Abstract: A preparation method of glassless grain-oriented silicon steel includes the following operations. During a decarburization annealing, a thickness of an oxide film on a surface of strip is 1.5-2.5 ?m; an atomic weight ratio of Si element and Fe element in the oxide film satisfies: Si/(Si+Fe)?0.76; during a high-temperature annealing, a cooling stage includes sequentially: cooling with an inner cover when a temperature drops from 1200° C. to 500° C.; wherein a protective gas is a mixed gas containing nitrogen and hydrogen, and a volume percentage of the hydrogen in the mixed gas is >3%; cooling with the inner cover when the temperature drops from 500° C. to 200° C.; wherein the protective gas is nitrogen; and cooling in air by removing the inner cover when the temperature is <200° C.

Abstract: A method, eNB, UE and system for reducing measurement signalling in a LTE network at an eNB side are provided, including: a reported measurement result containing a physical cell identifier of a neighboring cell is received; the physical cell identifier of the neighboring cell is mapped; and the physical cell identifier of the neighboring cell is sent when determined to be unsuccessfully mapped. Another method for reducing measurement signalling in an LTE network at a UE side is also provided, including: signal strengths of a serving cell and a neighboring cell are measured, and a measurement result is reported; and when the measurement is performed again after an unsuccessfully-mapped physical cell identifier of the neighboring cell is received, a physical cell of the neighboring cell corresponding to the unsuccessfully-mapped physical cell identifier of the neighboring cell is not measured.
