The system is composed of polysilicic ions and polyaluminous ion s with the participation of polyaluminous ion s, the Si-O specific line which is inherent in the examination of infrared spectrum is gradually reducing and becoming a broad belt, the non-ion bond reactions between polysilicic ion and polyaluminous ion is proved by observasion with electron microscopy.

稳定胶体态的硫硅聚铝和氯硅聚铝是性能优良的絮凝剂，体系中含有聚硅离子和聚铝离子。红外光谱测试固有的Si—O特征峰随聚铝离子的引入逐渐衰减，变成较宽的带，聚硅离子与聚铝离子间存在着一种非离子性的健合作用，电镜摄像观察证实了这一结论

It is found that,in a first-order differential Raman spectrum,almost all noise peaks are confined within a narrow horizontal band-like region with the base line going through its middle,whereas thesignal peaks shoot up and down much far beyond the region.Based onthis property,a new peak searching method with the aid of first-order differentiation is suggested.In this paper,a R_spectrumpeak labelling program for SPEX 1403 laser spectrometer with DMIBcomputer is reported.The result of peak labelling sho...

作者提出了用一阶导数谱辅助求 Raman 光谱峰值的新方法，较好地解决了谱峰与噪音的识别问题；编制了 SPEX_(1403)激光 Raman 光谱的标峰程序，具有10种不同大小尺寸的绘图功能、9种不同的字号供标峰选用，操作分为自动、半自动和手动三种方式，具有用于图注、实验条件说明的打字，存、取及复制标峰谱图等功能，克服了一般标峰过程中常见的弊病，标峰效果满意。
