查询词典 melting point

These materials have excellent chemical and thermal stability, high melting point, high thermal conductivity, high breakdown voltage and large carrier mobility rate especially the smaller electron affinity and potential or even a negative electron affinity, and the situation has greatly reduced the market launch of the threshold voltage, therefore, Field emission of such material will have a very vast potential for development and application prospects.

这些材料具有良好的化学与热稳定性、高熔点、高热导率、高击穿电压及大的载流子迁移率，特别是较小的电子亲和势甚至是负的电子亲和势，大大降低了场发射的阈值电压，因此，这类场发射材料将有着极为广阔的发展潜力及应用前景。
