The threshold temperature has been substantially underestimated in previous studies.

科学家们表示：“实际上，以往的研究低估了临界温度。

The wave velocity, permeability and porosity of rocks changed obvious around the threshold temperature.

在阈值温度附近岩石波速、渗透率和孔隙度变化幅度最大；

Therefore, there is always a difference between the medium temperature and the threshold temperature of the infrared detector.

因此，总有媒体之间的温度和红外探测器的门槛温差。

Under global warming, it turns out that the threshold temperature goes up too.

Well, the magical moisture-absorbing material may get even better, as the plan is to increase the amount of water the material can hold and lower the temperature threshold for its release.

Many low-lying nations have used the UN conference, which is currently under way in Doha, to call for a threshold temperature rise less than 2C, arguing that even a 2C rise will jeopardise their future.
