Abstract: An 《HC-4》 CW-NMR spectrometerr for the measurement of the multi-nuclei broad-line in the solid state was designed and manufactured. The scanning and accumulation of the spectra is controlled by the Apple-Ⅱ microcomputer. The home-made cross-coil probe and magic-tec probe together with the high-temperature device is equipped, and then it enables the spectrometer to held excellent sensitivity and wide applicatioa The spectraometer is appropriate to measure non-proton NMR spectra in solid state and dynamic NMR spectra. The whole construction and performance of spectrometer are described in this paper. The sectional specification and some test results aer also given.
