Various embodiments of the teachings herein include a WLAN communication method. An example includes: receiving a polling request message at a client from an access point; checking whether the client is a polled client; if the client is the polled client, then sending a polling response message from the client to the access point; entering a function execution time window, and, when a moment for executing a function is reached in the function window, executing the function at the client. The function window starts when the client sends the polling response and ends before a retention time window starts. The retention time window begins with a safety time window and ends after it is expected that a polling response message will next be sent. The safety time window includes a period before a next polling cycle starts not less than an execution time of a function about to be executed.

The present disclosure provides a method for co-extraction of vanadium, titanium and chromium from vanadium slag. The method selectively reduces pyroxene and fayalite wrapped on spinel through low-temperature hydrogen reduction, iron removal by ferric chloride, and low-temperature leaching of the vanadium slag by oxalic acid, thereby destroying a structure of the spinel, dissociating a spinel phase and a silicate phase, and fully exposing the spinel phase. The method also directly leaches the vanadium slag at a low temperature by acidity and strong complexation of the oxalic acid, and destroys the structure of the spinel, such that vanadium, titanium, chromium and oxalate are complexed into a solution to co-extract vanadium, titanium and chromium. The present disclosure extracts vanadium, titanium and chromium from the vanadium slag, with a leaching rate each being greater than 99%.
