According to the present invention, a plurality of images are incorporated in a synthetic image file in accordance with certain synthesis rules. When a webpage is browsed, only one image file needs to be loaded, which is equivalent to that all images required to be displayed on this webpage are loaded. Then, by setting CSS attributes, the synthetic image file is set as a background image. The background image is moved relatively by setting a margin value of the background image, so that an image display position on the webpage is able to display a required corresponding image that is comprised in the synthetic image file. The application method, in which a same image file is loaded once and used multiple times, undoubtedly greatly reduces phenomena of a time delay and incomplete image display when a large number of images need to be displayed on a webpage.

The invention provides a method for asynchronous positioning of an ultra-wideband sensor network based on compressive sampling. The method comprises the following specific steps that (1) an anchor node 1 broadcasts ultra-wideband pulse 1; (2) other anchor nodes and a TAG node carry out compressive sampling on a received signal to obtain a time of arrival of the pulse 1; (2) the TAG node broadcasts ultra-wideband pulse 2; (4) each anchor node respectively carries out compressive sampling on the received signal, the anchor node 1 records a pulse round-trip time, and other anchor nodes obtain a time of arrival of the pulse 2 and respectively report the two times of arrival to the anchor node 1; and (5) the anchor node 1 computes a coordinate position of the TAG.
