| 摘 要： | 本谱仪具有积木式结构,采用超再生振荡检波、销相放大电路,以及场效应管和集成器件.它可用于探测氯化物样品中(35)~Cl和(37)~Cl谱线,已在高年级的实验课中使用两年.由于目前国内还没有这种商商品仪器,这类实验也尚未普及,故本文着意于学生的培养和训练,主要阐述仪器的制作和实验方法.

| Abstract: | This paper aims to describe the manufacturing process of a NQR-Spectro-meter and its use for training studencs in lab work.
Modelled on the structural pattern similar to that of the building blocks and using FET and IC and such units as the superregenerative oscillator and phase-locked amplifiers, this nuclear quardruple resonance spectrometer functions as a detector for tracing 36Cl and 37Cl resonance lines in chloride samples. Used for two years in senior classes of the Physics Department, it has proved successful both as a lab device and as a means in training students in lab work. |

| Keywords: | superregenerative oscillator-detector self-quenched critieal coherent state phase-locked amplifier the second differential curve of NQR signals |
