polymineral meaning in Chinese

多矿物

The experiments of anomalous fading , preheat and the effect of prior - ir exposure on osl stimulated by blue light in polymineral fine grains , indicate that the post - ir osl signals do not show detectable fading , and has greater thermal stability
黄土细颗粒样品的反常衰退实验、预热实验和红外暴露实验都表明， post - irosl信号热稳定性好。
It must be noted here that blue stimulated luminescence from polymineral fine grains presumably originate from both quartz and feldspar grains , and it is thus likely that any blue stimulated signal following an ir exposure in our samples will be richer in quartz osl in comparison to a pure blue stimulated signal without ir exposure
Blsl信号由两部分组成，一部分既可以被蓝光激发，也可以被ir激发，另一部分只能被蓝光激发，这两种类型的陷阱在不同的预热温度中分布不均匀。
