摘要
介绍对核磁共振教学实验所做的一些改进,包括采用均匀、高强度的永久磁铁,设计信噪比高、低功耗的探头以及对每一种样品采用独立探头.这些改进提高了测量精度并使学生能独立完成实验和观察到更多的现象.
Some improvements on the teaching experiment of nuclear magnetic resonance is reported. The improvements include using a permanent magnet with uniform and high field, designing a new detector with high quality factor and low power consumption and using independent detectors for each sample.These measures improve the precision and the students can perform the experiment independently and observe more phenomena.
