| 英文摘要: |
| In order to satisfy the demand of good performance of detection at 340 nm ultraviolet light Spectrum, the authors design a preamplifier circuit of photoelectric detector. Moreover, through theoretical analysis and computer simulation the authors also propose a universal method of the designation of photoelectric detector's preamplifier which can achieve high stability and high speed. Results of the experiment prove that the circuit we design can detect 340 nm ultraviolet light spectrum fairly well and achieve a fairly high precison. |
