您要查找的是不是:
- hot cathode x ray tube 热阴极 x 射线管
- The cathode ray tube had just been fitted with a hot cathode,which permitted operation at 300 volts instead of the previously required 10,000,the lower voltage obtainable from a stack of dry cells of less than ceiling height. (那时)刚刚有用一种热阴极作成的阴极射线管,这种热阴极不需要以前要求的10,000伏,可以在300伏电源下工作,这种低电压可以由不再堆得天棚高那末多的干电池来获得。
- Better precision X ray tube, and wider analysis scope, long lifetime up to 10 years. 激发源X射线光管精度更高,范围更宽,使用寿命长达10年以上;
- Cheap EDXRF generally apply cheaper X ray tube, whose lifetime just thousands of hours; high performance EDXRF's lifetime reach up to 10 years. 低端品牌厂商的EDXRF采用廉价的X光管,寿命在几千小时而已;高端的可以使用10年以上(如同家庭使用的荧光灯管或者彩电的显像管寿命)。
