地震监测台
<p>近日，我国在世界最高峰建成了首个无人值守地震台。珠峰地震台的建成填补了西藏日喀则南部地区的监测空白，增强了我国中尼边界地区的地震监测能力，还将为地学工作者提供这一区域的第一手地震观测资料，将大大增强我国在青藏高原国际地学和防震减灾领域的科技竞争能力。</p><p><span word="China">China</span> <span word="has">has</span> <span word="built">built</span> <span word="its">its</span> <span word="first">first</span> <span word="unattended">unattended</span> <span word="seismic">seismic</span> <span word="monitoring">monitoring</span> <span word="station">station</span> <span word="at">at</span> <span word="the">the</span> <span word="foot">foot</span> <span word="of">of</span> <span word="Mount">Mount</span> <span word="Qomolangma">Qomolangma</span>, <span word="the">the</span> <span word="world">world</span>'<span word="s">s</span> <span word="highest">highest</span> <span word="mountain">mountain</span>.</p><p>我国在“世界屋脊”珠穆朗玛峰脚下建成了首个无人值守地震台。</p><p>在上面的报道中，<span word="seismic">seismic</span> <span word="monitoring">monitoring</span> <span word="station">station</span>是“地震监测台”，简称“地震台”。地震台是利用各种地震仪器进行地震观测的观测点，是开展地震观测和地震科学研究的基层机构。这次建成的地震台是<span word="unattended">unattended</span> <span word="seismic">seismic</span> <span word="monitoring">monitoring</span> <span word="station">station</span>(无人值守地震台)，<span word="unattended">unattended</span>在这里表示<span word="not">not</span> <span word="watched">watched</span>(无人看守的)意思，有时还表示<span word="neglected">neglected</span>(被忽视的)意思，比如：<span word="Never">Never</span> <span word="leave">leave</span> <span word="your">your</span> <span word="luggage">luggage</span> <span word="unattended">unattended</span>.(千万注意看好你的行李。)</p><p><span word="Seismic">Seismic</span>一词的意思是“地震的，地震性的，地震引起的，易发生地震的”，和它相组合的短语都和地震有关。例如：<span word="seismic">seismic</span> <span word="waves">waves</span>(地震波);<span word="seismic">seismic</span> <span word="focus">focus</span>/<span word="origin">origin</span>(震源);<span word="seismic">seismic</span> <span word="zone">zone</span>(地震带);<span word="seismic">seismic</span> <span word="catastrophe">catastrophe</span>(地震灾难)。</p><p>地震台中不可缺少的就是地震勘探(<span word="seismic">seismic</span> <span word="prospecting">prospecting</span>)的工具——地震仪(<span word="seismograph">seismograph</span>)，通过它可以测量地震活动度(<span word="seismicity">seismicity</span>)和地震波速(<span word="seismic">seismic</span> <span word="velocity">velocity</span>)。</p>
