Based on the chromatographic detector theory, whether a chemical reaction is a fast reaction or not it can be judged according to the product of peak area and carrier flow rate is a constant or not.

本文运用色谱检测器理论，由峰面积与载流流速的乘积是否为一常数可判断某一化学反应是否为快速反应。

The TDI and internal standard chemicals can be separated better and the side reaction is reduced at lower column temperature by use of SE54 capillary column and FID detector.

选用SE54型毛细管柱、氢火焰离子化检测器，以三氯代苯为内标物，采用较低的柱温，使内标物与TDI更好地分离，减少了副反应的发生。

This paper analyzes the formation of the output wave from a dynamic detector, the relation between the output wave and the magnetic field distribution and the effect of the armature reaction on them.

本文就动测这个侧面，简要地叙述了动测波形的形成及其与气隙磁场分布的关系和电枢反应对它们的影响。

Its reaction with the odour molecules changes a detector's electrical resistance, and this signal is fed into a neural net (the closest that computer technology has got to imitating the pattern-recognising abilities of networks of nerve cells) to work out what is being smelt.

ECONOMIST: Wine-tasting will never be the same again

The resistance of a detector changes as the polymer swells in response to its reaction with the odour molecules and thus alters the connections between the particles of carbon black.
