Inclined LED array and flat bottomreflector for large-sized backlight system was proposed to obtain high brightness uniformity.
为获得非常均匀的高亮度，建议采用倾斜led阵列和平底反射器大型背光系统。

The data of NT62-2 seismic line of western Nankai Trough are reprocessed, and the character of the distribution of Bottom simulating reflector (BSR) is emphasized.
On the base of relative data of the maximal deformation, studied the factors that effect the deformation of reflector surface of small telescope with bottom support.
