    The traditional objective evaluation method is not the same as the research of product's sound quality because of it's ignoring the subjective perception of human. But the general method of evaluation of sound quality which is carried out with people on-line has the limitation of efficiency, cost, time and so forth, so it is necessary to establish objective evaluation method which is the foundation of designing sound quality.
    传统的声信号的客观评价由于没有充分考虑人对声音的主观感受,因此不适用于产品的声质量研究,而常用的由人直接去听测的声质量主观评价方法存在效率、滞后性等局限性,因此声质量的客观评价方法成为必要,并且这种方法是进行声质量设计的基础。

A blue imaging technology for medical radiography has been developed in this institute. It was proved superior to ordinary B/W radiographic film in that the X-ray dose can be reduced to 1/5 and all the silver can be recovered. Image assessment has been done in this work with the determination of the speed, gamma, resolving power, MTF and noise level of the blue dye image and in comparison with that of the silver image.

A blue imaging technology for medical radiography has been developed in this institute. It was proved superior to ordinary B/W radiographic film in that the X-ray dose can be reduced to 1/5 and all the silver can be recovered. Image assessment has been done in this work with the determination of the speed, gamma, resolving power, MTF and noise level of the blue dye image and in comparison with that of the silver image. B/W radiographic films with on-eside emulsion coating were used in order to eliminate the complication imposed by the crossover effect in the MTF and noise level determinations. The samples were exposed with light and processed to B/W and blue images respectively. The results showed that the speed, gamma, Dmax and the low spatial frequency response of the MTF of the blue image are much improved compared with that of the B/W image, although the fog levels are a little bit higher. The resolving power of the blue image is almost the same of the B/W image. Both the macro- and micronoise are higher for the dye image, but no extra large-scale non-uniformity was introduced in the dye-image formation. The high frequency response of the MTF got poorer in forming the dye image. Summing up all these characteristics, the blue imaging technology is still favourable for medical radiography. In this case the useful imaging frequency range is extended to only about 10 1ps/mm, and the quantum mottle becomes the main source of noise. The-results obtained in this work are in accordance with that of the subjective evaluation in clinical diagnosis.

本文对黑白胶片经过特殊的蓝色成象工艺加工后形成的影象的质量进行了客观评价。结果表明,用蓝色成象工艺,感光度、特性曲线直线部分的斜率γ、最大密度及调制传递函数在低空间频率的响应等,均较黑白影象有不同程度的改善和提高;分辨率基本相同;粒度有些增高;调制传递函数的高频响应变坏。这种成象工艺用于对空间频率上限要求不高的一些成象体系,如X射线照象是有利的。这与临床诊断的主观评价的结果一致。

The method of objective measurements combined with subjective evaluation is adopted to study the influence of highway traffic noise on human beings. Threshold values of disturbing highway traffic noise are obtained, and the relation between the objective and the subjective rating scales of the highway traffic noise is analysed. The research results show that the statistical sound level L10 is more suitable than the equiv-alent sound level Leq for human subjective rating of the highway traffic noise.
