节水农业持续发展研究
贾大林,司徒淞,王和洲
中国生态农业学报 , 1994,
Abstract: 本文根据商丘试区多年研究成果与实践，结合我国水资源短缺的现状和黄淮海平原旱涝盐碱灾害形成的特点，提出节水农业持续发展的基础是改善农业生产条件，它通过治水、改土、调整农业生产结构和良种良法，以实现高产、优质、高效农业。农业持续发展的重要限制因素是水，重点研究了节水农业技术体系，即提高水的利用率和水的利用效率以及实现节水农业生产分区的途径及效益。

Abstract: Based on several years study at Shangqiu Experimental Station,and features of drought,water-logging and soil salinization in part of Huang-Huai-Hai Plain and water shortage situations in China,it was pointed out in this paper that the bases for sustainable development of water-saving agriculture in this region is to develop high-production,high-quanlity and high-efficiency agriculture by controlling water,increasing soil fertility,adjusting agro-structure and breeding new varieties.The main limiting fctor to sustainable agricultural development is water shortage,then increasing water use efficiency is the key to solve water crisis in this region.
贪婪与恐惧——对上海股市投资者处置效应的实证研究
Greed and Fear—An Empirical Study on Investors’ Disposition Effect on the Shanghai Stock Exchange  [PDF]
施歌, 司徒大年
Finance (FIN) , 2019, DOI: 10.12677/FIN.2019.93016
Abstract:
本文利用2016~2017年间上海股市5000余万个活跃账户的交易数据，对投资者的处置效应进行了实证分析，并考察了不同类别投资者和不同市场表现对处置效应的影响。我们的研究发现，上海股市的投资者整体上存在处置效应行为，分组分析显示，中小散户投资者存在显著的处置效应，但大户和机构投资者并不存在处置效应，在个人投资者中，女性投资者的处置效应程度要高于男性投资者，并且个人投资者的处置效应随年龄的增长而愈加显著。此外，处置效应程度在市场环境变好的情况下会下降，而在市场环境变坏的情况下会上升。这些研究结果有助于进一步分析股票市场中投资者的认知偏差和市场的无效率现象。
Using the transaction data of more than 50 million active investors on the Shanghai Stock Market during 2016 to 2017, we find that the “disposition effect”, investors’ reluctance to crystallize losses and relative eagerness to realize gains, is pervasive in aggregate. Further results by investor type indicate small individual investors are reluctant to realize losses, while larger individual investors and institutional investors are not. Our novel findings include that (a) although male investors realize gains at a faster rate than female investors, they exhibit a lower preference for realizing gains rather than losses, (b) the disposition effect of individual investors becomes more prominent as the age grows, (c) there is evidence that the propensity of disposition effect declines following strong market performance.
煤油超燃冲压发动机性能分析
司徒明？
推进技术 , 1998,
Abstract: 对近期有应用前景的碳氢燃料（煤油）超燃冲压发动机性能进行了计算。探讨了固定几何尺寸（不可调）的超燃冲压发动机有效推力系数、有效比冲和有效单位推力等主要性能参数变化的定量范围。计算表明，几何尺寸不可调的煤油超燃冲压发动机将可能成为巡航马赫数６左右的导弹动力装置。
HSB信息隐藏算法设计与实现
The Design and Implementation of HSB Information Hiding Algorithm  [PDF]
张淞, 范明钰
Hans Journal of Data Mining (HJDM) , 2012, DOI: 10.12677/hjdm.2012.22002
Abstract: 本文首先介绍BMP文件结构及特点，再介绍LSB算法，针对传统LSB算法可嵌入图像大小的限制，提出了一种有损信息隐藏算法HSB(Highest Significant Bits)，此算法基于24位BMP图像文件，有效的增加了嵌入图像的大小，分别对于图像型和文字型图像进行实验证明。实验编程环境为VS2008，结果证明了此算法的正确性和有效性。
This dissertation first introduces the structure and characteristic of BMP file and then the LSB algorithm. A lossy information hiding algorithm named HSB (Highest Significant Bits) is proposed in order to break the limit of the embedded image by the traditional LSB algorithm. The new algorithm is based on 24-bit BMP image and increases the size of the embedded image, which is applicable to both image and text. The development environment is VS2008 and it demonstrates the correctness and effectiveness of the new algorithm.
国有资本经营预算制度的几个基本问题
欧阳淞
法学家 , 2007,
Abstract: 建立健全国有资本经营预算制度具有现实必要性和重要性，是一项涉及到诸多方面的综合系统工程。而有关国有资本经营预算的性质、编制主体以及国有资本经营预算内容和运行机制等基本问题的探讨，尤其是其与政府公共预算制度关系的疏理，是构建科学合理的国有资本经营预算体系暨制度、确保国有资本经营预算规范运作、实现国有资本经营预算法治化的理论基础和前提。本文对这些问题进行了较为全面、系统的探讨，并提出了解决问题的对策建议。

天津市金融影响进出口贸易的动态关系研究——基于VAR模型
A Study on the Dynamic Relationship of Financial Influence on Import and Export Trade in Tianjin—Based on VAR Model  [PDF]
徐淞
Statistics and Applications (SA) , 2023, DOI: 10.12677/SA.2023.125124
Abstract: 本文旨在研究天津金融对进出口贸易的动态关系，并以VAR模型为基础进行分析。通过构建VAR模型探究天津市金融因素(进出口总额、金融机构数量、中外资金融机构存款余额、中外资金融机构贷款余额)与进出口贸易之间的关联。通过脉冲响应和方差分解从而揭示金融对进出口贸易的影响机制和程度，为相关政策制定者和决策者提供重要的政策参考，以促进天津市的进出口贸易发展。最终根据结论给出相应的建议。
This paper aims to study the dynamic relationship between Tianjin Finance and import and export trade, and analyze it based on VAR model. This paper explores the correlation between financial factors (total import and export volume, number of financial institutions, deposit balance and loan balance of Chinese and foreign-funded financial institutions) and import and export trade in Tianjin by constructing VAR model. Through impulse response and variance decomposition, the influence mechanism and degree of finance on import and export trade are revealed, which provides important policy references for relevant policy makers and decision makers to promote the development of import and export trade in Tianjin. Finally, the corresponding suggestions are given according to the conclusion.
我国工程建设利用粉煤灰概况
司徒一凡
工业建筑 , 1991, DOI: 10.13204/j.gyjz199111013
Abstract: 粉煤灰是电厂排放的工业废渣之一。1台30万kW机组一年排放的粉煤灰为42万t,既严重污染环境,又要设置较大规模的堆放场地,需耗巨资进行处理。为了合理利用资源,增加社会财富,提高经济效益,保护环境,变废为宝,化害为利,世界上许多国家和联合国有关国际组织都将粉煤灰的开发利用列为重要科研课题。我国在工程建设中应用粉煤灰始于50年代,那时主要是把粉煤灰应用制造建材制品和用于混凝土中。60年代,以粉煤灰为原料的建材制品得到了一定的发展,粉煤灰及其制品的产品质量标准及设计与施工规程等相继产生。进入80年代,粉煤灰在建筑筑路、筑坝、工程回填、掺入混凝土及砌筑砂浆等方面有了很大的发展。据统计,1988年全国粉煤灰利用量1420万t中,工程建设的利用量约700万t,占49%。
