A thermoplastic composite material has an inner layer material and at least one layer of outer layer material. The inner layer material is a core layer that contains fiber bundles, a first thermoplastic resin and a first auxiliary agent; and the at least one layer of outer layer material wraps the core layer and is a resin layer comprising a second thermoplastic resin and an optional second auxiliary agent. The fiber bundles extend continuously from one end of the core layer to the opposite end thereof. The inner layer-outer layer composite structure improves the processing performance of the thermoplastic composite material and the lubricity between fibers and resin matrixes during injection molding, and improves the fluidity of the fibers in a resin matrix melt.

Thermoplastic composite material, preparation method therefor and use thereof

A mechanical and hydraulic dual-effect expansion device for well drilling with expandable tubular technology includes an anchor having a lower end connected to an upper end of an insertion connection tube via a coupling, a hydraulic cylinder assembly comprising a hydraulic cylinder and a piston tube movably disposed within an inner cavity of the hydraulic cylinder, and a variable-diameter expansion cone assembly comprising a sealing cone portion and a variable-diameter expansion cone portion, wherein the sealing cone portion has an upper end connected to a lower end of the piston tube and a lower end connected to an upper end of the variable-diameter expansion cone portion. The mechanical and hydraulic dual-effect expansion device can facilitate completion of construction operations of an expandable tubular in a casing and an openhole system.

Indexing and querying in multiple languages is accomplished using an ordered chain of filters and/or other such components. When receiving information to be indexed or for a query, the information can be tokenized and typed based at least in part on the language of each token. The character types can be adjusted if appropriate for the languages, and the tokens can be further segmented using a dictionary for the respective language types. Once appropriate tokens are determined, relevant synonyms in each appropriate language can be determined and typed accordingly. If necessary the case of the tokens and synonyms can be adjusted and further segmented based on punctuation. The terms and synonyms then can be used as part of the index or as part of the search query to include other terms or phrases based on relevance to the original information.
