Abstract: Embodiments of this application disclose a terminal antenna and an electronic device, and relate to the field of antenna technologies, which can better cover a medium-high frequency band, provide a good bandwidth and good radiation performance, reduce hardware costs, and have a good SAR, thereby better supporting a wireless communication function of the electronic device. A specific solution is as follows: The terminal antenna includes: a first radiator, a feed point, and a ground point. One end of the first radiator is grounded by using the ground point, and the other end of the first radiator is provided with the feed point. The first radiator is further provided with a slot that penetrates the first radiator, the slot is of an interdigital structure, and there are at least two slots.

Abstract: Provided is an engineered bacterium for producing nervonic acid and/or grease. The genome of the engineering bacterium is integrated with an expression cassette expressing a protein encoded by 3-ketoacyl-CoA synthase (KCS) gene and/or an exterase gene.

Abstract: A wind farm control strategy method, apparatus and device, and a storage medium are provided. The method includes: acquiring incoming flow wind data of a target wind farm, a restriction relationship between wind turbines in the target wind farm and current working condition data of the wind turbines in the target wind farm; inputting the incoming flow wind data, the restriction relationship and the current working condition data into a pre-trained working condition prediction model to obtain target working condition data corresponding to a target generation power of the target wind farm, the target generation power being a maximum generation power of the target wind farm; and controlling operation of the wind turbines in the target wind farm based on the target working condition data.
