In a method of monitoring an apparatus for temperature control media supply of a tool of an injection molding machine, the apparatus for temperature control media supply has a feed and a return, between which at least one temperature control conduit is arranged, wherein at least one through-flow sensor is arranged. At least one temperature control conduit. At least one pressure drop is measured in the at least one temperature control conduit. At least one hydraulic resistance and / or at least one resistance change in the at least one temperature control conduit is calculated on the basis of at least one volume flow measured with the at least one through-flow sensor and on the basis of the at least one measured pressure drop, and the at least one hydraulic resistance and / or the at least one resistance change is visually represented. The present invention also relates to a temperature adjusting medium supply device serves for the mold for the injection molding machine and mold temperature control medium, a method of injection molding machine.

The invention relates to a method for removing arsenic and antimony in industrial wastewater by using smelting furnace slag. The method comprises the following steps: adding acid to the industrial wastewater containing more than 10mg / L of As and more than 10mg / L of Sb so as to adjust the acidity, and controlling the pH to 0.5-4; adding the smelting furnace slag and an oxidizing agent, enabling the smelting furnace slag to chemically react with or physically adsorb As<3+> and Sb<3+> in the wastewater under acidity and oxidation atmospheres, controlling the temperature at 40-100 DEG C, and carrying out heat preservation reaction for 1-3 hours; adding a neutralizing agent for neutralization, and controlling the pH to 6-9; filtering a solution so as to obtain filtrate and filter residues, if the As contained in the filtrate is less than 0.3mg / L and Sb contained in the filtrate is less than 0.5mg / L, meeting the residue removal standards, feeding the filtrate to a wastewater treatment system for further purifying other impurities, if the As contained in the filtrate is more than 0.3mg / L and the Sb contained in the filtrate is more than 0.5mg / L, repeating the steps till meeting the residue removal standards, and sending the filtrate residues to a filter residue yard for storage. The method has the advantages that the smelting furnace slag is used for replacing a precipitant so as to remove impurities, the arsenic and the antimony in the wastewater are rapidly and efficiently removed within 1 to 3 hours, the removal rate is close to 100%, the method is high in efficiency and low in cost, and the filter residues have good crystal structures, are easy to clarify and filter and contain arsenate and antimonite formed by iron, calcium, magnesium, aluminium, pentavalent arsenic and pentavalent antimony and have stable chemical property.

A method of generating an MRI image of an object in cyclic motion by acquiring ky line data in a spaced apart fashion over ky space using a predefined order for line acquisition for each of a number of position bands. The acquisition orders for adjacent bands are circularly shifted with respect to each other.

The invention has low requirements on process conditions, less equipment dependence and low cost, and is suitable for industrialization.

The embodiment of the present application discloses a dual-screen display method, device, device, and storage medium, which relate to the technical field of electronic whiteboards, and include: receiving a first touch operation for selecting a first area on the first screen; The target content is displayed on the second screen, and the target content is the display content in the first area; the second touch operation is received on the first screen, and the second touch operation is a writing operation; in response to the second touch operation, The writing track is displayed on a screen; the position of the first area on the first screen is adjusted so that the target content includes the currently written writing track. The above method can solve the technical problem of low utilization rate of the dual display screens when the user only uses one display screen, and display the user’s operation content through the second screen, which not only improves the utilization rate of the dual display screens, but also avoids the The occlusion of other users cannot watch the operation content.

The invention relates to a garment steamer (100) for treating garments, the garment steamer (100) comprising: a base (103); at least one rod (104) extending from the base (103); an ironing a plate (120), fixed relative to the at least one rod (104), for supporting the garment during handling; and a hanger (110), for hanging the garment (20) during handling. The garment steamer (100) also includes: a first coupling element (111) for allowing the hanger (110) to operate left / right along a first horizontal axis (A1) compared to the ironing board (120). Move right. This solution provides the user with the ability to adjust the position of the garment relative to the ironing board in an easy and versatile manner, allowing steaming and / or ironing of entire areas of garments of different sizes, widths, lengths and types without interacting Replace the pieces on the garment steamer.

The invention discloses a method for removing arsenic from an acidic arsenic-containing solution by using an iron salt. The method comprises the following steps: (1) adjusting the pH value of the acidic arsenic-containing solution, stirring and heating the adjusted solution, and adding a ferrous salt to obtain a mixed solution; and (2) adding magnetite to the mixed solution, adding an oxidant, stirring, heating and reacting the obtained solution, and filtering the solution to remove scorodite filter residues in order to complete the removal of arsenic in the acidic arsenic-containing solution.A precipitate obtained after arsenic precipitation of new highly-active crystal seeds is iron arsenate with a good crystal form, and has the advantages of high arsenic content, small size, complete crystal form structure, low toxicity leaching concentration of arsenic, good long-term stability, and easiness in clarification, filtration and separation. The method has the advantages of mild processconditions, simple process, convenience in operation, small dosages of reagents, small amount of arsenic iron residues, low price and low cost of the raw material, and realization of the production of the iron arsenate precipitate-scorodite with the good crystal form from the acidic arsenic-containing solution of copper smelting flue dust.
