The main character of this control is to set the sheet gauge calculated by bounce formula as practice gauge which is compared with the setting gauge or lock gauge. The difference is the gauge difference value and is regulated by screw-down system. In such a way, the character of this system is increased and avoids the influence of such factors as roll wearing, roll heat expansion and so on. Therefore, it can greatly increase the accuracy of sheet gauge.

In the end, the synthesis condition and influential factors of PU-titania (TiO2) process, such as manufacturing sol (including the amount of water, the amount of PU/Titanium butyrate, the concentration of the solution, the pH value, the kind of alcohol), aging process, theoretical analysis of the dipping process, dry and heat treatment of the gelation, were also discussed especially. FT-IR、SEM、TEM、DLS techniques were applied to analyze and study the reaction mechanism and watch the surface and section of the PU-TiO2 membrane. According to above, it was inferred that PU-TiO2 membrane (containing K600) was better composite.

In order to establish the complete dynamic simulation model for the heat recovery steam generator and develop an advanced drum level controller, the methods of probability and time series were used to analyze the field data on drum level sloshing noise. The mean value of the drum level was removed and the field data was de-trended to get the true sloshing noise. Meantime, the AR model was set up for the drum level sloshing noise, and simulation results show that the model realizes matching simulation of the drum level noise signals in the power spectrum. The model can also match the drum level noise successfully in the time domain.
