Settling Process

The analysis of the distribution of radionuclides in the products of blast furnace and steelmaking melting operation processes is carried out. It was shown that the blast furnace melting process is considerably affected by natural radionuclides whereas steelmaking furnace process - by technogenic ones. The main impact on the environment is exerted by the gas-dust fraction, which contaminates the surrounding soil, vegetation and ground water during the settling process. An additional dose of external irradiation of the population and personnel is created by slag and metal fractions. High radiation doses are possible in case of ingestion of high-intensity sources of 60Co and 137Cs into the melt. Internal irradiation of people occurs due to gas and dust emissions.

The movie and TV art industry of Weifang especially the theater is researched as the object in this paper. After looking through a large number of reference, the main factors influencing the management of the movie and TV art industry are determined. The evaluation system of the movie and TV art industry management is constructed. Using AHP to get the weight of each evaluation factor, the five-dimension set is established as excellent, good, general, poor, very poor. Using the expert group to score the second-level influencing factors, the evaluation vector of the movie and TV art industry management could be obtained. According to the maximum principle to determine the evaluation results of the movie and TV art industry management, and a simulation calculation is carried out.
