This makes sense for the reason that temperature oscillations or oscillating emissions from the metal surface often occur which would cause the infrared detector to trigger when it was not wanted.

这使得因为从表面温度振荡或振荡金属的排放量往往发生会导致红外探测器触发时，它不想要的感觉。

Similarly, we can't sense radioactivity without a radiation detector.

同样，如果不用辐射探测器，我们也不能感觉到放射现象。

Aiming at urgent requirement of drilling leakage zone in real time measurement, the development of wireline downhole leak detector has prodigious practice sense.

针对实时测量钻井漏失层位的迫切需要，研制电缆式井下测漏仪具有很大的实际意义。
