Abstract: According to an example, a first terminal device uploads sharing information to a server, the server sends identification information related to the sharing information to the first terminal device according to the sharing information, and the first terminal device transforms the identification information into a sound signal, and plays the sound signal. a second terminal device receives the sound signal, parses the sound signal to obtain the identification information, and sends a download request comprising the identifier information to the server. The server sends the sharing information to the second terminal device according to the download request.

Abstract: An interactive method, apparatus based on an image and a server are provided according to embodiments of the present invention. The method includes: recognizing a face region in an image; generating a face box corresponding to the face region; generating a label box corresponding to the face box; and representing label information corresponding to the face region in the label box by performing one of the following modes: obtaining the label information corresponding to the face region from a server, representing the label information obtained from the server in the label box; and receiving the label information corresponding to the face region inputted by a user, representing the label information inputted by the user in the label box. Thus, based on the label information provided by the server or the user, information associated with a circled region is customized (e.g., reviews information), and is further pushed to an associated friend.

Abstract: The present invention provides an etchant which is a reaction product of sulfuric acid and ammonium persulfate, wherein the concentration of the ammonium persulfate is 1˜25%, the concentration of the sulfuric acid is 98%. The etchant is produced by adding the ammonium persulfate into the sulfuric acid at a temperature of 100 to 200 degree Celsius. According to the present invention, the ammonium persulfate substitute the conventional oxidizing agent of hydrogen peroxide. Since the ammonium persulfate is in a powder form, the operation becomes more convenient. Furthermore, since sulfuric acid is formed as a by-product instead of water, the etchant will not be diluted after being used for many times, which reduces the production cost.

Abstract: The present disclosure relates to the technical field of wireless network communications, and provides a method, system and client for uploading an image, a network server and a computer storage medium. The method includes: a client determines an image to be uploaded, generates a unique image identifier corresponding to the image to be uploaded, and transmits an image detection request to a network server; the network server detects whether there is an image having the same image identifier in the network server according to the image identifier included in the image detection request, and returns a detection result to the client; when the detection result is that there is not an image having the same image identifier in the network server, the client uploads the image to be uploaded in the form of multi-part uploading to the network server; and after the image to be uploaded is uploaded successfully, the network server records the image identifier, and returns an upload success response to the client.

Abstract: Filters are generated by analyzing a set of search results most relevant to a search query to determine filter values that may be of most interest to the user. A search query is received and is classified into a query segment that best corresponds to the search query so that filter categories associated with the query segment can be identified. Based on an analysis of search results most relevant to the search query, metadata associated with these search results is used to formulate filter values for each filter category. The filter values are ordered based on their respective frequency of presence in the search results. The search results, along with the filter categories and filter values, are communicated for presentation.

Abstract: A stormwater filtration system suitable for treatment of stormwater runoff in a developed environment uses a treatment bay that includes a filtration bed with live plant matter and a plurality of functional layers. The filtration bed may include an adsorption layer or area that contains a phosphorus adsorptive granular media. In accordance with another aspect, the filtration system includes a layer of permeable pavers.

Abstract: A rotary mechanism includes an upper seat pan, a lower seat pan and an arc slideway mechanism. The upper and lower seat pans are connected at their sides and can rotate relative to each other. A middle inner slide rail of the arc slideway mechanism, which has a long through-hole in its center and is fixed to the lower seat pan, is positioned between an upper supporting plate and a lower supporting plate, both of which have a long aperture in their respective centers. Fixed parts run through the long through-hole and the long apertures, and fix an upper outer slide rail and a lower outer slide rail. A locking mechanism having portions fixed to the upper seat pan and the lower seat pan, respectively, is arranged to cooperate with the arc slideway mechanism to limit relative rotation of the upper and lower seat pans.
