    Pyrolysis and melting processes for municipal refuse treatment have been developed as an alternative of incineration process for decreasing several pollution problems caused in the incineration process. The plants of pyrolysis and melting process developed by Nippon Steel Co., Ltd. are already in operation at Ibaraki City and Kamaishi City. The plant based on purox process, one of the pyrolysis and melting process developed by showa Denko Co., Ltd. and Union Carbide Co., Ltd., started operation on November of 1981 at Chichibu City. For evaluating these pyrolysis and melting processes in terms of the alternatives of incineration process, the authors built the mass and heat model covering these processes based on gasification theory by use of experimental data of bench scale pyrolysis equipment and simulated the operation of plant by varying the operating factors. The model proposed by the authors was effective for evaluating the pyrolysis and melting process by comparing the simulation results and the observed operating data.

    In the first and second parts of the series of our reports, studies on the development of new automatic measuring methods and apparatuses for nitrate and nitrite ions, phosphate ion and dissolved organic substances were reported. Development of an automatic measuring station for the eutrophic substances in sea water was also reported.
    In this third part, results of the measurement of eutrophic substances in sea water are described. From the twice experiments, the first experiment was carried out from January to February 1979 and the second one was from August to September 1979, interesting results were obtained.
    It was found that the concentration of the eutrophic substances varied remarkably and it decreased at high tide. Almost all eutrophic substances were supposed to be provided from bed of the sea.

    Transmission of water is conformed to both the equation of motion and the equation of continuity. But, among the distribution networks of water supply, the collection sewers of drainage system, the distribution pipelines of regionalized water supply and river networks, those which are on the laters in above increase in their tendency of compulsory transmission. In other words, the laters transmission are controled more by the equation of continuity than by the equation of motion.
    In this thesis, “Markov Process—it is quite a theory of probabilistic continuity—”is treated as an approach of distribution control planning. In such a control, it is dif-ficult to find the operating root (arc) and operating rate. And for us to have such problems will be a large load.
    I report the results of some application of this method on distribution networks and discuss them in this paper.
