摘要： Aluminum-phosphinimine complexes function as a component in a catalyst system for the (co)polymerization of ethylene. The inventive catalyst components form a highly productive polymerization system when activated with so-called “ionic activators”. The need for conventional transition metal catalyst metals (such as titanium, hafnium, zirconium or vanadium) is eliminated.

摘要： Organometallic complexes having two phosphinimine ligands and at least one activatable ligand are catalyst components for olefin polymerization. Preferred polymerization systems are prepared by combining the organometallic complexes with an ionic activator and/or an alumoxane. Preferred catalyst components contain titanium, zirconium, or hafnium and are activated with an ionic activator to form catalysts for ethylene polymerization.

摘要： The present disclosure provides a system constructed by connecting a mobile terminal and a service providing device, and a service providing method, wherein the service providing device and the mobile terminal are directly connected via an interface of the mobile terminal; the service providing device provides a service independently or through collaboration between the service providing device and various parties such as the mobile terminal and/or the background server based on the service information parsed and extracted the code information, identification information of any one or more parties among the user, the first mobile terminal, and the service providing device, and/or information bound to the identification information. Through active code scanning or passive code scanning or a combination of the two, the present disclosure may conveniently and quickly implement sensing access and effectively enhance security for operations such as mobile payment, etc.

摘要： The present disclosure relates to an information processing network based on uniform code issuance, a method for the same, and a sensing access device, wherein a releaser sends a corresponding code issuing request to a core administrator, such that the core administrator or a code issuing agency authorized by the core administrator generates a coding medium; in this way, when an accessing party identifies the coding medium with an equipped sensing access device, it may obtain information that matches the identified coding medium and further obtain the following information provided by the releaser, including: information to be released by the releaser, attribute state of the releaser, attribute state of an interacting party associated with the releaser, and information obtained from identifying other coding medium with the sensing access device equipped to the releaser. The present disclosure enables access based on a site-specific motif through various kinds of sensing access manners so as to accurately track respective nodes in the information dissemination process and realize circulation-based value quantization and cashing.
