Effect of vanadium on dynamic continuous cooling transformation behavior of medium-carbon forging steels

引用

Journal of Iron and Steel Research International 2017年第6期24卷 641-648页

作者： Wei-jun Hui Na xiao xiao-li Zhao Yong-jian Zhang Yu-feng wu School of Mechanical Electronic and Control Engineering Beijing Jiaotong University Beijing 100044 China Faculty of Materials Science and Engineering Kunming University of Science and Technology Kunming 650093 Yunnan China

Dynamic continuous cooling transformation （CCT） behavior of medium-carbon forging steels microalloyed with different V contents up to 0.29% was investigated by means of dilatometric measurement, microstructural observation and hardness measurement. The re- sults showed that the dynamic CCT diagrams were similar and the main difference was that the fields of the transformation products were shifted to the right side of the diagrams with the increase of V content, and this effect was more noticeable with an addition of 0. 290/00 V. The At1 and At3 temperatures showed increasing trends with increasing V content, while the critical cooling rates decreased with increasing V content. The increase of V content re- sulted in significant increase of hardness and this tendency was enhanced with increasing cooling rate until the formation of acicular ferrite （AF）. A promising approach of remark- ably improving the toughness of ferritic-pearlitic medium-carbon forging steels with suit- able V addition and the introduction of AF without notable penalty on its strength level was suggested.

Insights into the Organotemplate-Free Synthesis of Zeolite Catalysts

Engineering 2017年第4期3卷 567-574页

As the most important nanoporous material, zeolites, which have intricate micropores, are essential heterogeneous catalysts in industrial processes. Zeolites are generally synthesized with organic templates under hydrothermal conditions; however, this method is environmentally unfriendly and costly due to the formation of harmful gases and polluted water. This article briefly summarizes the role of organic templates and describes designed routes for the organotemplate-free synthesis of zeolites, aided by zeolite seeds and zeolite seeds solution. Furthermore, this review explicates that the micmpore volume decreases with an increase of the Si/Al ratios in the organotemplate-free synthesis of zeolite products, where Na^＋ exists as an alkali cation. This feature is very important in directing the synthesis of zeolite catalysts with controllable Si/AI ratios under organotemplate-free conditions, and is thus important for the efficient design of zeolites.

“辨体”是贯穿贺复征《文章辨体汇选》的主要批评方法。他采取“省略”“改写”“补充”等方式,对“序题”进行经典化构建,形成新的序题模式。在选文编次上,不拘泥于辨析文体的体裁、形式等外在要素,而依次遵循“体—时—人”的层级结构,既继承“原释选敷”的辨体法,又独创了“四部整合”“选己入集”“裁篇摘句”的辨体法,这充分体现了其对“因文立体”的灵活使用。其“尊体”观集中表现在对“文章以体制为先”的继承与发扬上,其“破体”观则以变体为常态,以别体为创体,因此深化并完善了辨体批评的实践路径和目标,具有辨文体价值、析文体风格变化、见文体演变轨迹、示文体写作范例的重要意蕴,使《文章辨体汇选》成为明代具有集大成意义的文体总集。

Composite Quantile Regression Estimation for Left Censored Response Longitudinal Data

引用

Acta Mathematicae Applicatae Sinica 2018年第4期34卷 730-741页

作者： Li-qun xiao Zhan-feng WANG Yao-hua wu School of Economics and Statistics Guangzhou University Guangzhou 510006 China Department of Statistics and Finance The School of Management University of Science and Technology of China Hefei 230026 China

For left censored response longitudinal data, we propose a composite quantile regression estimator（CQR） of regression parameter. Statistical properties such as consistency and asymptotic normality of CQR are studied under relaxable assumptions of correlation structure of error terms. The performance of CQR is investigated via simulation studies and a real dataset analysis.

针对现有孪生网络跟踪算法仅使用主干网络最后一层的特征进行相似度匹配,以及缺少有效模板更新策略的问题,提出基于多尺度特征融合和自适应模板更新的孪生网络跟踪算法。首先,结合深度过参数化卷积设计非填充单元,提取更深层的前景特征和语义背景;然后,设计新的全局-局部特征融合模块,充分聚合浅、中层特征的全局和局部信息,捕获丰富的浅层外观特征和中层过渡特征;最后,采用自适应模板更新机制在线更新模板。为验证算法的有效性,在公开数据集上对所提算法进行详尽评估,实验结果显示,所提算法在OTB2015和VOT2018数据集上的精确度分别达到0.878和0.588,GOT10K数据集上平均重叠率达到0.526,优于其他主流算法。

Landscape design method for a green community based on green building design theory

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2010年第9期11卷 691-700页

作者： Hong-feng GUO Jian GE Miao YUE xiao ZHOU wu JIN Architectural Design and Research Institute Zhejiang University Hangzhou 310027 China Department of Architecture Zhejiang University Hangzhou 310058 China

Landscape design for a green community should be favorable for the ambient ecological environment and for enhancement of both the local climate of a residential area and the environmental quality of life. This paper presents optimization methods for plant landscape design that take account of results of comparisons of noise reduction effects, heat island temperature decreases and effects on ventilation. These methods are based on different plant configurations and various luminous environments, such as exterior sunshine and shaded areas after the simulation of exterior luminous, acoustic and thermal environments of a residential area using the analytic software ECOTECT, CADNA/A, and PHEONICS. Three different types of residential buildings are simulated including a faculty apartment in the Xixi Campus of Zhejiang University, the Huaqing Villa and the Gangwan Jiayuan faculty apartment of Zhejiang University, China, based on green building design theory. In addition, the methods and process flow of landscape design of green residential areas are also described for the improvement of the exterior physical living environment.

Methylation in esophageal carcinogenesis

引用

World Journal of Gastroenterology 2006年第43期12卷 6933-6940页

作者： Da-Long wu feng-Ying Sui xiao-Ming Jiang xiao-Hong Jiang Department of Pharmacology School of Medicine Collegeof Jiaxing Jiaxing 314001 Zhejiang Province China

Genetic abnormalities of proto-oncogenes and tumor suppressor genes have been demonstrated to be changes that are frequently involved in esophageal cancer pathogenesis. However, hypermethylation of CpG islands, an epigenetic event, is coming more and more into focus in carcinogenesis of the esophagus. Recent studies have proved that promoter hypermethylation of tumor suppressor genes is frequently observed in esophageal carcinomas and seems to play an important role in the pathogenesis of this tumor type. In this review, we will discuss current research on genes that are hypermethylated in human esophageal cancer and precancerous lesions of the esophagus. We will also discuss the potential use of hypermethylated genes as targets for detection, prognosis and treatment of esophageal cancer.
