摘　　要：本文采用非恒压力加压和非恒功率加热的控制技术,设计了金刚石合成工艺曲线。该工艺合成金刚石时,能明显提高合成腔体内的温度场与压力场的稳定性,改善金刚石单晶生长环境,可使（?）30mm腔体合成金刚石的单产增加9.69％,MBD8以上品级的单晶同比增加41％。This paper suggested a technological process curve on synthetic diamond by utilizing the condition of non-constant electrical power and non-constant pressure. The result demonstrated that the technique can increase the stability of temperature and pressure in synthetic zone and improve the growth condition of diamond single crystal. And it also increases 9. 69% output of diamond. In 030mm chamber diamond yield of MBD8 can be increased by 41% .
