5.Distributed control system (DCS), with the characteristic of centralization of its management and the distribution of its functions, burthen and malfunction, is widely used in the process of modern industry.
6.If the learning strategies are used efficiently by a public English learner, not only the learning efficiency can be increased on a large scale, but also the lesson burthen can be relieved to some extent and the learning condition of the learners can be greatly ameliorated.
7.This thesis analyzes the control principles of energy regulating ways in reefer units, compares the merits and demerits of these control methods in the outside working conditions of the changing burthen, and then puts forward the WVF, a entirely new energy saving regulative and control method.
8.Distributed control system (DCS), with the characteristic of centralization of its management and the distribution of its functions, burthen and malfunction, is used widely in the process of modern industry, and become one of the most active branch.
9.Due to a good effect of grain sludge, SUFR system has a function of nitration, denitrifying and denitrifying phosphorus. All kinds of creature in this SUFR system shape steady animalcule communities, its not only improved systemic capacity of resisting sludge burthen, but also ensured effect ofbiological nitrogen removal and biological phosphorus removal, making the effluent quality of SUFR system is up to with the first class of discharge standard of pollutants for municipal wastewater treatment plant (GB8978-1996).
