The paper expounds the principle and advantages of disinfection by UV-C radiation, introduces the relative technologies and products at home and abroad, designs elliptic and parabolic cylindroid lampshade of bank paper disinfection apparatus with \!equal path surface\" principle.

According to the theoretical analysis on two-photon microfabrication of free-radical photopolymer,the relationship between excitation power and resolution of fabrication system is discussed based on the concept of isocandela diagram.

After theoretically calculating the opto\|electrical signal, it is got that it is necessary to maintain the equal optical path between measuring beam and reference beam in mearsuring horizontal and vertical vibration table.
