陈洪绶是中国绘画史上承前启后的重要画家。他的人物画上溯汉魏、远承唐宋、融合元明,大胆突破成规,造型高古奇骇,风格独特,开启近代人物画新风。在视觉表现上富于装饰变形意味,与晚明士大夫阶层的尚奇审美趣味颇为契合,在中国美术史上具有重要地位。本文试图从文化认同和视觉表现的角度,通过对题材、意象化特征、笔墨造型、程式化语言、设色等方面的解析,来探讨陈洪绶人物画与国产动画的关系,特别是针对国产动画如何继承创新问题,以期带来某些启示。

The causal correlation or linkage between the East Asian Monsoon (EAM) intensity and rise/fall of Chinese dynasties recently proposed by high-resolution paleoclimate reconstructions is examined in detail. Aside from many exceptions to the correlation, both instrumental and historical climate records show strong spatial variations of rainfall on annual-to-decadal scales over eastern China. The relationship between rainfall and EAM intensity also exhibits regional disparity. These observations suggest: (1) Tak-ing paleo-proxy records from a single locality in eastern China to imply changes in drought/wetness as to affect the cultural and political history of China is fraught with uncertainty. (2) On annual-to-decadal scales, the thesis that δ18O in speleothems can be used as a proxy for the EAM strength lacks empirical underpinnings.

Development of Virtual Simulation System for Remote Collaborative Surface Machining

第18届国际真空大会

BiFeO3 （BFO） films which possess the magnetoelectric couplings and high polarizations have attracted a great interests. In general, the BiFeO3 （BFO） films have the rhombohedral phases. Under the compressive stress from the substrate, the strained rhombohedral （R） phase will transform to the tetragonal（T）-like monoclinic phase. In this study, we investigated the dielectric mechanisms of samples with different T-phase/R-phase ratios, which were controlled by various thickness-relaxed strains. The contribution of the interface between the electrodes and films, the phase boundary between T-phase and R-phase, and the bulk properties of the BFO were studied by the impedance spectrum. Contributions from different dielectric mechanisms can be distinguished by their characteristic relaxation times. Our results revealed that the dielectric properties came from both the interfacial and bulk polarization mechanisms, and the contributions from different mechanisms varied with temperature and film thickness. The interfacial dielectric mechanisms showed the charge transport dependence and were affected by the external DC bias.

Most researches about virtual machine tool are emphasized on simulations of machine motion and machining process for single machine. In this paper,a virtual simulation system for remote collaborative surface machining is developed. The motion command of machine tool is generated by an interpolator,which can derive synchronized motion commands according to feedrate. Thus,the system can estimate the machining time. For universal assembly of five-axis virtual machine tool,it is based on the D-H notation representation and machining constraints consideration. The remote collaborative virtual manufacturing system based on the CORBA technology is proposed in this paper. It demonstrated that the developed virtual machine tool can be used to verify and simulate the machining process for the collaboration of the surface design and manufacturing team.

为了调查在校大学生干眼情况,探讨影响大学生干眼的相关因素,为预防和治疗大学生干眼提供一定的理论依据.采用横断面调查方式,随机收集1307名在校大学生的基本信息、生活习惯、用眼习惯及眼表疾病指数(OSDI)量表,进一步检查有干眼相关症状的大学生,并进行干眼诊断.通过单因素分析(χ^(2)检验)筛选影响因素,对差异有统计学意义的影响因素进行二元Logistic回归分析.结果表明:性别、入睡时间点、睡眠时间、饮食、运动及每日电子产品的使用时间等因素均对在校大学生的干眼有影响,其中,入睡时间点较迟的熬夜和长时间使用电子产品是大学生患干眼的主要影响因素.
