| 单词 | 电子元件 |
| 释义 | 〔subcomponent〕A portion of a component, especially a piece of electronic equipment that can be incorporated into a component of a larger unit; a subassembly:亚元件：元件之一部分，尤指能装配于一更大单位的元件上的电子元件；分组合件：〔patch〕To connect temporarily (electronic components), as with a patch cord.（临时）连接：用接线把（电子元件）临时性地连接起来〔thermocouple〕A thermoelectric device used to measure temperatures accurately, especially one consisting of two dissimilar metals joined so that a potential difference generated between the points of contact is a measure of the temperature difference between the points.热电偶：用于准确测量温度的热电子元件，尤指一个热电子元件，由两种连在一起的不同金属组成，这样连结点间产生的电压变化就是两点间温度差异的量度〔tungsten〕A hard, brittle, corrosion-resistant, gray to white metallic element extracted from wolframite, scheelite, and other minerals, having the highest melting point and lowest vapor pressure of any metal. Tungsten and its alloys are used in high-temperature structural materials; in electrical elements, notably lamp filaments; and in instruments requiring thermally compatible glass-to-metal seals. Atomic number 74; atomic weight 183.85; melting point 3,410°C; boiling point 5,900°C; specific gravity 19.3 (20°C); valence 2, 3, 4, 5, 6. Also called wolfram See table at element 钨：一种坚硬、易碎 、耐腐蚀的金属元素，颜色从灰到白，主要从黑钨矿、白钨矿和其它矿物中提取出来，它是所有金属中熔点最高，气压最低的金属。钨及钨合金可用于耐温的建筑材料；电子元件，主要是白炽灯丝；以及要求热度上兼容的玻璃至金属的密封装置的仪器。原子序数74；原子量183.85；熔点3,410°C；沸点5,900°C；比重19.3(20°C)；原子价2,3,4,5,6 也作 wolfram 参见 element |
