探测者

And to make sure this light lasts, they installed a motion sensor that detects when a human or sewer rat is near.

而且为确保这个灯持续发光，设计人员安装了一个行踪探测器，可以探测出附近的不怀好意者或者是阴沟老鼠。

When a coherent light is scattered by the rough surface, the scatted light forms a granular intensity distribution known as speckle. Speckles are coherent superposition of the light scatted by the rough surface. Therefore, speckles carrier some information of the rough surface.

相干光从光学粗糙表面散射时，结果在探测面上出现随机的颗粒状的强度分布，称为散斑，散斑是由粗糙表面上各面元的散射光波之间的干涉在空间域内形成的，所以散斑也是粗糙表面一些信息的携带者。

Though the dangers of mapping a previously unexplored cave far outweigh the bite of this spider, one caver admits, their bite is bad, but nobody has died from one.

尽管探测一个从未开发过的洞穴远比被这种蜘蛛咬一口的危险性大得多，但一个探察者说：被这蜘蛛咬了可不太妙，但还没人因此而死。

Researchers used cell-phone-like tracking devices, for example, to record the Arctic migration of narwhals, a whale with a long twisted tooth, and remotely operated submersible s to reach several kilometers down into the oceans to study delicate marine animals that are impossible to collect.

例如，考察者们使用电话式的跟踪器记录北极角鲸的迁徙，角鲸是带有一个很长的牙齿，从很远的地方就能探测到海洋里几千公里去研究那些不可能收集到的海底动物。

"While this result is consistent with dark matter,it is also consistent with backgrounds,"said Fermilab Director Pier Oddone.In 2010,the collaboration is installing an upgraded detectorat Soudan with three times the mass and lower backgrounds than the present detectors.

&即使此次的结果跟暗物质一概，它同时也跟布景一概，&费米尝试室的主任Pier Oddone说道：在2010年，切磋者们将会在Soudan安置一个进级了的探测器(超级CDMS，SuperCDMS)，比此刻的探测珍视3倍，而噪音水平更低。

Searching for a terrain similar to that found on Mars, the team took the rover to El Teide National Park in Tenerife.

为了寻找与火星相似的地形，探测队将漫游者带到位于特内里费的El Teide国家公园。
