本文根据对建板的树种鉴定和理化性能,距今年龄测定,并通过现场考察,确定了建板是由德昌杉木因地壳局部变动埋没后发生化学组成变化,具有强耐腐力的名贵木材.提出了德昌一带是德昌杉木的古老自然分布区.建板是一种阴沉木.此种阴沉本色泽美观,芳香致密,经久耐腐,从前人们用以制作名贵的棺木.德昌称棺木为大板,因主产四川德昌县,德昌原属西昌县,西昌原名建昌,所以把产于德昌一带的这种阴沉木叫做建板,又称困杉、陈乔、阴沉、香杉花板、阴沉香杉板.数百年前,我国劳动人民就开始了对建板的发掘利用.据西昌县志记载:(?)‘由数千年之杉林,因地壳变动,埋没土中,经水冲出制成者,其芳香致密经久无与伦比,分红油紫油两种’.‘初由土中挖出时,有直径丈余,长二三十丈者.有边材腐朽仅剩心材者,有并边材亦完好者,观其状况可知其年之先后也.’‘以其香气剧烈,油汁丰富,且甚耐久故也,此种香杉花板可耐七八百年,因县属坟墓有明洪武时埋没迄今完好者.’‘山崩料出……然一山厂中,每一料出或数株并出,其位置方向,往往纵横斜亘.’‘此种香杉花板,县人运往各大都会售卖,价值最昂.’(?)由于建板的特殊名质,建板的考证早被国内外科学工作者所关注,曾作一些调查研究,对成因和特性有各种推测.为了查明建板是何种树种,成因、特性,? Based on the identification and physical and chemical properties of the tree species, dating back to the present age, and through on-site investigation, it was confirmed that the building of the tree was caused by the chemical composition change of the Dachang fir after local changes in the crust, and the precious wood with strong decay resistance It is proposed that the area of ​​Johnson in Dechang is the ancient natural distribution area of ​​Dichang fir, and the building board is a gloomy wood, which is beautiful in appearance and dense in color, fragrant and dense, durable and anticorrosive, and used to make expensive coffin. The coffin is a large plate, because the main production of Sichuan Changchang County, Johnson’s original Xichang County, Xichang formerly known as Jianchang, so produced in Durham area of ​​this gloomy wood called building board, also known as storm fir, Joe Chen, gloomy Hundreds of years ago, our working people began to explore the use of building board. According to Xichang County Chronicles: (?) ’Thousands of years of fir forest, due to changes in the crust, buried Soil, washed out by the water, the aromatic dense durable unparalleled dividends oil purple two ’.’ At the beginning of excavation from the earth, there are more than ten feet in diameter, long twenty or thirty husband. Only the left heartwood material, and sapwood are also intact, view the status of its year after another can also see. Aroma aroma, oil rich, and very durable and therefore, such a fragrant cedar board can withstand seven or eight years, because the county is still Hongwu buried so far intact. , Each expected or a few strains and out of the direction of their position, often criss-cross. ’’ This Hongshanban, the county shipped to the metropolis for sale, the most expensive. ’(?) Due to the special building board Quality, building board research has long been the concern of scientists at home and abroad, has made some investigations and studies, the causes and characteristics of a variety of speculation.In order to identify the building board is what kind of tree, causes, characteristics?

电视照明是电视艺术领域的一个艺术分支,是用光绘画、用光造型、用光表达空间和时间的一门艺术。从技术层面上讲,电视照明为电视画面拍摄提供必需的基本光亮度,是影响电视图像质量的重要因素之一,决定着画面的清晰度、色调和层次等。而从艺术层面上讲,电视照明不仅可以美化电视画面、丰富视觉效果,还可以烘托情节气氛,揭示及刻画人物心理,进而突出电视艺术主题和内涵。近年来,随着高新科技的日益发展,电视照明技术也日趋走
