NF3-specific detectors are highly recommended since NF3 has no detectable odor.
由于NF3没有可探测到的气味,强烈推荐使用NF3专用探测器。
The particles can be detected with a condensation nucleus counter.
这种粒子可以用凝结核计数器探测到。
the detected micrometeoritic material.

It is earth's eye; looking into which the beholder measures the depth of his own nature.
它是大地的眸子,观察它的人可以探测到自己天性的深度。
Because photometers can detect tiny decreases in the brightness of a star, the craft will be able to discover planets as small as Earth.
因为探测船上的光度计可以侦测到恒星亮度的微小变化,便可发现和地球一样小的行星。
get on sounding

Even if you start with something (like a bump on a rotating neutron star) that gives off a perfect sine wave signal, it won't stay that way by the time it gets into the data stream.
即使你开始时探测到一个完美的正弦波信号,等到记录它的时候可就是另外一个样子了。
Unmanned probes are not going to reach the stars within this century.
本世纪内,无人驾驶探测器不可能到达恒星。
A variety of subsurface geometrical configurations are found in nature, and a great number of tools are available for their exploration.
在自然界可找到各种地下几何轮廓,对于它们的探测有许多手段可用。
(neurophysiology) rapid fluctuations of voltage between parts of the cerebral cortex that are detectable with an electroencephalograph.

Humans possess no senses that can detect the presence of nitrogen.
人类没有能够探测到氮的存在的官能。
Humans possess no senses that can detect the presence of helium.
人类没有能够探测到氦的存在的官能。
NF3 has no detectable odor, so forced air/exhaust ventilation and ambient air monitoring are recommended where NF3 is stored or used.
NF3没有可以探测到的气味,所以推荐在储存和或使用NF3的地方采用强迫通风/排气通风。
This expansion should improve our ability to study natural lightning as well as triggered lightning and should increase the odds of detecting more gamma-ray bursts from the thunderclouds.
扩充后应可提升我们研究自然及人造闪电的能力,并增加从雷雨云探测到γ线的机会。
If you've ever thought about digging a hole to China, a new Japanese ship might be your best bet.
如果你曾经想过从地底钻个洞直接通到美国,那么,日本有艘探测船可能会是你最棒的选择。
