Magnetization curves of the polycrystalline Fe-Co and Ni-Co alloys of the cubic system and also of the pure cobalt were determined by means of a ballistic method. Gans' theory of the magnetic properties of isotropic ferromagnetics was applied. The agreement between his theory and the experimental results is quite good for the strong fields but not so for the weak fields, just as in the ease of the pure ferromagnetics. The discrepancy for the weak fields may be explained by his neglect of the free energy which is required to magnetize the elementary crystals isothermally to the saturation intensities in the easy direction of magnetization. After including this part of the energy the agreement between theory and experiment is improved in general and in some cases, it is remarkably good. For pure cobalt the magnetization intensities for a given field are smaller than those obtained by previous investigators, but in better agreement with the theory than those previously obtained. Since the disagreement cannot be accounted for by the experimental error in the present investigation, the comparatively less studied cobalt needs further investigation.

用冲击法量属於正方晶系之铁钴及镍钴合金并钴之多结晶体之磁化曲线与Gans氏各向同性铁磁物质磁性之理论相较知在强磁场时理论与实验之契合甚佳在弱磁场时则较差,弱磁场时之差异,可以Gans氏计算时略去磁化各元晶体於其易磁化方向至饱和度所需之自由能一点解释之改正此点后理论与实验之契合大体改善在数种合金且极佳。钴之磁化强度在各磁场下较之前人所得者均小,惟与理论之契合则较佳:此与前人不同之点既不能归诸本实验之误差,则此较少被注意之钴实需要更进一步之研究

A spectrographic procedure for determining copper in concentrated iron ores has been worked out for routine analysis. The powder method is found to be satisfactory with a medium quartz spectrograph and an activated a. c. arc between carbon electrodes as light source. In order to minimize erratic burning of the sample, the electrodes are pre-burned for one minute and then loaded with a mixture of equal weight of the ore sample and carbon powder. The analysis pair of lines chosen are: Cu 2824.369- Fe 2824.67 for copper contents ranging from 0.05 to 0.3%, and Cu 2824369- Fe 2828.813 for those between 0.3 and 1.0%. The results obtained spectrographically have been checked by wet chemical analysis, amongst 110 samples 80% of which the two methods checked within 0.02%.

我们尝试用光谱的方法协助解决分析大量铁矿精矿试样中微量铜(O.05-0.1%)的问题。采用了交流电弧碳电极粉末法,应用现有的设备(中型光谱仪、不碳电极、质量低的照相板)进行试验,找出了比较适当的激发条件和分析线对。把空白碳电极加以预燃并在铁矿试样中搀入适当分量的碳粉,可以基本上消减样品在燃烧中的喷爆现象。根据样品的燃烧曲线的研究,选择了适当的曝光时间,使分析的结果不受样品所含铜的化学组成状态的影响。 所选定的分析线对当含铜量在0.05-0.3%的范围内时是Cu2824.369-Fe2824.67,当含铜量在0.3-1.0%的范围内时是Cu2824.369-Fe2828.813。根据所得的两条定标曲线作了110个样品的分析,光谱分析结果与化学分析结果的差值在0.02%以下的约占分析样品总数的80%左右。关于含铜量为0.05-0.3%的样品,光谱分析已经可以代替化学分析,并节省大量的人力和物资。
