作者 张慧哲 胡素端 《中国防汛抗旱》 2025年第2期59-63,92,共6页
为研究气候变化对降水的影响,选取大连南部地区大连气象站1951—2016年共66 a的降水数据,采用滑动平均法、Mann-Kendall检验、重标极差(R/S)分析法、Pettitt突变检验、滑动T检验、Morlet小波分析对年降水序列的趋势、突变、周期及降水... 为研究气候变化对降水的影响,选取大连南部地区大连气象站1951—2016年共66 a的降水数据,采用滑动平均法、Mann-Kendall检验、重标极差(R/S)分析法、Pettitt突变检验、滑动T检验、Morlet小波分析对年降水序列的趋势、突变、周期及降水演变趋势进行分析,结果表明:1951—2016年大连南部地区年降水时间序列呈现不明显下降趋势,且预测未来10 a降水仍维持减少趋势;年降水时间序列的突变年份为1979年;年降水时间序列存在4类尺度的周期变化规律,且存在4个明显的主周期,分别为58 a、19 a、25 a和5 a。降水事件以暴雨为主,历时以2 d为主,5 d及以上降水事件发生率与贡献率呈现显著下降趋势,中雨、1~2 d降水发生率与贡献率均呈现上升趋势。通过对降水演变规律的研究,为大连市水资源规划利用、预防旱涝灾害等提供一些参考依据。 展开更多

基于大连市污染物浓度、降水数据,从降水量大小、月变化、初始浓度等深入研究降水对气态污染物的清除作用。结果表明:SO_(2)、NO_(2)降水日比无降水日浓度分别下降36.5%、29.6%。污染物浓度随降水量增加而降低,降水量50 mm以上下降幅度... 基于大连市污染物浓度、降水数据,从降水量大小、月变化、初始浓度等深入研究降水对气态污染物的清除作用。结果表明:SO_(2)、NO_(2)降水日比无降水日浓度分别下降36.5%、29.6%。污染物浓度随降水量增加而降低,降水量50 mm以上下降幅度最大。当降水量为25.0—49.9 mm时,污染物的平均清洗率及正清洗比例达到较高水平。春季、秋季降水作用好于夏季,冬季可能更易出现吸湿增长。SO_(2)、NO_(2)的初始浓度与降水当日浓度存在正相关关系,当降水前SO_(2)初始浓度高于10μg/m^(3)或者NO_(2)初始浓度高于30μg/m^(3),降水的清除效果最优。同时以一次降水过程为例分析了气态污染物的变化。 展开更多

Public signs, as a city's "name card", have attracted wide attention. However,inappropriate translation of public signs are ubiquitous with some even cause misunderstandings for international visitors. In this paper, we first introduce the function of public signs, then through case analysis many problems are exposed and those errors bring a lot of inconvenience for foreigners who live and work in China.What's worse, to some extent, China's image and reputation will also be undermined.Finally, an appeal is made for a standardized translation of public signs and more research should be done and effective measures should be taken to improve the quality of the language environment and public signs translation. 展开更多

A process of "Methanol or Dimethylether to Olefins" developed by Dalian Institute of Chemical Physics (DICP), designated as the DMTO process, has attained great success in industrial scaling up testing. DICP, by collaborating with the Xinxing Coal Chemical Co., Ltd. of Shaanxi Province and the Luoyang Petrochemical Engineering Co. of the SINOPEC Group, operated successfully a 50t(methanol)/d unit for the conversion of methanol to lower olefins, with a methanol conversion of close to 100%, and a selectivity to lower olefins(ethylene, propylene and butylenes) of higher than 90%. On 23rd August, the industrial test project has passed a state appraisal. The experts of the Appraisal Group, headed by Prof. YUAN Qingtang, academician of Chinese Academy of Engineering, drew the conclusions that the DMTO process, by utilizing a proprietary SAPO-34 catalyst system and a recycling fluidized bed reaction system for the production of lower olefins from methanol, is the first unit in the world having a capacity of producing nearly ten thousand tons lower olefins per year. The technological level of the industrial test is at a leading position internationally. This accomplishment will provide a sound base for the subsequent commercialization of the DMTO process. 展开更多
