摘要： This invention relates to a supported nonmetallocene catalyst for olefin polymerization, which is produced by directly reacting a nonmetallocene ligand with a catalytically active metallic compound on a carrier through an in-situ supporting process. The process according to this invention is simple and feasible, and it is easy to adjust the load of the nonmetallocene ligand on the porous carrier. The supported nonmetallocene catalyst according to this invention can be used for olefin homopolymerization/copolymerization, even in combination with a comparatively less amount of the co-catalyst, to achieve a comparatively high polymerization activity. Further, the polymer product obtained therewith boasts desirable polymer morphology and a high bulk density.

摘要： The present invention relates to a magnesium compound-supported nonmetallocene catalyst, which is produced by directly contacting a catalytically active metallic compound with a nonmetallocene ligand-containing magnesium compound, or by directly contacting a nonmetallocene ligand with a catalytically active metal-containing magnesium compound, through an in-situ supporting process. The process is simple and flexible. In the process, there are many variables in response for adjusting the polymerization activity of the catalyst, and the margin for adjusting the catalyst load or the catalyst polymerization activity is broad. The magnesium compound-supported nonmetallocene catalyst according to this invention can be used for olefin homopolymerization/copolymerization, in combination with a comparatively less amount of the co-catalyst, to achieve a comparatively high polymerization activity. Further, the polymer product obtained therewith boasts high bulk density and adjustable molecular weight distribution.

摘要： A voice-based telecommunications login system which includes a login process controller; a speech recognition module; a speaker verification module; a speech synthesis module; and a user database. Responsive to a user-provided first verbal answer to a first verbal question, the first verbal answer is converted to text and compared with data previously stored in the user database. The speech synthesis module provides a second question to the user, and responsive to a user-provided second verbal answer to the second question, the speaker verification module compares the second verbal answer with a voice print of the user previously stored in the user database and validates that the second verbal answer matches a voice print of the user previously stored in the user database. Also disclosed is a method of logging in to the telecommunications system and a computer program product for logging in to the telecommunications system.
