Abstract: The present invention relates to the technical field of catalyst preparation, disclosing a preparation method and application of a coated vanadium-tungsten-titanium oxide monolithic SCR catalyst. The method includes the steps of mixing a vanadium oxide precursor, a tungsten oxide precursor, titanium dioxide, an inorganic adhesive, an organic adhesive and a macromolecular surfactant with deionized water and stirring them to obtain a thick liquid; adding a pH adjuster to the thick liquid to make its pH 1.5-4.5; impregnating a cordierite honeycomb carrier in the thick liquid to obtain a preliminarily-impregnated catalyst and dried and calcined the preliminarily-impregnated catalyst to obtain a finished catalyst. The method has advantages such as simple operation, easy repetition and short time-consuming, so it can be applied to exhaust gas post-treatment of a marine diesel engine, and provide a good choice for catalysts used to denitrify medium and high temperature exhausted gas from marine engines.

Abstract: A system information transmitting method and apparatus, and a computer-readable storage medium are provided. The method includes receiving, at a terminal, a system call instruction sent by a browser, acquiring, at the terminal, target system information according to the system call instruction, dividing, at the terminal, the target system information into at least one data set, obtaining, at the terminal, encoded pseudo-touch event information by encoding the at least one data segment in the target system information according to a positional relationship of respective touch points in a simulated pseudo-touch event in a touch plane, and transmitting, from the terminal, as an input parameter of the target script, the encoded pseudo-touch event information to the target script through the browser.

Abstract: Provided is an apparatus for communication between a webpage and an operating system. The apparatus includes memory storing a first software for an operating system and a second software for a web browser. The apparatus also includes processing circuitry that executes the first software to provide the operating system including a clipboard and executes the second software to cause the web browser to access a web page. Further, a software (the first software or the second software) executed by the processing circuitry detects a message that is buffered in a clipboard provided by the operating system, and determines whether the message is in a preset format that is indicative of the software executed by the processing circuitry being a destination of the message. The software executed by the processing circuitry then processes the message when the message is in the preset format.
