The effect of sample self absorption, selective reflection, temperature, sample grain and liner on FT IR radiation spectrum are discussed.
讨论了样品的自吸收效应，加热温度、选择性反射带和粒度以及衬底等物理条件对红外辐射光谱的影响。
A reduced sample grain size will result in a strong oxidation, thus the KBr disc technique for infrared spectroscopic analysis requires a strict control of the sample grain size.
样品粒径减小会导致样品严重氧化，因此压片法红外光谱分析要严格控制样品粒径。
I managed to take one optically stimulated luminescence (O.S.L.) sample at the suspected delta, as well as a few samples for grain size analysis.
我试着在怀疑是三角洲的地方带一个光释光样本，并带一些样本用于晶粒尺寸分析。
