The spatial structure of relief can be a three-dimensional form or a plane form; It can not only be attached to a certain carrier, but also exist relatively independently. Generally speaking, in order to meet the viewing or decoration needs of specific viewpoints, the prominent feature of relief relative to round sculpture is the two-dimensional or plane characteristics after shape compression. The difference between relief and round sculpture lies in its relative planarity and three-dimensional.

它的空间形态是介于绘画所具有的二维虚拟空间与圆雕所具有的三维实体空间之间的所谓压缩空间。压缩空间限定了浮雕空间的自由发展，在平面背景的依托下，圆雕的实体感减弱了，而更多地采纳和利用绘画及透视学中的虚拟与错觉来达到表现目的。与圆雕相比，浮雕多按照绘画原则来处理空间和形体关系。

Its spatial form is the so-called compressed space between the two-dimensional virtual space of painting and the three-dimensional solid space of round sculpture. Compressed space limits the free development of relief space. Relying on the plane background, the sense of entity of round sculpture is weakened, and more virtual and illusion in painting and perspective are adopted and used to achieve the purpose of expression. Compared with round sculpture, relief mostly deals with the relationship between space and form according to the principles of painting.

但是，在反映审美意象这一中心追求上，浮雕和圆雕是完全一致，不同的手法形式所显示的只是某种外表特征。作为雕塑艺术的种类之一，浮雕表现出雕塑艺术的一般特征，即它的审美效果不但诉诸视觉而且涉及触觉。

However, in reflecting the central pursuit of aesthetic image, relief and round sculpture are completely consistent, and different techniques and forms show only some appearance characteristics. As one of the types of sculpture art, relief first shows the general characteristics of sculpture art, that is, its aesthetic effect not only appeals to vision, but also involves touch.

与此同时，它又能很好地发挥绘画艺术在构图、题材和空间处理等方面的优势，表现圆雕所不能表现的内容和对象，譬如事件和人物的背景与环境、叙事情节的连续与转折、不同时空视角的自由切换、复杂多样事物的穿插和重叠等。

At the same time, it can give full play to the advantages of painting art in composition, theme and space processing, and show the contents and objects that the round sculpture cannot show, such as the background and environment of events and characters, the continuity and turning of narrative plot, the free switching of different time and space perspectives, the insertion and overlap of complex and diverse things, etc.

平面上的雕凿与塑造，使浮雕可以综合雕塑与绘画的技术优势，保持手法上的多样性和多样化。二维空间中的透视缩减，陪衬主体形象的背景刻画或虚拟，使浮雕的塑造语言比之其它雕塑尤其是圆雕，具有更强的叙事性同时也不失一般雕塑的表现性。

The carving and shaping on the plane can integrate the technical advantages of sculpture and painting, and maintain the diversity and diversification of techniques. The reduction of perspective in two-dimensional space and the background depiction or virtualization of the main image make the modeling language of relief more narrative than other sculptures, especially round sculptures, without losing the expressiveness of general sculptures.
