扩散

The characteristic of accidents take on outburst,continuity,calamity,denseness,diffusibility and sociality etc, their harms and losing make people shocking by the sight, so it is important significance to manage,prevent and control the major hazard installations.

城市中发生的各类事故具有突发性、连续性、灾难性、密集性、扩散性和社会性等特点，其危害之大、损失之巨令人触目惊心，因此对城市重大危险源进行科学的管理、预防和控制，对降低事故的发生率具有重要意义。

One is based on the photoelectricity diffusibility reflection theory. In this method, an expensive photoelectricity sensor is laid closely with the signatures which are lightened by red LEDs. It will be judged by the analog reflection value from the detected area whether the signature is good or not. The other method uses the complex electronic image processing technology to identify some content in the signature.

Under the same pressure gradient, the seepage velocity of leaching solution well increases with the intensity of positive electric field, and decreases with the negative electric field. The seepage diffusibility of leaching solution and its wetting ability to fractured rock mass can be enhanced or weakened by the electric field.

在同等压力梯度下，受地电场作用的裂隙岩块中溶浸液渗流速度随正向电场强度增加明显增大，随反向电场强度增加明显减小；地电场能够强化或者减弱裂隙岩块中溶浸液的渗流扩散能力和溶浸液对岩块的润湿作用。
