1) It is slower that this kind of excitation catoptric that carry Gao appears, what in resembling evoking a process in the gender, see in that way.

2) Catoptric apparatus contains two kinds of pigment, namely distal and proximal pigment.

3) The iterative formula of measurement of optical lens decentration is deduced on the basis of self-collimation catoptric methods.

4) The reason for the different phenomenons of Newtons ring under transmission light and catoptric light is analysed.

5) The mirror glass carrier has the light refracted and affects the catoptric imaging of the light onthe reflection plane.

6) The mirror glass carrier light refracted and affects the catoptric imaging light onthe reflection plane.
