The meaning of forgey in various legislation comprises visible forgery and invisible forgery.Visible forgery is the man,who has no right to make documents,personates other's nominal and makes documents.Invisible forgery is the man,who has right to make documents,makes false documents.The difference between them is whether the nominal person and manufacturer are identical.The purpose of penalizing invisible forgery is it infringes upon documents' evidence.

对于伪造，我国学说和司法实践较为关注无制作权限人的非法制作文书的行为，对有制作权限者所从事的制作内容虚伪文书行为却重视不够，但从伪造文书罪的保护法益来看，无形伪造的行为也侵犯了文书的社会信用，有必要加以刑事处罚；另外，在理论上和实践中区分两种不同情形的伪造，有利于明确刑事立法的宗旨，推动立法的改进和理论研讨的深入。

Fluorescence occurs when ultraviolet radiation from just outside the visible spectrum is absorbed and re-emitted as visible light,thus increasing the total amount of light refected from a surface.Fluorescent brightening agents are commonly added to paper and boards to make them brighten and whiter and to increase the possible density range that can be achieved when printing on them.
