光纤反射光谱在彩绘文物颜料鉴别中的应用研究

光纤反射光谱是一种完全无损的颜料鉴别方法,适合用于精美珍贵的彩绘文物颜料工艺研究。光纤反射光谱在国际文物研究领域已成为一种较成熟的方法,而国内由于缺乏反射光谱数据库限制了其应用。因此,本研究探讨了颜料颗粒度和产地对反射光谱的影响,对蓝色系、绿色系、红色系和黄色系颜料的反射光谱特征进行归纳总结,并将其用于故宫博物院建筑彩画和书画文物的颜料分析中,证明光纤反射光谱确实是一种快速有效的颜料分析方法。     

人流联系和经济联系视角下区域城市关联比较——基于手机信令数据和企业关联数据的研究

手机信令数据所代表的人流联系与国内外研究常用的企业关联数据在测度城市关联存在何种差异,尚缺乏明确的研究。本文以江西省北部地区为研究对象,分别以手机信令数据、企业关联数据测度城市关联,比较了两种城市关联与城市之间空间距离、人口规模的关系,比较了两种城市关联网络的层级、结构、腹地。主要研究发现：人流联系不仅集中在城市周边地区,而且集中于较高等级城市之间;经济联系则主要集中在较高等级城市之间。人流联系、经济联系受到城市人口规模影响均较小。人流联系显著地符合幂函数空间衰减规律。手机信令数据和企业关联数据是两种不同的城市关联数据,但可互为补充,较为全面地反映城市关联。     

运用苏裱技艺修复洪范《水墨竹石图》轴

洪范《水墨竹石图》轴为苏州博物馆三级藏品,此画笔墨简练,技法娴熟,饶有意趣,但画作破损霉变,酸化开裂,亟待修复保护。为此,运用苏裱技艺的修旧如旧技巧,制定详细的修复方案,通过去污、揭褙、隐补、胶矾加固、接笔全色等苏裱传统修复方法,历时半年,对破损的洪范《水墨竹石图》进行了修复,使其得到了及时有效的保护。     

Crowdsourcing Model Research for the Identification of Post-Earthquake Rescue Objects

The quick and accurate identification of post-earthquake rescue objects can minimize the casualties and property loss caused by earthquakes. With the rapid development of remote sensing technology, rescue objects can be identified through high-resolution remote sensing images. There are two main categories of approaches to identify rescue object through high-resolution images: automatic extraction by a computer and visual judgment by professionals. Although results can be obtained quickly by using automatic extraction, the accuracy of the results is unacceptably low. For visual judgment, the large demands for time and professionals restrict its wide practical application. In this study, we introduce crowdsourcing into the identification of post-earthquake rescue objects. First, we integrate the advantages of the computer and crowdsourcing, which means that the computer takes advantage of the speed of information processing, while crowdsourcing makes full use of human recognition capabilities. Second, we take visual judgment tasks out of the hands of professionals and entrust the tasks to workers in a crowdsourcing platform. Not only are the human resources infinite, but we can also improve the efficiency of identifying rescue objects. Third, we propose a crowdsourcing model that improves the quality of the results and saves human resources. Finally, experimental results demonstrate that our solution is feasible.     

一度梅花一度春

好一个新世纪的金秋,好一个新面貌的首都,好一个新的起点。十七大所作出的每一项一项决策、提出的每一条方针、表达的每一个思想、设置的每一个目标,都富有历史性意义。百岁老人帅孟奇曾诗云:"一度梅花一度春,傲霜战雪岁迎新。漫山争艳向阳发,粗枝老梅绿叶生。"艺术性地表达了这种政治性的意蕴。     

Real-Time Dynamic Hybrid Testing Coupling Finite Element and Shaking Table

In this article, a Simulink simulation block with the finite element function is developed on the basis of S-function and implemented as the numerical substructure of real-time dynamic hybrid testing. Thereby, a real-time dynamic hybrid testing system coupling finite element calculation and shaking table testing is achieved. Using the developed system, a shear frame mounted on the soil foundation is tested, in which the shear frame is simulated as the physical model and the foundation is simulated as the finite element model with 132 degrees of freedom. Several cases of the dynamic behavior of soil-structure interaction are studied.

《奉贤县续志》序

以前志主编的身份,在离开家乡近20年之后能为家乡续志写序,我感到无上荣光。我想,这是相当特殊的个例,就是在全国方志界也许不会很多吧。     

古诗词新解二题

本认为,唐朝张继《枫桥夜泊》中的“愁眠”应解释为“愁眠”,而不应解释为“怀着客愁睡下”之类;宋朝苏轼《赤壁怀古》中的“多情应笑我”应解释为“多情应笑我”,而不应解释为“应笑我多情”的“倒装”。过去的解释不准确,是由于忽视了汉语谓词性成分转指这一语法规律所造成的。
