In the paper, the electrode system of the original TL/TSC measurement instrument is improved, which greatly facilitates sample exchange and increased liquid nitrogen's running and cooling speed. Through long time and repeated practice we finally find an effective method to prepare films. We've synthesized a new kind of organic photo-refraction material nitryl azobenzene grafting PVK and characterized it with IR spectra. We've also synthesized 5OCB and found the optimal mass ratio of PVK/5OCB/C60-49.8:50:0.2, and given the two-beam coupling testing result.

Latest research indicates that,if eating a great deal of undone eggs for a long time,antibiotin protein in undone egg white can integrate with biotin internal the body as a sort of steady compound,making biotin can't be absorbed by intestinal wall and leading to energy ennui,muscle ache,hair falling off,skin inflamation,appetite letdown,weight droping and so on.When eggs pass through the intestinal tract,it's easy to zymolysis and transformation,sometimes it may appear nitroso compound,which has the function of causing cancer.
