摘　　要：在真空度为10^(-5)Pa的室温条件下,用二次电子发射接触电位差法,测量了用单辊急冷技术制备的Pd_(83.5)Si_(16.5)和Cu_(70)Ti_(30)金属玻璃在晶化转变前后的电子逸出功。结果表明,金属玻璃的逸出功,比相应晶态的高。The work function before and after the crystallization of two glassy alloys, Pd_(83.5)Si_(16.5) and Cu_(70)Ti_(30)prepared by rapid quenching technique with a single roller have been measured by means of the contact potential difference method in the secondary electron field at room temperature under 10^(-5)Pa vacuum. The results show that the work function of two glassy alloys are higher than those of the corresponding crystalline alloys.
