Along with the quick development of social economy, market competition has already entered into a new stage, namely brand competition era. This paper is to put forward scientifically rational countermeasures and suggestions through taking brand internalization theory as basis and starting from regional industry competitiveness. Thus it would increase regional industry competitiveness of brand.

二氧化碳(CO_(2))排放增加是全球变暖的主导因素,其中人为活动排放对全球CO_(2)浓度增长的贡献越来越大,然而当前我国对城市区域的大气CO_(2)监测相对缺乏.本文利用长三角地区背景站点(大明山站,DMS)2020年9月—2022年1月的CO_(2)在线观测数据,结合地面风的影响,对观测数据进行筛分,采用后向轨迹分析方法,探讨了长江三角洲地区大气CO_(2)季节浓度及源汇特征.结果表明,观测期间DMS大气CO_(2)平均浓度为(421.9±10.2)×10^(-6).CO_(2)浓度在冬季出现峰值(428.7±9.1)×10^(-6),夏季出现谷值(416.7±5.5)×10^(-6).春、夏、秋季,日变化波动分别在01:00、02:00、21:00出现峰值,在14:00、14:00、13:00出现谷值,而冬季呈相反趋势,峰值出现在13:00,谷值出现在00:***的CO_(2)浓度与风速呈显著负相关.春秋季,来自NE-ENE风向的局地风,夏冬季来自SSW-WSW的局地风,携带了较高浓度的CO_(2).白天DMS盛行上升风,不同风向CO_(2)浓度差异较大,浓度和风级呈正相关,夜晚DMS盛行下沉风,不同风向CO_(2)浓度差异不大,和风级呈负相关.此外,基于72 h后向轨迹的聚类分析发现,西南、西北和东南的气团向DMS传输的CO_(2)浓度比较均一,这表明DMS能够充分观测长三角区域混合均匀的大气本底特征.另外,潜在源区分析表明,DMS周边城市是重要的CO_(2)潜在源,人为排放对DMS大气CO_(2)浓度存在重要影响.

斯特林制冷机是目前高温红外探测器最主要的冷却方式之一。近年来随着红外探测器件技术研究的不断进步,所需制冷温度也有望进一步提高,为提高制冷机效率,减小其质量和体积带来了可能。相比于低温区斯特林制冷机,制冷温度的提升以及斯特林制冷机排出器的存在,使得压缩机活塞处阻抗相位接近90°,导致压缩机与冷指的阻抗匹配也更加困难,目前国际上缺乏160 K以上温区微型斯特林制冷机的深入研究。为同时满足红外探测器在高温区对制冷机结构紧凑性、高效等要求,本文针对制冷温度为220 K的微型斯特林制冷机开展压缩机与冷指间阻抗匹配特性研究,将压缩机活塞直径从原来的8.5 mm提高到10.5 mm。在此基础上,对结构及运行参数进行优化。当环境温度在-20~60℃内变化时,在220 K获得2 W制冷量,压缩机耗功均小于8 W。环境温度为25℃和60℃时,相对卡诺效率分别达到了10.4%和12.4%。

Background: The prevalence of Parkinson’s disease (PD), a chronic and progressive neurodegenerative disorder, is projected to increase twofold by 2030. Leucine-rich repeat kinase 2 (LRRK2) is the most commonly observed gene in both familial and sporadic PD cases. Notably, there is a substantial augmentation in motor activity during both larval and adult stages of zebrafish lacking the lrrk2 gene. Nevertheless, the precise genetic abnormalities accountable for eliciting these phenotypes in zebrafish are yet to be elucidated. Methods: Real-time polymerase chain reaction (PCR) was conducted on zebrafish larvae at 6 days post fertilization (dpf) belonging to both the wild-type and lrk2(-/-) groups. Guide RNA was designed and subsequently employed in the PCR process. Electrophoresis was performed to facilitate identification. Results: The expression of CNTF mRNA was significantly diminished in lrrk2(-/-), in comparison to the wildtype zebrafish larvae. This finding implies that CNTF may have crucial implications in the regulated functioning of lrrk2, which is widely acknowledged as the predominant genetic factor contributing to hereditary PD. The primers for CNTF DNA were meticulously designed, and the electrophoresis results of the PCR product were subsequently presented. The wild type zebrafish embryos were meticulously prepared for micro-injection, and the resulting efficiency identification displayed the presence of the mutant PCR product, which exhibited the presence of several debris. Conclusions: The present study demonstrates the successful generation of CNTF mutant zebrafish using the CRISPR/Cas9 genome editing technique. Further investigations are necessary to deepen our understanding of the exogenous CNTF gene’s functionality.

This paper presents a modeling procedure for deriving a single value measurebased on a regression model, and a method for determining a statistical threshold value asidentification criterion of normal or abnormal states of machine wear. A real numerical example isexamined by the method and identification criterion presented. The results indicate that thejudgments by the presented methods are basically consistent with the real facts, and therefore themethod and identification criterion are valuable for judging the normal or abnormal state of machinewear based on oil analysis.

为研究垃圾焚烧炉渣集料(BAA)的胶凝特征,以强度试验分析BAA的水硬性和火山灰活性,并采用X射线荧光光谱仪、X射线衍射仪和扫描电子显微镜分析微观作用机理.结果表明,BAA含有水泥熟料矿物和活性SiO_2、Al_2O_3,体现出水硬性和火山灰活性特征.BAA中水泥熟料矿物遇水发生水化反应生成水化硅酸钙(C-S-H)凝胶和Ca(OH)_2,活性SiO_2、Al_2O_3在Ca(OH)_2激发作用下发生火山灰反应生成C-S-H凝胶、水化硅铝酸钙等水化产物;BAA与水泥、水混合后,除上述反应外,活性Al_2O_3在硫酸盐激发下也发生火山灰反应生成钙矾石.BAA在水泥中的火山灰反应有一定延后性.湿法处理、长时间堆放BAA的胶凝活性分别较干法处理、短时间堆放BAA低.
