Abstract: Provided are an aluminum scandium alloy target and a method of manufacturing the same. The method comprises: preparing metal aluminum and metal scandium with purities of 99.99% or more respectively; mixing the metal aluminum into the metal scandium and smelting through a plurality of cycles to obtain a desired aluminum scandium alloy, in which the metal scandium account for 5-40 wt % and the metal aluminum account for 60-95 wt %; injecting the aluminum scandium alloy into a mold to obtain an aluminum scandium alloy target billet; and mechanically processing the billet to obtain the aluminum scandium alloy target. The method addresses the problems of the prior art in which uniform distributions of ingredients in the target are difficult to achieve, scandium is not uniformly distributed, and the target has a high oxide content, a low compactness, a low alloy purity and are unsuitable for manufacturing a sputter coating.

Abstract: The present disclosure relates to adaptive cruise control in the field of automatic driving, and discloses a vehicle control method, an apparatus, an electronic device and a storage medium. A specific implementation is: firstly, determining a target travelling scenario according to real-time monitoring data upon fulfilment of a preset update condition; then, determining a target time headway according to the target travelling scenario, where the target time headway is used to dynamically adjust a relative motion state between an host vehicle and a surrounding vehicle; and finally, controlling a vehicle according to the target time headway. It solves the problem of the prior art in overemphasizing the state of the vehicle ahead for automatic driving control while overlooking the perception of the driver or passenger of the host vehicle in the travelling scenario can prompt the driver to manually intervene, compromising the experience of the automatic driving.
