每个单位放电产生光电流脉冲。由于许多考虑的结果，人们发现，铝在钢中已经能够确定金相;铝在均匀状态（酸溶铝在化学分析）和不均匀的一个（不溶铝）分别。从积分光电流脉冲的分布中获得了用于金相分析的有效和适当的信息。该分布通过以下技术获得。每个单位放电产生的脉冲经过适当的整形和放大后，必须经过多道脉冲幅度分析电路。在P. H.一、输出脉冲幅度显示了由于样品中Al的金相状态而引起的分布。中值表示T。在火花时间内，中间值的移动显示出不稳定。样品中的Al。在此方法中，所获得的结果为0.0015%Al（铝）（在0·~ 0.05%Al范围内）。Al和0.0018%Al（铝）（在0·`0.04%Al）的溶胶。分别。
photo-current pulses occured from every unit discharge. As the result of many considerations, it was found that Al in steel has been able to be determined metallographically; Al as in the homogeneous state (acid-soluble Al at chemical analysis) and as in the inhomogeneous one (insoluble Al) respectively. The efficient and appropriate informations used to the metallographic analysis was derived from the distribution of integrated photo-current pulses. This distribution was obtained by the following techniques. The pulses occured from every unit discharge were shaped and amplified suitably and must be put through multi-channel pulse height analyzer circuit. After treatment in P. H. A., the output pulse amplitude shows the distribution due to the metallographical state of Al in the sample. The median value shows T. Al , and the shift of the median values during spark time show insol. Al in the sample, respectively. In this method, the results obtained are 0.0015% Al (ƒÐ) (at the range of 0•`0.05% Al) for T . Al and 0.0018% Al (ƒÐ) (at 0•`0.04% Al) for sol. Al respectively .
