The method comprises: measuring and calculating a value of an asymmetry delay of the 1588 uplink/downlink; performing an asymmetry delay compensation when the value of the asymmetry delay exceeds a set synchronization offset range; and continuing a normal 1588 time synchronization if the value of the asymmetry delay does not exceed the set synchronization offset range; and implementing the automatic compensation for the asymmetry delay of the 1588 link. The above-mentioned scheme can correct the asymmetry delay automatically, and ensure the quality of 1588 time synchronization.

Abstract: A superhydrophilic thin film is formed on a metal surface of a boiler vessel to alter the wettability and roughness of the surface, which, in turn, changes the boiling behavior at the surface. The superhydrophilic film is formed by depositing a layer of a first ionic species on the surface from a solution. A second ionic species having a charge opposite to the that of the first ionic species is then deposited from solution onto the surface to produce a bilayer of the first ionic species and the oppositely charged second ionic species. The depositions are then repeated to form a plurality of bilayers, on top of the preceding bilayer. The bilayers are then heated, leaving the second ionic species on the metal surface to form a superhydrophilic film.
