摘要:
A system and method are provided for modeling structured, semi-structured, and unstructured data all within a single instance of a user defined type (UDT) within a database store. In particular, the XML data model is extended to fields of a UDT. As a result, the properties of the XML data model—such as document order and document structure—can be preserved within instances of a UDT. Moreover, code representing object behavior (i.e., methods that can be invoked on an object in managed code) can be added to the UDT to operate on an XML field, as well as non-XML fields of the UDT. This enables a framework for adding business logic to XML data. The content model of the XML data can be optionally described using XML schema documents associated with the XML fields of the UDT.

The present invention relates to a system and methodology to facilitate XML data communications and processing. A diffgram data structure is provided that includes one or more states of a plurality of data records. The state information can be determined by examining one or more data sources for differences from one or more reference data sources. If differences are detected between the data sources, the diffgram can be constructed in an XML compatible format with both previous state indications and current state indications that describes the state differences between the data sources. Error information and/or other administrative information or codes can also be provided to facilitate database management and/or processing.

A method for modifying CNT is disclosed. The modified CNT by the above-mentioned method mixed with a resin is provided with an enhanced diffusibility; therefore the electronic property and mechanical property of resin are enhanced obviously with lower quantity of CNT.

The recycled thermosetting flour composites and method for preparing the same are disclosed. The silane coupling agent is used as a coincidental bridge between recycled thermosetting flour and plastic materials, to apparently promote the mechanical properties of composites by linking with each other. As a result, the recycled polyolefin and recycled thermosetting flour are applied through interfacial modification, coupling, modification, mixing and granulating process to generate a composite with better mechanical properties and recycle the resource.
