您要查找的是不是：
- cesium fountain clock 铯喷泉钟
- ASIDE FROM ITS REPLACEMENT of cesium with rubidium, RACE will be a fairly standard fountain clock, with lasers cooling the atoms but microwaves kicking the electrons around and ticking off the time. 除了以铷取代铯外，RACE其实是相当典型的喷泉钟：以雷射冷却原子，而以微波激发电子并计时。
- The low temperature all but eliminates relativistic and Doppler shifts, and it gives a two-meter-tall fountain clock half a second to flip the atoms' spins. 这样的低温几乎消除了相对论及都卜勒效应引起的偏移，使一个两公尺高的喷泉钟有半秒钟的时间来反转原子的自旋。
- Blackbody ac Zeeman shift at room temperature is calculated to be of 10-15 order, thus should be corrected for the cesium fountain frequency standard in determining the accuracy of the standard. 结果表明: 1) 室温下黑体辐射塞曼频移可达10-15量级, 在评定铯原子喷泉频标准确度时, 需要对此项频移加以修正;
- Cesium atomic fountain clock 铯原子喷泉钟
- Design for Microwave Cavity in a Laser-Cooled Rb Fountain Clock 激光冷却铷原子喷泉钟的微波谐振腔设计
- She dabbled her hands in the fountain. 她把手伸到喷泉中玩水。
- I didn't wake up until I heard the alarm clock. 直到听到闹钟的铃声我才醒来。
- That clock is a family heirloom. 那个座钟是祖传下来的。

- He is rooting about for his fountain pen. 他正在寻找他的自来水笔。
- I'm wild about losing my gold fountain pen. 我因遗失了自来水金笔而暴躁不安。
- I set it by the clock on the railway station. 我是按火车站的大钟对的。
- She dabbled her fingers in the fountain. 她用手指在喷泉中玩水。
- The clock ticks louder and louder in a quiet room. 钟的滴答声在静静的房间里变得越来越响。
- The grandfather clock was back in its old place. 落地式大摆钟已放回原处了。
- The little clock tinkled out the hours. 那只小钟叮叮当当地报时。
- Blood is pumping out of his belly like a fountain. 血像喷泉似地从他的腹部涌出。
- Let's set the clock by the radio time signal. 咱们照着收音机的报时信号把钟对一对。
- Closing time at this pub is eleven o' clock. 这酒馆的打烊时间是十一点。
