Abstract: Disclosed are a microporous ceramic thick-film heating element for an electronic cigarette oil atomizing core and its manufacturing method. The microporous ceramic thick-film heating element includes a microporous ceramic substrate, a heating resistive layer and an electrode layer, and the heating resistive layer has a middle portion and two connecting portions, and the electrode layer includes two separated electrode films, and the two connection parts are connected to upper ends of the two electrode films respectively, and the middle portion is coupled to an upper surface of the microporous ceramic substrate, and the heating resistive layer is provided for heating microporous ceramic substrate to atomize a smoke oil of an electronic cigarette and disperse the atomized smoke oil from micropores of the microporous ceramic substrate to the outside.

Abstract: A method and apparatus for service login to a service provider sites have been disclosed. The method including: receiving a login request from a user, wherein the login request comprises at least both terminal's login information input by the user and third party account information pertaining to the user; after successful verification on the third party account information, determining by the service provider, whether the terminal's login information input by the user matches to reference login information, wherein the reference login information comprises specific information of the user to further identify user's identity; if the terminal's login information matches to at least a portion of the reference login information, delivering service to the terminal according to the third party account information.

Abstract: Various embodiments provide methods, apparatus, and systems for logging in an application account. A request for logging in an application account sent from a first terminal can be received. It is detected if the first terminal can be included in frequently used terminals corresponding to the application account. First verification information can be sent to a second terminal bound with the application account, when it is detected the first terminal is not included in the frequently used terminals corresponding to the application account. Second verification information can be received from the first terminal to detect if the second verification information matches the first verification information. When it is detected that the second verification information matches the first verification information, the request for logging in the application account can be responded.
