RUNOFF VARIATION IN MIDSTREAM HEI RIVER, NORTHWEST CHINA: CHARACTERISTICS AND DRIVING FACTORS ANALYSIS


Thermal relaxation of optical nonlinearity in poled glasses

The thermal relaxation of second order optical nonlinearity in subsurface layer of a poled soda-lime silicate glass was studied.It is shown that the glass annealing below glass transition temperature leads to full relaxation of the nonlinearity.At ultra max dog shampoo the same time, the measurements of thermostimulated depolarization current demon
