  image
Using these monomial bases we prove that the image of the transfer for a general linear group over a finite field is a principal ideal in the ring of invariants.
      
It is injective and its image coincides with the set ofEx-fixed points inI.
      
A pattern for an element of a Weyl group is its image under a combinatorially defined map to a subgroup generated by reflections.
      
The Discrete Wavelet Transform (DWT) is of considerable practical use in image and signal processing applications.
      
Among all image transforms, the classical (Euclidean) Fourier transform has had the widest range of applications in image processing.

This paper deals theoretically with the influences of various kinds of mutual co-herence function and the degree of coherence on the distribution of straight-edge generated image field. Indicating the close connections between the illuminating con-dition and image formation, we thus obtain the reliable method to select the optimal illuminating condition. Based on our theoretical calculation on optical system with aberration, it is shown that the radial intensity distribution of the straight-edge generated imagery...

Several patterns of silver halide grain array in emulsion layers are designed and a method of computer simulation of granularity measurement is used to analyse the image layers. These image layers are obtained from the photographic layers with various patterns of grain arrays after exposure and development. The variations of granularity with relative densities are analysed. In the simulating measurements of granularities for the patterned grain layers, it is found that a minor variation in sampling aperture...

Several patterns of silver halide grain array in emulsion layers are designed and a method of computer simulation of granularity measurement is used to analyse the image layers. These image layers are obtained from the photographic layers with various patterns of grain arrays after exposure and development. The variations of granularity with relative densities are analysed. In the simulating measurements of granularities for the patterned grain layers, it is found that a minor variation in sampling aperture size causes a considerable fluctuation of the granularity values measured. That differs from that of the conventional photographic layers in which grains are randomly distributed. It may be predicted that the shape of sampling aperture and its orientation over the samples will have an appreciable influence on the granularity measurement. A circular aperture, therefore, is supposed to be more appropriate.

在本工作中,设计了几种照相层中卤化银颗粒有序排列的图案,并采用计算机模拟测量颗粒度的方法分析了颗粒按各种图案排列的照相层在曝光和显影之后的影象层的颗粒度随密度的变化,从而确定较佳的颗粒排列的图案。在对颗粒有序排列的照相层进行颗粒度模拟测量的时候发现:与颗粒随机排列照相层的颗粒度测量不同,方形采样孔尺寸的微小变化会引起颗粒度测量值颇大的波动。可以预料,方形采样孔在试样上的取向对测量结果也会有影响。因此,圆形采样孔可能比较适合于用来测量有序卤化银照相层的颗粒度。

Angular distribution Auger microscopy is reviewed as a new develepment in Auger electron spectroscopy. Measurements and display of the complete angular distributionof Auger electrons give rise to the image of near-surface atoms,which afford a technique for the characterization of the atom, molecular structure of surfaces of the samples. A theory is put forward accordingly to explain the formation of the image with the "reflection" mechanism of near-surface atoms by Auger emission from atoms deeper in solid. Theoretical simulations of Auger electron angular distributions are in close agreement with experimental results, as illustrated by taking Pt and I as examples. The establishment of angular distribution Auger microscopy has been a great contribution to Auger electron spectroscopy.

综述了俄歇电子能谱的新进展──角分布俄歇显微术。测量和展示俄歇电子的全角分布可给出浅表面原子的影象,借此可对样品表面原子、分子结构进行表征。理论认为这种原子形象是浅表面原子受较深层原子发射俄歇电子映照而成的,以Pt、I2为例,用相应理论教学模式模拟,所得结果和实验结果极相符合。角分布俄歇显微术在实践和理论上将俄歇电子能谱向前推进了一步。
