Abstract: A page-loading method is applied to a terminal and includes: sending a page access request to a server, downloading page content returned by the server, and acquiring page content download information; parsing out a loading optimization script and address information of one or more to-be-loaded page elements from the page content; running the loading optimization script, and acquiring a current loading quality parameter for the one or more to-be-loaded page elements according to the page content download information; and loading the one or more to-be-loaded page elements according to the address information of the one or more to-be-loaded page elements and the current loading quality parameter.

Abstract: A method for lazy loading of JS scripts includes: determining whether a target browser supports a sequential execution function of an async attribute; if the target browser supports the sequential execution function of the async attribute, creating a script tag for each of the JS scripts based on a URL address for each of JS scripts to be lazily loaded, and setting async=false for each script tag; and sequentially inserting each script tag into an HTML document according to a script execution order of each of the JS scripts, so that the target browser downloads each of the JS scripts in parallel, and executes each of the JS scripts according to the script execution order.

Abstract: The disclosure discloses a dynamic attitude measurement method of a star sensor based on gyro's precise angular correlation. On the basis that a dynamic compensation is performed on each of the measurement exposure frames of the star sensor and a fixed star matching vector matrix having dynamic error and noise influence is obtained in a prior art, a transform matrix between every two adjacent measurement frames of the star sensor is precisely measured by a unit including three gyros fixedly coupled with the star sensor. The transform matrix correlates the matched vector matrixes of the adjacent measurement frames of the star sensor. Finally, a correlated measurement equation is established with a series of correlated measurement frames, which is corresponding to processing a series of measurement frames as a single measurement frame.
