| 单词 | 极板 |
| 释义 | 〔farad〕The unit of capacitance in the meter-kilogram-second system equal to the capacitance of a capacitor having an equal and opposite charge of 1 coulomb on each plate and a potential difference of 1 volt between the plates. See table at measurement 法拉：电容的单位，等于电容器极板上充以1库仑电量后两板间的电压为1伏特时的电容 参见 measurement〔dynatron〕A tetrode with grid and plate potentials so arranged that plate current decreases when plate potential increases.负耗阻性管：由栅极和极板电势组成的四极管，其中当极板电流降低时极板电势反而增加〔plate〕An electrode, as in a storage battery or capacitor.极板：蓄电池或电容器中的电极〔antimony〕A metallic element having four allotropic forms, the most common of which is a hard, extremely brittle, lustrous, silver-white, crystalline material. It is used in a wide variety of alloys, especially with lead in battery plates, and in the manufacture of flame-proofing compounds, paint, semiconductor devices, and ceramic products. Atomic number 51; atomic weight 121.75; melting point 630.5°C; boiling point 1,380°C; specific gravity 6.691; valence 3, 5. See table at element 锑：一种金属元素，有四个同素异形体，最常见的是一种硬而脆的银白色发光晶体物质。锑普遍用于各种合金，特别是和铅一起用于电池极板，制造防火合成物、油漆、半导体装置和陶瓷制品。原子序数为51；原子量为121.75；熔点为630.5°C；沸点1,380°C；比重为6.691；化合价为3,5 参见 element |
