Under the dual pressure of saving energy and keeping good indoor air quality, scientist all over the world, especially European scientist, start to survey the natural ventilation technique over again.
The technique makes use of dualenergy X-ray imaging, where overlapping tissue signals can be isolated and quantified by exploiting the change in X-ray attenuation at different energies.
这项技术通过双能X-射线成像,重叠的组织信号可以被隔离,并利用不同能量的X射线的改变衰减量化。
