symmetry of peak

This system helps to obtain all the physical characters of the beam in any section plane, such as FWHM, penumbra, peak value, symmetry and homogeneity.

利用该系统可以实时、直观地获得加速器束流强度的相对分布曲面，给出任意剖面的束流强度分布曲线和FWHM、半影、峰值、对称度、均整度等参数。

Both parts are combined by a capillary column connector. The separation principle for polar compounds was studied according to the separation efficiency ( such as the peak symmetry, width and retention time) of three groups of model compounds separated by six coupled columns with different polarities.

通过三组模型化合物在六种不同极性串联组合柱中的分离效果（包括色谱峰的对称性、峰宽、保留能力等），来研究串联柱对极性化合物的分离原理。
