摘要:

对电子辐照石墨-金刚石转变进行了能量估算。本文解决了在石墨圆柱内放置脉冲周期性能量源时合成金刚石的热传导问题,得到了温度和压力随时间的变化关系,表明在电子轰击下石墨内的温度和压力足以使石墨转变为金刚石。

英文摘要:

The energetic evaluations of graphite-to-diamond transition by electron irradiation are performed. The heat conduction problem is solved for the diamond synthesis when a pulse-periodic source of energy is located within a graphite cylinder; time dependences of temperature and pressure are found. It is shown, that the temperatures and pressures implemented in graphite are sufficient for graphite-to-diamond transition under electron bombardment.
