检测相同质量玻璃样品在谐振腔不同位置的电子顺磁共振(EPR)信号强度和,Q,因子,以及EPR信号强度和,Q,因子随质量增加的变化趋势。结果表明,随着距谐振腔中心长度的变化,EPR信号强度的变化呈正态曲线型:样品在谐振腔中心位置时,EPR信号强度最强,并以此为轴,两侧距离中心越远,信号敏感度逐渐下降,EPR信号强度则越小;谐振腔≥4 mm或≤-4 mm处的EPR信号开始严重失真;相比正向位置的EPR信号强度和,Q,因子,负向对称位置的结果均偏高;质量增加,EPR信号强随之增加,单位质量EPR信号强度也缓慢增加,但100 mg左右达到饱和;,Q,因子随质量增加而减小,随不同位置、不同方向而有所变化。兼顾信号强度、信噪比最大化与质量效应、位置效应最小化,得出最优检测位置为谐振腔中心(±2mm),最佳样本质量则应≤100 mg。
The paramagnetic resonance spectroscopy technique was used to detect the electron paramagnetic resonance (EPR) signal intensity and ,Q,-factor at different positions in the resonant cavity of a glass sample, as well as with increasing glass mass. The results showed that the signal intensity at various distances from the center of the resonant cavity follows a normal distribution:at the center of the resonant cavity, the signal intensity was the highest, while the farther away from the center, the lower the signal sensitivity and the smaller the signal intensity. Serious signal distortion started at ≥ 4 mm or ≤ -4 mm from the center, and the signal intensity and ,Q,-factor at negative positions were higher than those at the positive symmetry positions. The signal intensity increased with increase in the glass mass, reaching saturation at approximately 100 mg. The ,Q,-factor decreased with increasing mass and changed with different positions and directions. Therefore, taking into account the maximization of signal intensity and signal-to-noise ratio, and minimization of mass and position effects, the optimal detection position is at the resonant cavity center (±2 mm), with the best sample mass ≤ 100 mg.
