摘要： The present invention discloses a method and a device for audio signal classification, and relates to the field of communications technologies, which solve a problem of high complexity of type classification of audio signals in the prior art. In the present invention, after an audio signal to be classified is received, a tonal characteristic parameter of the audio signal to be classified, where the tonal characteristic parameter of the audio signal to be classified is in at least one sub-band, is obtained, and a type of the audio signal to be classified is determined according to the obtained characteristic parameter. The present invention is mainly applied to an audio signal classification scenario, and implements audio signal classification through a relatively simple method.

摘要： Computer-readable media, computer systems, and computing devices facilitate providing a comparison experience to a user in response to a search query. Upon receiving a search query from the user, entities are extracted from the query. The entities are associated with entity classes. The entities, entity classes, previous user behavior, and other information are used to infer whether the user likely is engaging in a comparison task. If the inference indicates that the user likely is engaging in a comparison task, a comparison experience is generated and access to the comparison experience is provided to the user.

摘要： Methods, computer-storage media, and graphical user interfaces are provided for identifying and presenting rich related sites for task-oriented search queries. Upon receipt of a search query input by a user, one or more query logs are analyzed to determine if the search query is a related to a task being performed by the user. If the query is determined to be a task-oriented search query, search results are identified, as is one or more Uniform Resource Locators (URLs) related to a particular search result. The related URL is presented to the user in association with the particular search result. Additional controls, e.g., search tools that facilitate querying of those URLs determined to be relevant to a particular search result, may also be provided to aid the user in performing the task at hand.

摘要： Fenton and Fenton-like system enhancing agent and the usage thereof are provided. It relates to a water treatment enhancer (enhancing agent) and the usage thereof. It widens water pH range of Fenton and Fenton-like system reaction. It reduces amount of Fe2+ required for Fenton reaction. It increases rate of Fenton-like reaction. The enhancing agent is selected from sodium sulfite, lithium sulfite, potassium sulfite, magnesium sulfite, calcium sulfite, hydroxylamine hydrochloride, hydroxylamine perchlorate, hydroxylamine sulfate, hydrazine, N,N-diethylhydroxylamine, amino ethanolamine, hydroxylamine solution or N,N,N′,N′-tetrasubstituted p-phenylenediamine. The method of use of enhancing agent comprises the steps of: adding Fenton or Fenton-like system enhancing agent, an agent for enhancement and hydrogen peroxide into water subject to treatment; and mixing and allowing reaction. The enhancing agent can increase the rate of reaction for the water treatment and reduce the dosage of the agent for enhancement.
