岁寒三友结合瓷道所传达的人文精神

瓷,自商代开始出现原始瓷以来,就包含着金木水火土等成分。金土:瓷在烧成之前是先用泥土成型,泥土中含有铁、铅等金属矿物质,这就包含着金与土;可以说瓷在成型过程中就需要水的调和使得泥土变软便于成型,这就是水;由泥成型的坯胎变成瓷木柴和火是必不可少的,这就是木和火,可见五行在瓷中缺一不可以。五行则是道,水则最是道的最好诠释。岁寒三友中的松、竹、梅有着与人紧密相连的人文精神,本文就岁寒三友结合瓷道所传达的人文精神进行略轮。

景德镇粉彩轧道瓷的发展与展望

粉彩轧道瓷是景德镇独特而古老的陶瓷艺术类型。本文简要介绍粉彩轧道瓷的历程及工艺发展。当代粉彩轧道瓷在传承与发展方面均面临严峻考验,需要在政府加大保护力度及宣传、粉彩轧道装饰材料无铅化等方面采取必要途径。

瓷器上的中国“道”

胡塞尔认为意识具有多义性,即"意识是作为间向性的体验,体验具有对对象的指向性"。很显然,意识除了抽象的理论思维外,还同实践相关联,所以意识的意向性同经验主体的实践经验不可分离。中国瓷器,作为艺术体验的指向对象,其精美绝伦的主体实践经验,在人类意向性文明体验中形成了独特的艺术文化价值史。瓷器,不仅仅改善了民众生活,更主要的是从实用到审美的意向性文明体验,建构了中国瓷器生活;这种艺术创造过程,也是文化精粹的人生表现过程;这种精粹人生,可以用瓷"道"来概括。瓷,是形;道,是意。这种形意相生的"道"源文化,与中国传统文化的母体精神是密不可分的。从中国瓷器所蕴含的"道"意元素,即素朴、虚静、神妙、自然几个方面,分析和关注器型上凸显的哲学文化元素,剖析瓷器中所包含的文化特征——天真、重生恶死、乘物以游心、圆柔等。

Flow and Leakage Characteristics in Sealing Chamber of a Variable Geometry Hypersonic Inlet

When the variable geometry hypersonic inlet is sealed with ceramic wafers,the cavity flows inside the sealing chamber can be affected by the boundary layer near the side wall.To study the influence of the boundary layer thickness near the side wall on the flow and leakage characteristics in sealing chamber,the numerical calculation of the cavity flow in the sealing chamber under different inflow boundary layer thicknesses is carried out.The results show that three-dimensional cavity flow structures are close to being asymmetric,and the entrance pressure of the leakage path can also be affected by asymmetry;with the increase of the thickness of the boundary layer,the pressure at the cavity floor and the seal entrance decreases.Finally,the existing leakage prediction model is modified according to the distribution rule of the cavity floor and the flow properties in the leakage path.
