一幅画不仪是个色彩表面,它是一个多层结构的,复杂的、三度空间的物体。以一张地质图作比较,除了地层的不同厚度和构成,也取决于地表最终的变化。构成一幅画最起码要有一个基底;比如:木板或画布。这块平面就作为底子和涂层的中介。涂层就是用蜡、油或蛋去调合颜料粉所形成的溶剂。历史上,一些优质材料用于做画的基底,象铜、石头、纸、皮革、塑料等等。但最常用的是木板和 A picture is not a color surface, it is a multi-layer structure, complex, three-dimensional space objects. A comparison of a geological map, with the exception of the different thickness and composition of the formation, also depends on the final change in the surface. The composition of a painting should at least have a base; for example: wood or canvas. This plane serves as the foundation and coating agent. Coating is the use of wax, oil or egg to paint the pigment formed by the solvent. Historically, some high-quality materials were used to make painted substrates, like copper, stone, paper, leather, plastic, and so on. But the most commonly used is wood and
