光密度

The solid immersion lens can be used into an optical storage system It provides the high NA of the system and uses the evanescent wave to produce extremely small optical spots Two proposals about a SIL are given out here The first one is that the protecting layer of the recording layer can be used as one part of the hemi spherical SIL So the recording layer is not polluted The second one is that a SIL can be used at same time in a double layers storage The first recording layer is used a...

固体浸没透镜用于光存储光学系统增大了光学头物镜的数值孔径，利用近场倏逝波读写，减小了光斑的直径，提高了存储密度。文中建议：(1)将半球SIL分割成两部分，其中一部分由存储媒质的保护层充当，避免直接污染记录层；(2 )在半球SIL单层读写的基础上，再将第一层记录媒质作为SIL的一部分形成超半球齐明SIL ，以实现双层存储。并对此时的近场进行了解析分折

The intensity formula shows that the light intensity at any point of a curved surface is not only related to the amplitude at the point, but also related to the included angle between the Poynting vector and the direction of the local differential surface element.

This dissertation was designed to study heteto-phase grafting polymerization of vinyl acetate , maleic anhydride and VAC/MAH binary monomer system, irrespectively, with low density polyethylene film as substrate and benzophenone as photoinitiator. The purpose is to develop new and more effective methods to modify the surface and buck properties of polyolefines by studying the grafting mechanism of the system and exploring the characteristics of the grafting process.

AB glue and polyethylene were disperse systems, in which Rhoda-mine 6G, lactoflavin and 2, 9-dimethyl, 4, 4-diphenyl, 1, 10-phenanthroline were dispersed with different concentrations. A heat-melt method was used to prepare organic light transform films. Excited at 460nm and 500nm, fluorescence spectrums of these films were measured.

Results One case with infantile onset had macrocephaly. The CT scan and MRI showedprominent low-density white matter throughout the cerebral hemispheres. MRI showed prominent also increased T2 signal in the periventricular whitematter. Another patient had an onset at school-age. The CT scan demonstrated brain atrophy. Histological examination on brain biopsy revealed diffuse demyelination and fibrous gliosis.
