5.The theoretical basis , intension , adjust mechanism , causes of formation and adaptive strategies of whole plant drought resistance were analysed , and the evaluating principle and standard of drought resistance ,indexes screening criteria of drought resistance and evaluating methods to whole plant drought resistance were also explored in the paper.
9.GOMBE water plant in Nigeria employs PLC to form the Distributed Control System (DCS) and adopts data transmission receiver wireless communication method between two PLC stations at 37km distance to form a set of SCADA system, which meet the data collection and monitor requirements for the whole plant and thus save the project investment.
