不辐射的

The computation analysis indicates that increasing the aperture of the concave focusing transducer, decreasing it's geometric focal length or raising it's central working frequency can improve the transverse and axial resolutions of the system simultaneously, but changing the dividing proportion of the transducer affects the two kinds of resolution differently. On compromisingly considering several factors including the exciting mode, the focusing ability and the radiation force effect, the concave focusing transducer should be divided into two equal-area parts.

计算研究表明：增大凹球面换能器的口径、减小几何焦距和提高中心频率均可以提高系统的侧向分辨率和轴向分辨率；但改变凹球面换能器的分割比例对两种分辨率影响不尽相同综合考虑超声换能器激励、聚焦性能以及产生的辐射力效果等因素，则换能器应按等辐射面积原则分割为宜。

The use of the ratio between the migration length and the diameter of the comet head (LDR, see Tice et al., 2000) as a parameter to represent the data of the genotoxic effects in D. polymorpha was found (Bolognesi et al., 2004) to be able to reduce the inter-individual variability of the data (from 20–30% for TL to 5–10% for LDR).

The paper analyzes the electrical corona phenomena, its effect to high_voltage transmission system and present detecting technology. It puts forward a double spectrums imaging system based on spectrum characteristic of electrical corona. It is all-weather and independent of environment radialization and temperature effect. It responds fast and can work in move .Two light ways image for a scene respectively: one way is UV image ,the other is visible image. Then we use image registration and infusion synthetically to form a complex image .The theory and methods of image infusion is explained.
