Angular distributions of sputtered atoms and the phenamenon of element locally rich relative to microtopographic feature(ELR-MTF) of sputtered target surface have been investigated for Cu-37 at%Ag alloys by means of RBS,SEM and EPMA measurements.In this paper,emphasis will be put on the correlation between surface topography caused by Ar+ ion bombardment with different doses and angular distribution of sputtered atoms ejecting from various micro-zones at topographical surface during sputtering.The experiment...

Angular distributions of sputtered atoms and the phenamenon of element locally rich relative to microtopographic feature(ELR-MTF) of sputtered target surface have been investigated for Cu-37 at%Ag alloys by means of RBS,SEM and EPMA measurements.In this paper,emphasis will be put on the correlation between surface topography caused by Ar+ ion bombardment with different doses and angular distribution of sputtered atoms ejecting from various micro-zones at topographical surface during sputtering.The experiment result was explained with the so-called ELR-MTF model which can qualitatively interpret the shape of the angular distributions and the variation of the preferential sputtering curves.

The studies of transfer characteristic and modulation transfer function (MTF) of human visual system are introduced Several MTF models are analyzed Barten model and compound model with band pass characteristic are more suitable for human eyes transfer characteristic, and are more superior to traditional exponent model and Gauss model which have low pass characteristics On the basis of these, the comparison between the theoretical value and experimental value shows that both of band bass models are according with human eyes' experimental data Barten model is simple and compound model is concerned with the pupil of human eye, field angle, quantum efficiency, integrating time and so on Compound model is a better model that can roundly reflect the human eyes' transfer characteristic

介绍了国内外对人眼视觉特性及其调制传递函数的研究 ,对几种典型的人眼视觉模型进行了分析。较之以往采用的具有低通特性的指数型和高斯型 ,及具有带通特性的Barten模型和复合模型更符合人眼视觉传递特性。在此基础上将两种带通模型和国内外一些典型的试验数据进行了比较研究 ,得出 :Barten模型参数简单 ,计算方便 ,但实用的范围较复合模型小。复合模型综合考虑了人眼瞳孔、显示器亮度、视场角、量子效率、积分时间等因素的影响 ,是一种更全面的反映人眼传递特性的视觉模型
