noun 下载 🔗分享 阴极 An electrode, of a cell or other electrically polarized device, through which a positive current of electricity flows outwards (and thus, electrons flow inwards). It usually, but not always, has a positive voltage. Examples : "In the battery powering his flashlight, the kathode attracts the negative electrons, allowing the light to shine. " 在他的手电筒电池里，阴极吸引负电子，使灯能够发光。 electronics physics energy device science technical 与AI对话词汇游戏阅读练习
noun 下载 🔗分享 阴极，负极 (by extension) The electrode at which chemical reduction of cations takes place, usually resulting in the deposition of metal onto the electrode. Examples : "During the electroplating experiment, the copper ions moved towards the kathode, coating it with a thin layer of shiny copper. " 在电镀实验中，铜离子向阴极（负极）移动，在它上面镀上了一层薄薄的、闪亮的铜。 chemistry electronics physics technical science 与AI对话词汇游戏阅读练习
noun 下载 🔗分享 阴极，负极 The electrode from which electrons are emitted into a vacuum tube or gas-filled tube. Examples : "In the old television, the kathode generated a beam of electrons that hit the screen to create the picture. " 在老式电视机里，阴极发射出一束电子，轰击屏幕从而产生图像。 electronics physics technology device electric 与AI对话词汇游戏阅读练习
