从画僧的参融看新安画派作品的视觉呈现因素

以渐江为代表的新安画派,在禅学、儒学、道学三学合一的明清人文环境下,怀着对故国的眷恋之意,在新安之地,师法于徽州的山岳自然,创造出有别于明清摹古之风的具有减笔之风、线面之风、徽刻之风、云林之风的新的视觉呈现方式。这既有别于"四王"作品的视觉表达,又在倪云林画风的基础上,经行了视觉呈现方式的改造;既包含了中国绘画的高古之意,又融合了徽州版画的线性表达;也没有脱离儒家风范和禅家的入定思想。由此,以画僧渐江为代表的新安画派给中国画史带来了声名彰著的精彩一章。

诗画本一律 天工与清新——诗画参融与北宋士人、文人的审美发生

北宋时期的题画诗与诗意画呈现出明显的诗画参融整合现象,这一现象与北宋士人、文人的审美发生密切相关。本文从"六艺"之外的"画者"之地位流变,参融整合:融合视觉与想象之长的题画诗,诗画共同的表达主题、情感依附与审美趣味三方面来阐释这一问题。

高校思政课“转融参双”混合教学模式研究

高校思想政治理论课的“转融参双”混合教学,从本质上讲是一种教学方法,也是一种思维方式,内涵以问题和逻辑为导向、以多学科元素融入为手段、以学生与老师互动为中心、以多形式上课为载体的严密逻辑过程。在实施过程中,要遵循“形”转“意”不转、多学科知识为“言马”服务、调动学生“全身”参与的教学原则和要求。从精心设计“问题导向”和“逻辑导向”的教学过程、持续优化高校思政课教师队伍、切实健全完善思政课教学的保障机制等方面,构建“转融参双”教学模式的组织保障。

“如何活”难题的审美纾解

在其主体性实践哲学中,李泽厚对“如何活”难题深表关切,于是将人性能力的充分发展当作纾解这一难题的选择方案。人性能力作为人性的至要决定因素,基于文化心理结构,涉及认知、道德与审美三个维度。人性能力的提升,有赖于四重性审美参融,取决于以美启真、以美储善、以美立命与以度创美这四种动态关联行为。人性能力的充分发展,自当成就人类主体性,助推人性的完满实现,上达人之成人所能取得的最高成就。

Early warning of rock mass instability based on multi-field coupling analysis and microseismic monitoring

In order to overcome the limitation that rock mass instability warnings are caused by a lack of deep consideration of the inherent mechanism of disaster formation, early warning signs of rock mass instability were detected and multi-field coupling was analyzed. A multi-field coupling model of a damaged rock mass was established. The relationship between microseismic activity parameters and rock mass stability was analyzed, and a multi-parameter early warning index system was established and its solution program was compiled. Based on the D-S data fusion theory,an early warning model of rock mass instability combining multi-field coupling analysis and microseismic monitoring was constructed. Taking an underground mine stope as an object, the multi-field coupling model and its solution program were used to analyze mining response characteristics. The seismic field data were used to verify the accuracy of the multi-field coupling analysis. The early warning model was used to predict the instability of stope rock mass,and the early warning result is consistent with a real-world scenario.

Effects of melt spinning process parameters and wheel surface quality on production of 6060 aluminum alloy powders and ribbons

The aim of this study is to investigate the surface quality of the melt spinning wheel, which was changed from smooth type to textured structure, to atomize liquid metal to form powders. The effects of melt spinning process parameters like wheel speed, gas ejection pressure, molten metal temperature, nozzle–wheel gap and wheel surface quality on the morphological and microstructural features of 6060 aluminum alloy powders and ribbons were investigated. It was observed that ribbon type material was obtained with the smooth wheel and the powder was produced with textured type. The sizes of produced ribbons with smooth surface wheel varied in the range of 30-170 μm in thickness, 4-8 mm in width, and 0.5-1 m in length. The average powder size of the powders manufactured using the textured wheel was in the range of 161-274 μm, depending on the process parameters.Increasing the wheel speed, melt temperature and decreasing gas ejection pressure, nozzle-wheel gap resulted in the decrease of both ribbon thickness and powder size. The microstructures of the powders and ribbons were the equiaxed cellular type, and the average grain sizes diminished with decreasing the ribbon thickness and powder size. The maximum cooling rates were 2.00×10^5 and 1.26×10^4 K/s for the ribbon with thickness of 30 μm and for the powder with size of 87 μm, respectively.

Air-void parameters measurement of fresh concrete and hardened concrete

Air content, spacing factor and specific surface of fresh concrete and hardened concrete with different air contents, slumps and mineral admixtures (fly ash, slag, fly ash + slag, fly ash + slag + silica fume composite) were studied by the air-void analyzer (AVA) method and the microscopical method. The correlations between the test results obtained from different methods were analyzed. The results show that, there is a close correlation of air content and spacing factor between the fresh concrete and the hardened concrete, but the specific surface correlation is weak. The air content of concrete measured by the AVA method is smaller than that of the pressure method and the microscopical method, because AVA device captures only the air voids with the size smaller than 3 mm. Spacing factor of the fresh concrete measured by the AVA method is greater than that of the hardened concrete measured by the microscopical method, while the specific surface is smaller. When the criterion of 4%-7% air content measured by the pressure method and microscopical method is acceptable for concrete freezing-thawing (F-T) durability in cold weather, the air content measured by the AVA method should be 2.4%-4.6%. For the concrete F-T durability, when the criterion of the spacing factor measured by the microscopical method is 300 μm, the spacing factor measured by the AVA method should be 360 μm.

Restricted normal mixture QMLE for non-stationary TGARCH(1,1) models

The threshold GARCH(TGARCH)models have been very useful for analyzing asymmetric volatilities arising from financial time series.Most research on TGARCH has been directed to the stationary case.This paper studies the estimation of non-stationary first order TGARCH models.Restricted normal mixture quasi-maximum likelihood estimation(NM-QMLE)for non-stationary TGARCH models is proposed in the sense that we estimate the other parameters with any fixed location parameter.We show that the proposed estimators(except location parameter)are consistent and asymptotically normal under mild regular conditions.The impact of relative leptokursis and skewness of the innovations’distribution and quasi-likelihood distributions on the asymptotic efficiency has been discussed.Numerical results lend further support to our theoretical results.Finally,an illustrated real example is presented.
