Abstract: A display method for a driving state is performed by a computer device and includes: displaying a first stable-state icon on a driving interface of a vehicle, the first stable-state icon being configured for prompting that the vehicle is in a first driving state; displaying a first available-state icon on the driving interface when a driving-state switching condition is satisfied, the first available-state icon being configured for prompting that the vehicle is able to activate a second driving state; and displaying a second stable-state icon on the driving interface in response to the vehicle being switched to the second driving state, the second stable-state icon being configured for prompting that the vehicle is in the second driving state.

Abstract: A bone screw comprises a threaded portion. The threaded portion has a first thread including a first front surface (11), a first back surface (12) and a crest. A second thread including a second front surface (16) and a second back surface (17) is formed on at least part of the crest of the first thread. Because of the presence of the second thread, a contact area between the screw and a bone and an axial pullout force-bearing area are both significantly increased, without significantly influencing the bending resistance, so that the mechanical property of the screw is entirely improved.
