污染物

The first step of simulation method is to establish the one-dimension parabolic partial differential advection diffusion equation that was used to describe the mass transportation model of air-pollution distribution as a block program model of the controllable plant. Then, applying the Fuzzy logic theory to operate tunnel jet-fans and control the tunnel wind quantity and adjust the wind average velocity would not let the air-pollution concentration over the standard safety value too much.

模拟方式首先将常被用以表示隧道内空气污染物质传理论模式之一维向平流扩散抛物线型偏微分方程式建构成一组可控制对象的方块程式模拟模型，再运用模糊逻辑理论模拟控制喷流式通风机之运转风量来调节隧道内平均风速以控制隧道内空气污染物浓度不至於高过标准安全值太多。

At last, the particle movement and theadvection-diffusion movement of pollutant in Tianjin sea area were carried out.

最后，考虑了排污的影响，计算了天津海域排污口处的质点在渤海海域的运动状况和排出污染物的对流扩散运动及其分布。
