        摘要：Interest in organic nonlinear optical materials has grown tremendously in recent years. Some polarable organic molecules exhibit larger second order susceptibility, but only small amount materials show bulk susceptibility due to the limitation of crystalline symmetry. Poled polymeric technology can make a statistical noncentrosymmetric environment. After a brief introduction to the principles of organic nonlinear optics and the procedures of poling, the progresses of polymeric second order nonlinear optical materials are reviewed. In addition, the researches of third order nonlinear optical effect of polymer are reviewed, too.

        摘要：Generally speaking the relationship between electrical conductivity σ and temperature T for the Polymer compositions filled with conductive fillers can be divided into three classes, i. e. NTC, LPTC and HPTC.The compositions with HPTC have many applications. The paper reviewed the development of study on σ/T relationship, and discussed some factors which influnced it.
