The number and intensity of peaks of the thermoluminescent cutves are obviously related to stages of gold mineralization:the curve of the early barren quartz shows nearly Symmetric pattern; that of the major stage auriferous quartz is of multimodal type; the curve of the late quartz, low in gold, is marked by unimodal--bimodal type with rather intense luminescence.

石英热发光曲线的发光峰的数量和强度与金成矿阶段有着明显的关系：早期成矿阶段结晶的基本不含金石英，热发光曲线常为近对称的单峰型，发光强度较大；主成矿阶段形成的含金石英，热发光曲线为多峰型，常具最大的发光强度；晚期成矿阶段生成的含金性较差的右英，热发光曲线呈单峰-双峰型，发光强度亦较大。

Methods. PSF 1000 analyzer was used to measure retinal image quality for eye of 26 subjects (spherical ranged from –3.00 ~-6.00Ds, astigmatism ranged from –0.75~-3.00Dc) fitted with three forms of full correction in random order : unaided eye, with rigid gas permeable contact lenses and toric soft contact lenses.
