Abstract: Provided are a display panel including multiple scan lines located in the display region and gate drive unit groups located in a non-display region. The gate drive unit groups include at least one first gate drive unit group and at least one second gate drive unit group. The first gate drive unit group includes multiple cascaded first gate drive units. The second gate drive unit group includes multiple cascaded second gate drive units. The first gate drive units and the second gate drive units are connected to different scan lines. A first period during which a first gate drive unit at the first stage transmits an effective level signal to a scan line and a second period during which a second gate drive unit at the first stage transmits an effective level signal to a scan line overlap, overlap duration is t, and t>0.

Abstract: Disclosed is a novel cartridge feeding system for a gun, relating to the technical field of guns. The system comprises a gun barrel, a chamber, a grip, and a trigger set. A feeding rail is arranged between the grip and the chamber, the trigger set is located at the bottom of the feeding rail, and one end, away from the grip, of the trigger set is provided with a magazine. The upper side of the magazine is connected to the inner bottom of the feeding rail, a rotatable feeding ramp is hinged to the bottom of one end, close to the feeding rail, of the chamber, a bolt is movably arranged in an upper half part of the feeding rail, and a movable cartridge extraction/pushing hook is hinged to the bottom of one end, close to the chamber, of the bolt.

Abstract: A modeling method is provided. The modeling method includes: extracting multiple pieces of logging data corresponding to a plurality of logging characteristic parameters at different drilling depths of a sample well, based on a logging information of the sample well; marking the different drilling depths based on a lost circulation information of the sample well to distinguish lost circulation points and non-lost circulation points; and classifying the lost circulation points and the non-lost circulation points by adopting a random forest algorithm, based on the plurality of logging characteristic parameters and the multiple pieces of marked logging data at the different drilling depths, to establish a plurality of corresponding relations between the logging characteristic parameters and a lost circulation or non-lost circulation result, so as to obtain a diagnosis model.

Abstract: An ammunition assembly is provided, which includes a projectile and a fixture, where the projectile includes a penetrating, a sabot and a sabot holder, the sabot is sleeved on an outside of the penetrating, the sabot is of a split structure, the sabot holder is sleeved on an outside of the sabot, the sabot holder is located at one end of the sabot far away from the penetrating; the projectile is slidably provided in the chamber; the fixture includes clamping blocks, the clamping blocks are movably provided in the gun barrel, and the clamping blocks are capable of extending into the chamber and blocking the sabot holder.

Abstract: An object processing method includes: detecting, on a client, a first target gesture performed on a first target area in a virtual scene displayed on the client; displaying a second target area on the client in response to the first target gesture, the second target area including a plurality of to-be-processed objects in the virtual scene; detecting, on the client, a second target gesture performed on a first target object in the plurality of to-be-processed objects; and using the first target object in the virtual scene, displaying the first target object in a third target area in the virtual scene, and hiding the second target area in the virtual scene in response to the second target gesture. The third target area is a shortcut display area of the client.

Abstract: Embodiments of the present disclosure provide a method for controlling the movement of a virtual object performed by an electronic device. A first button is displayed at a first position of a screen. A second button is displayed at a second position of the screen when a first touch operation is detected. When a second touch operation on the second button is detected, a virtual object is controlled to move automatically, and the two buttons are highlighted. The automatic movement of the virtual object and the linkage between the two buttons are implemented through simple operations, thereby improving the convenience and flexibility of operations.
