彩色石版画印刷术

Chinese prints, after a thousand years of development, from woodcuts to the copper engraving, lithographs, from monochrome printing to color overprint by a single print religious literature to develop prints, prints Hua Pu, in areas such as print New Year by the text attached to the Illustrations to be relatively independent of the arts, has made brilliant achievements of ancient Chinese art has become an important part, but also any country in the world and prints pair with more than.

和造纸、印刷术一样，版画艺术的故乡也在中国。版画是在绘画艺术和雕版印刷术的基础上发展起来的，它始于隋，行于唐，扩于宋，精于明，衰于清。经过一千多年的发展，中国版画由木刻版画到铜版画、石版画，由单色印刷到彩色套印，由单一的宗教版画拓展到文学版画、画谱版画、年节版画等领域，由依附于文字的插图到成为相对独立的艺术，取得了辉煌的成就，成为中国古代美术的重要组成部分，而且可以和世界任何一个国家的版画相媲比。

Third, based on the example of over proof on-load loss in 180MVA/220kV power transformer, the eddy loss in winding is analyzed with the leakage flux element software. Some conclusions with practical use are given. In order to reduce the load loss, primarily we should reduce radial leakage flux of transformer possibily.

运用漏磁场分析软件，以180MVA/220kV电力变压器负载损耗超标为例，进行详细分析，提出有工程实用价值的结论：降低变压器负载损耗，从根本上应尽可能减少变压器辐向漏磁。
