The coating exhibits strong photocatalytic activity under ultraviolet irradiation. as a result, it can oxidize most organic and inorganic pollutants, and kill bacteria such as e. coli and vibrio cholerae in seconds. this leads to a very attractive and safe technology for water treatment
這層具催化效能的薄膜受到紫外線照射時，會產生強烈的氧化作用，可以氧化大部份有機及無機的污染物，並能瞬間殺死大腸桿菌、霍亂弧菌等細菌。Abstract : in this paper, we proposed a diffusion equation for simulating the problem of pollution, and discussed its application to point pollution, especially while instantaneous point pollution happened. finally, we gave the numerical analysis
文摘:給出了一個適合於模擬污染問題的擴散方程，討論了它在點污染，尤其是在瞬時點污染發生時的應用.並對一些實際算例進行了分析By the theoretical derivation, the equation of the vertical homogeneous mixing distance of the continuous and instantaneous point source is developed. the definition of the part depth of homogeneous mixing is given, and its equation is obtained. these equations are verified by the measure data, such as the data of nanjing section in yangtse river, and the results are satisfied
通過理論推導，分別得到瞬時點源和連續點源濃度場在垂向上達到全水深均勻混合的縱向距離的理論計算公式；進一步研究排放口至全水深均勻混合距離之間水域的污染物垂向紊動混合過程，首次提出了部分均勻混合水深的新概念，推導得到部分均勻混合水深隨縱向距離變化規律的表達式。Calculate based on the first two pollutant concentrations, which involves simulating hundreds of chemical reactions in many locations at very high frequency fine time steps
