Abstract: A method for detecting an abnormal application and a terminal are provided. The method includes: detecting a system event of a mobile terminal; reading process information if the system event is a triggering system event; determining whether a restarting process exists according to the process information; recording the number of restarting of the restarting process in a preset period; and determining that an application corresponding to the restarting process is abnormal, if the number of restarting is greater than a preset threshold. The method has a wide application scope for process detection, and may reduce energy consumption and resource occupancy while improving efficiency of abnormal application detection.

Abstract: The present invention relates to a variable tooth worm of worm gear sets used for a gear transmission mechanism. It comprises a shaft body with thread teeth. Its tip surface is a cylinder or a crowning surface, and the reference circle of the tooth flank is a revolution of a curved line. The worm product is made with variable tooth thickness and variable tooth height. During the meshing period, its loading capacity and transmission efficiency are increased and the transmission performance approaches a more ideal state because it has a greater number of simultaneously-meshing teeth than a cylindrical worm and also gradually gets into and out of mesh. It has a lower number of simultaneously-meshing teeth than a toroidal worm during the transmission period so that it has the advantages of lower heat value, lower oil-agitating loss, lower requirements for center distance and adjustment of axial position, easier manufacture as well as better economy.
