Uncooled bi-material infrared detectors have the potential of approaching the theoretical limit of noise equivalent difference in temperature because of its high sensitivity and low noise.

非致冷双材料室温红外探测器具有高响应率和低噪声的特点，噪声等效温差接近理论极限。

Meanwhile, by the influence of water vapor in the process of heating, the gradient of equivalent potential temperature weakened, and baroclinic term also declined, so the total MPV increases.

同时，在此过程中受水汽加热的影响，水平相当位温梯度减弱，负的斜压项减弱，使得总的湿位涡正值增大。
