求翻译：本文介绍串联式火焰-石墨炉一体的原子吸收分光光度计的结构特点，对如何提高由于光路延长带来的能量降低问题做了重点探讨。通过在4600原子吸收分光光度计上的实际测试,证实:光路和电路的优化设计，可使紫外区能量得到提高。对砷元素（As193.7nm）进行重点测试，考核了边缘能量、线性及特征量、精密度的指标，验证结果令人满意。是什么意思？

This article describes one of series flame-graphite furnace atomic absorption spectrophotometer structural characteristics, on how to improve due to the energy of the light path extension brings lower did focus on the problem. Through actual testing on the 4,600-atomic absorption spectrophotometer, confirmed: optimum design of optical circuits and may improve energy in the ultraviolet region. Arsenic (As193.7nm) focus test, check the edge energy, linear and characteristic quantity indicators, precision, verify that the results are satisfactory.
