The heat diffuse can be considered as temperature oscillation under limiting damp, as well heat can be transfersed by the wave way.
热扩散可以被看成是一种极限温度阻尼振荡问题;而热可以以波动形式传输。

The frequency-domain NIRS instruments modulate the light with a RF sine wave, which generates diffuse photon density wave (DPDW) in turbid tissue like brain.
