Following the development of the copper cup-electrode solution method for the spectrogra-phic analysis of open-hearth slags,a series of experiments was carried out to study the volatili-zation process in such a spectral light source.The correlation of the different volatilizationcurves obtained with different experimental conditions revealed that the volatilization processmay be considered as of two stages.The first stage corresponds to the appearence of the firstpeak on the volatilization curve,where no fractional distillation was observed.It means thatduring this stage,volatilization of the substances into the radiating vapor comes directly fromthe surface of the solution.The second stage corresponds to the appearance of a second peakand the shape and position of this peak is very sensitive to the slight variation of experimentalconditions,which also vary differently for various elements.This tendency toward fractionaldistillation may be directly correlated with the different electrode potentials of the elements.Thus,we regard that the volatilization of the elements,during this stage,into the arc columnis essentially from the inner electrode of the cup.Because of these characteristics of thevolatilization process cited above,substances that do not dissolve in the sample solution can alsoenter into the radiating vapor especially during the first stage from the turbulent solution.Aset of experimental data indicates that the precision of spectral analysis and the position of thecalibration curves are not obviously affected by the fact that open-hearth slags do not alwayscompletely dissolve in an acid solution.The effect of the solvent(HNO_3 and HCl)on the slope of the calibration curves and theinfluence of the anions on the density of the spectral lines of the different analyzing elementswere also briefly studied.Taking into account of the results obtained from the study of the volatilization process of sucha spectral source,we were able to eliminate shifts of the calibration curves in routine analysisof open-hearth slags.This was accomplished by strict control of the height of the surfaceof the solution inside the cup-electrode and careful workmanship of the lower inner electrode.The relative arithmetic mean error of nine independent analyses for all the elements analyzed inslags was within 4%.Preliminary experiments show that this method is also applicable tospectrographic analysis of blast-furnace slags and magnesia.

根据杯形铜电极溶液法用于平炉渣光谱分析所得的初步结果,进行了一系列有关杯形电极溶液电弧光源中燃烧过程的系统试验。在不同情形下测定了溶液中各元素的燃烧曲线,看到曲线上先后有两个高峯出现,因而认为光源中的燃烧过程有两阶段,物质在这两燃烧阶段中进入放电区的方式不同。第一阶段相当于第一高峯出现的期间,在这时并没有分馏现象,这表示溶液中的物质主要是经过溶液的翻腾作用而直接从液面进入放电区的。燃烧过程的后一阶段相当于曲线上的第二高峯的部分,这个峯的形状和位置对于不同元素和不同实验条件很灵敏,有分馏现象出现。根据对于各种分析元素的分解电压,可以认为,溶液中的物质在这个燃烧阶段主要是通过电极心而进入弧柱的。在平炉渣的实际分析中,严格地控制杯中液面的高低和铜电极心的加工规格,所得到各元素的九次独立分析误差都在4%以内。

In this paper, the epicentral distributions of small and moderate earthquakes previous to 9 great earthquakes (M ≥ 7.0) occurred in North China have been analysized. It can be seen that most of these earthquakes are preceded by gaps in the surrounding regions of their epicenters. The relations between the parameters of the seismic gaps such as the lengths of their long and short axes, the areas of the gaps etc. and the parameters of the corresponding earthquakes are discussed.
