任何一个科学的名词术语,都有明确的定义,它给人以概念,作为研究问题的基础;而定义所规定的意义,又是从生产实践和科学研究的需要出发,并符合人们的一般逻辑思维。中心偏定义也应符合这样的条件。但它在某些方面有所欠缺,所以有研究的必要。一、中心偏名字的由来及演变德国国家作准(DIN3140)最早以球面单透镜的光轴对于机械轴的平行偏移量C来定义中心编(Zentrierfehler),他们对光学系统中各单透镜的偏心也是这样定义的,如图Ia、b,图b中的C_1、C_2、C_3等表示各单透镜对系统轴的偏心。苏联五十年
Any scientific terminology, have a clear definition, it gives the concept of as the basis for the study of the problem; and the definition of the meaning of the provisions, but also from the production practice and scientific research needs, and in line with the general logic of people thinking. Center bias should also meet such conditions. But it is lacking in some aspects, so there is a need for research. First, the center of the origin and evolution of the name of the German national standards (DIN3140) The earliest spherical single-lens optical axis parallel to the mechanical axis offset C to define the center of the series (Zentrierfehler), their optical system of the single lens eccentricity Also defined as shown in Figure Ia, b, Figure b C_1, C_2, C_3 and so on that the single lens on the system axis eccentricity.
