶粗酶制剂1000吨,高酯调味酒100吨的生产线,经试生产工艺合理,运行正常,操作方便,产品的产量与质量均达到设计要求。与传统工艺相比,可缩短发酵周期3/4~2/3 ...

低温蒸发联合臭氧催化氧化处理精细化工污水

open access: yesGongye shui chuli, 2020
某生产清洗剂类化工品的企业属典型小型精细化工企业,生产污水只能采用企业自理的处理方式,随着企业产品种类和数量的增多,产生的污水量及污水污染物已远超过原处理设施的处理能力。本研究采用低温蒸发联合臭氧催化氧化的短流程处理工艺,组装成移动式一体化处理设备处理该废水,处理结果表明,出水COD ≤ 30 mg/L、总磷≤ 0.5 mg/L、浊度≤ 6.0 mg/L、色度接近0,达到国家一级排放标准和回用标准。
