In chapter one, it compared letters with pictures and showed the importance of observation. In chapter two, it introduced the structure of human eyes and the course of vision. Chapter three introduced the basic key element of vision and the main theories of studying in vision aesthesia. In chapter four, it analyzed the principle of understanding the meaning of a figure according to the theory before, and analyzed the law of aesthetic. Then it explained how people feel the three-dimensional form and the movement, which have offered the theoretical foundation for creating more vivid image. It expounded the purpose and meaning of judging a visual figure in the fifth chapter, and introduced three general standards. It showed a method of judging the figure from different points of view in an example. Summarize to the full text finally, it point out the correct observation of vision image is one of the main ways for people's study, proposed the weak point of this text.

本文在第一章对文字与形象两类视觉信息进行了比较，提出了掌握形象观察方法的重要性；接着在第二章简单介绍了人眼的构造和视觉成像的过程；第三章分别介绍了视觉感知的基本要素和目前研究视觉的主要理论；在第四章，根据感知理论重点分析了人们识别、理解图形意义的原则，并由此归纳总结了形式美感产生的规律，提出了创造生动的视觉形象和构筑立体形象的规则和方法；第五章则阐述了对视觉形象进行评价的目的和意义，介绍了评价的三大普遍标准，针对人工形象提出了一套评价系统，并通过一个实例来说明评价系统的使用过程；最后对全文做出总结，指出正确的认识视觉形象是人们学习的主要途径之一，并提出了本文的不足之处。

The dose enhancement effects and decreasing effects caused by material inhomogeneity were studied quantitatively with a parameter named Dose Perturbation Factor, which was the ratio of the dose at a point in the heterogeneous phantom to the dose of the same spatial location point in the homogeneous phantom. It was showed that the degrees of the dose enhancement or decreasing depended on the energy of radiation, field sizes of the beamlets and compositions of the media. The dose perturbation for high energy X rays is greater than that for low energy X rays. At the same energy condition, the dose perturbation decreased when the field size increased. And the relationship between them was not linear.

模拟结果表明：在小射野情况下，异质组织界面处出现了较大的剂量跃变，剂量扰动效应的强弱程度取决于射线的能量、射野的大小和模体介质的不同等多种因素，高能X射线条件下的剂量扰动效应大于低能X射线条件下的剂量扰动；在入射X射线能量相同的条件下，剂量扰动效应随射野尺寸的减小而增强，并呈现一种非线性关系。
