The semiconductor contact layer has a first thickness greater than 50 ? and smaller than 1000 ?.

Abstract: A multimodal method for detecting video includes following step of: receiving a message to be detected to obtain a multimodal association result, which message to be detected corresponds to a video to be detected; generating a plurality of detecting conditions according to multimodal association result; searching a plurality of videos in a video detection database to obtain a target video in videos according to detecting conditions, which each of videos includes a plurality of video paragraphs respectively, which each of video paragraphs includes a piece of multimodal related data respectively; comparing detecting conditions and piece of multimodal related data of video paragraphs to obtain a matching video paragraph and using video corresponding to matching video paragraph as the target video; and outputting the target video and the video to be detected to a display device for display.

Abstract: A device and a method for detecting a purpose of an article are provided. The device is configured to divide the article into a plurality of sentences and input the sentences to a feature identification model to generate a contextualized word vector corresponding to each of the sentences. The device further inputs the representation to a specific purpose detecting model to generate a distributed representation similarity of the article. When the distributed representation similarity of the article is greater than a threshold, the device determines that the article conforms to a specific purpose.

Abstract: A photocatalytic electric fan comprises a main body having a receiving tank therein. A motor is fixed in the receiving tank. A rotation shaft of the motor is connected with a fan blade. A lamp-fixing element is joined at an opening of the main body near the fan blade. A photocatalytic lamp is positioned on the lamp-fixing element. At least a photocatalytic lamp tube is disposed on the lamp. Each photocatalytic lamp tube is connected to an electric connection seat, a stabilizer, a starter, a switch, and a power source. A face net is joined at the other opening of the main body. The face net is rotatable. The photocatalytic lamp tube is a UV lamp tube with a glass-fiber-cloth sleeved outside. The glass-fiber-cloth has a photocatalytic coating formed of titanium dioxide.
