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 : "Electrons flowed into the cathode of the battery as it charged. " 当电池充电时，电子流入电池的阴极。 electronics physics technology device electric machine science 与AI对话词汇游戏阅读练习
noun 下载 🔗分享 阴极 (by extension) The electrode at which chemical reduction of cations takes place, usually resulting in the deposition of metal onto the electrode. Examples : "During electrolysis, copper ions in the solution move to the cathode, where they gain electrons and form a solid copper coating. " 在电解过程中，溶液中的铜离子会移动到阴极，在那里它们获得电子并形成固体的铜镀层。 chemistry electronics physics material science element 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 older televisions, the cathode inside the picture tube shot electrons onto the screen to create the picture. " 在老式电视机中，显像管里的阴极（负极）会发射电子束到屏幕上，从而形成图像。 electronics device technical physics machine energy science 与AI对话词汇游戏阅读练习
noun 下载 🔗分享 阴极，负极 That electrode of a semiconductor device which is connected to the n-type material of a p-n junction. Examples : "In the LED circuit we built in class, the cathode, connected to the n-type semiconductor, was marked with a shorter lead. " 在我们在课堂上搭建的LED电路中，阴极，也就是连接到n型半导体的那个电极，用较短的引脚做了标记。 electronics device technology material physics science 与AI对话词汇游戏阅读练习
