三○一七厂参照中国科学院应用化学研究所及冶金部三○一厂的经验,並结合本厂的实际情况,装制成功了一台AJZ—1型光电直读仪,已用于铸铝车间炉前、炉后的成分分析(图1)。该仪器由中型石英摄谱仪改装而成。在中型石英摄谱仪的暗盒部位加装了一个“光电头”,内有12个石英出射狭缝,只允许被预先选定的待测元素光谱的特定波长通过。此待测信号被光电倍增管所接收。然后将其光电流送至积分系统积分。在采用“自动曝光”的情况 3171 Factory Reference Chinese Academy of Sciences Institute of Applied Chemistry and the Ministry of Metallurgical Industry 301 Factory experience, combined with the actual situation of our factory, a successful installation of a AJZ-1-type optical direct reading instrument has been used for aluminum Workshop furnace, furnace composition analysis (Figure 1). The instrument is converted from a medium-sized quartz spectrograph. A “photoelectric head” has been added to the cassette portion of a medium quartz spectrograph with 12 quartz exit slits that allow only specific wavelengths of the preselected spectrum of the element under test to pass through. The signal under test is received by the photomultiplier tube. The photocurrent is then sent to the integration system integral. In the use of “automatic exposure” situation
