The electronic cigarette comprises: an electronic cigarette body; an indicator light group arranged in the electronic cigarette body; an angle detection device arranged in the electronic cigarette body, for detecting angle information of the electronic cigarette body; a control device, arranged in the electronic cigarette body, and connected to the indicator light group and the angle detection device, for controlling the indicator light group to display electric quantity according to the angle information of the electronic cigarette body.

Abstract: Provided is a preparation method of a detector material. The present disclosure epitaxially grows a buffer layer on a surface of a gallium arsenide substrate, deposits a silicon dioxide layer on the buffer layer, and etches the silicon dioxide layer on the buffer layer according to a strip pattern by photolithography and etching to form strip growth regions with continuous changes in width. Finally, a molecular beam epitaxy (MBE) technology is used to epitaxially grow the detector material in the strip growth regions under set epitaxy growth conditions. Because of the same mobility of atoms arriving at the surface of the substrate, numbers of atoms migrating to the strip growth regions are different due to different widths of the strip growth regions, such that compositions of the material change with the widths of the strip growth regions or a layer thickness changes with the widths of the strip growth regions.

Abstract: Embodiments of the present disclosure relate to a method, system, and computer program product for resizing an image. An image on a server is identified by a user through a terminal device, where the image has a first size. A image optimizer is positioned between the terminal device and the server. A image optimizer determines the display dimensions of the terminal device also determines that the requested image may need to be resized to a second size. The image optimizer receives the image from the server, resizes the image to the second size, and transmits the image to the terminal device.
