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。

The necessary condition of external oscillations is the existence of closed geodesic lines on the surface of scatterers.
外部振荡存在的必要条件是散射体表面有闭合测地线。

Distributions of monthly sea surface temperature (SST) anomaly field over the equatorial Pacific and the northern Pacific have short-term climatic oscillations in the past 40 years.
