Abstract: A method and an apparatus are provided. Distribution information in a first attribute dimension is acquired from a persona data collection of users who use a network service. The persona data collection includes persona data sets corresponding to the users. An evaluation data collection to match the distribution information in the first attribute dimension is extracted from a sample data collection that is collected from sample users. The sample data collection includes sample data sets corresponding to the sample users. Further, a level of accuracy of the persona data collection in a second attribute dimension is determined based on the evaluation data collection in the second attribute dimension.

Abstract: A vehicle includes a spare wheel, a jack and a jack wrench. The jack and a jack wrench are provided to raise the vehicle to allow a user to remove a damaged wheel and replace it with the spare wheel. The jack and jack wrench are secured to the vehicle via a first connector. The spare wheel is then secured to the first connector via a second connector. The second connector extends through the spare wheel and into the first connector to secure the spare wheel to the first connector and thus to the vehicle.

Abstract: The present invention relates to a method for producing europium activated yttrium gadolinium borate phosphors and a product produced by the method. The chemical formula of said phosphors is (Y1-x-y-zEuxGdyMz)BO3, wherein: 0.01?x?0.01, 0?y?0.5, M=Ca, Sr, Ba or Mg, 0?z?0.1. The method comprises: mixing a yttrium source, an europium source, a gadolinium source, a boron source and an M source to produce an aqueous solution in a microwave system; placing the aqueous solution into a microwave system, and making the solution reacting under the condition of condensation cycling and stirring to produce a sol; heating the sol in a microwave system to produce a gel; drying, baking, washing and collecting the gel to produce the product. The method of the present invention can greatly short the production period and improve the production efficiency. The europium activated yttrium gadolinium borate phosphor particles is of a particle size as fine as 80 nm and has good uniformity and emitting performance.
