光声光谱适于研究不透明、高反射、高散射的稀土色剂和釉瓷的光学性质。

Photoacoustic spectroscopy (PAS) is a new technique to study optical properties of rare earth pigments and glazed tiles, which are non-transparent, highly reflective and scattering.

你能够正确地减慢中子，通过将它们散射，用一个恰当的，慢化剂，这样它们就不会损耗或者被吸收。

And that you can appropriately slow down the neutrons by scattering them with an appropriate moderator such that they're not lost or absorbed.

在初步的人体研究中，我们也观察到了同样的心腔内造影剂后向散射强度的变化规律。

In human studies, we also observed same intracardiac cyclic changes of backscatter from hydrogen peroxide microbubbles.
