线状光谱

光学滤光片是从连续的光谱中提取一定宽度的光谱带或在离散的线状光谱中提取某些辐射的光学元件。

Optical filters are spectrum instruments which are used to intercept the spectrum band with a certain width from the continuous spectrum or extract some radiation lines from line spectrum .

在DDT中间阶段辐射已比较强，既有原子线状光谱，也有分子带状光谱以及热辐射背景；

In the middle process of the DDT , the emitted light became strong and the spectra observed consisted of line spectra of atoms , band spectra of molecules plus continuous spectrum of the thermal radiation ;

二次冲击压缩氩气的辐射信号上升前沿的时间分辨光谱用OMA系统记录，并观察到450nm附近有较强的发射光谱带，但没有观察到明显的线状光谱。

The time resolved spectra in the rising front of the radiant signal in the re shocked argon were recorded by means of an OMA , and strong emissive spectrum bands near 450 nm light wave length but no linear spectrum were found .

实验结果表明，氮气激光等离子体光谱由较强的连续光谱背景和迭加在其上的若干线状光谱组成。

The preliminary results show that all the spectra consist of a strong continuous background and some line spectra .
