An anode active material for batteries including anode active substance particles that include a silicon oxide compound. The anode active substance particles includes lithium and a non-lithium doping metal, where the non-lithium doping metal includes a metal Mincluding one or more of titanium, magnesium, zirconium, zinc, aluminum, yttrium and calcium, and the content of the non-lithium doping metal in the anode active material is 0.01-20 wt %, for example 0.05-15 wt %, in another example 0.1-10 wt %, and in still another example 0.1-5 wt %. The anode active material has high water tolerance, and a secondary battery prepared from the anode active material has the advantages of high capacity, high coulombic efficiency and long cycle life.

A connection analysis method for a multi-port nested model and a medium. The method includes: acquiring instance information and nested relationships of a multi-port nested model, and building an instance relationship tree; reading port information and connection information of instances, and adding the port information and the connection information to the instance relationship tree; acquiring the port information and the connection information of the instances of each node layer by layer according to the instance relationship tree to build a connection dictionary; and acquiring port-to-port connection information of the instances by retrieving the connection dictionary to perform connection analysis on the multi-port nested model.
