Male Wistar rats were exposed daily to radon at a concentration of 100,000 Bq/m(3) for 16 h, and then exposed to 20% cigarette smoke for 1 h for a period of 75 d, with the radon cumulative dose reaching 200 WLM.

雄性Wistar大鼠每日暴露在浓度为100，000Bq/m(3)的氡中16小时，然后暴露在20％的香烟烟雾中1小时，为期75天，氡累积剂量达到200WLM。

According to the theory of flow diffusion and convection, three-dimensional state equation of radon field is established for constant and variable diffusion coefficient and convection rate. The numerical solutions for different coefficient and different boundary conditions are obtained for two models of radon field which have respectively source in the side and inside of collapse column.

根据流体场的扩散理论和对流理论，建立了扩散系数与对流速度为常量或变量情况下的氡气场三维状态方程；对於陷落柱柱体侧面有源氡气场和柱体体内有源氡气场两种理论模型，给出了不同系数和边界条件下的数值解的形式。

The information Radon coefficient wrap-around of the line on a finite field was caused by the modular arithmetic so that the Radon coefficient information in the periodic oscillations direction was processed with discrete cosine transformation, and other direction information was processed with wavelet analysis in order to reduce the wrap-around of rebuilding information. At the same time, according to the characteristic of the noise, one kind of denoising threshold selection plan was proposed.

正交有限脊波分析处理信息时，有限域平面上的直线由于模运算的存在而引起信息Radon系数的卷绕，为此，对Radon系数周期振荡方向的信息采用离散余弦变换处理，其他方向信息采用小波分析处理，以减少卷绕对信息重建影响；同时，结合图像信息中噪声的特点，提出了一种去噪浮动阈值的选取方案。

On the basis of the definition of the extraordinary Radon transform, the theory of rebuilding image from extraordinary Radon transform result is proposed, and some category such as image structure notation, topology of image structure notation and topological space, homeomorphism in topological space, equivalence of homeomorphism relation, topological constant of image structure notation.

与现有的基于区域内部或外形变换的形状分析方法相比，在理论方法上本质不同的是，本文提出的广义Radon变换，直接将原始的图象数据影射到特征空间，给出图象构图特征的描述，给出了可以用来进行图象检索或图象识别的结构特征谱。

Can form plenty of graphic images on Golden/ Slivery paperboard、 PET、 radon velum, it can have the effects like refraction veins, frosting veins, ice crystal, partial flower pattern, radon veins, three-dimensional cartoon.therfor it is a best choice for top-grade wine cases、drug and cosmetic package 、wall calendar、advertising poster、 gift etc.

折光压纹机属于无油墨，环保型的包装设备，能在金银卡纸、PET、镭射膜等包装产品上形成折光纹、磨砂纹、冰花、局部花纹、镭射纹、三维动画等效果，最适用于高档酒盒、药品、化妆品等包装及年画、挂历、广告宣传画等工艺品印刷，是当今包装印刷业的好帮手。

Based on that Radon can be integral along the line, moreover, IF of LFM and CW is a line on time-frequency plan, Radon transform and B-distribution are conjoined together.

Radon变换具有沿直线积分的特性，针对LFM信号和CW脉冲信号在时频平面上的瞬时频率是一条直线这一特点，将Radon变换与B分布结合在一起。
