The calculation results show that the normal component of magnetic intensity is symmetrically distributed around the point of the acting force, where the normal component reach the maximum value; while the tangential component is antisymmetrically distributed around the point of the acting force, where the tangential component inverses its direction sharply.

结果表明，空气中扰动磁场的法向强度和切向强度分布特征明显不同，法向强度关于力作用点对称分布，并且在力作用点处达到最大，而切向强度关于力作用点反对称分布，并且在力作用点处有突变；地磁环境下，磁场对位移的影响可以忽略不计；扰动场强与外力成正比。

On October 31, 2008, information of Tang Shan everybody serves penannular jade ring of crown of limited company legal representative to entrust a lawyer, copy thick amount to 91 pages of 16 book size " antitrust investigates requisition ", sent a country industrial and commercial total bureau antitrust is in in an officer hand, application abuses the market to dominate antitrust investigation of the position to Baidu.

另据了解，为了提高点击率，全民医药网曾和百度河北代理商签了一个竞价排名协议，当全民医药网把竞价支付价格调低后，其在百度的链接便从8万多条信息一夜间降至4条。2008年10月31日，唐山人人信息服务有限公司法定代表人王冠珏委托律师，把一册厚达91页16开本的《反垄断调查申请书》，送到了国家工商总局反垄断处一位官员手中，申请对百度滥用市场支配地位的反垄断调查。

The improved model possesses band-pass filer characteristic, diffuses processing stability and satisfies the max-min principle. The simulation results show that the median filter is only proper for outlies noise and removes the thin line and corners of image. The linear filter extends or blurs the boundary of image. The anisotropic diffusion removes random noise effectively, but it brings about illusive edge and back diffusion for outlies noise. The improved model that possesses both median filter characteristics and anisotropic diffusion capability is proper for various mixed noise and can sufficiently protect the detailed characteristic such as corner, thin line and edge.

研究结果表明：中值滤波作为一种经典的非线性滤波方法仅适合于&飞点&噪声的滤波并引起图像的角点、线条损失，线性滤波扩大或使图像边界范围模糊；传统的各向异性扩散能对随机噪声有效地压制，但对&飞点&噪声会产生虚假的边缘甚至反扩散，而改进模型既具有中值滤波的特性又具有传统各向异性扩散的性能，适合于平滑不同强度与形状的混合噪声，并对角点、线条、边缘等细节信息提供足够保护。
