摘　　要：在合成人造金刚石过程中,发生“放炮”现象前,外围的加热体会发生变形。通过分析加热体变形导致的电阻及电流变化,可以有效预警“放炮”现象。通过仿真模拟计算分析加热体变形引起的电流变化,并根据生产实际的统计学结果制定预警方案。将预警方案应用于生产中实现了预期效果,可有效避免此类事故,降低生产成本。In the synthesis of man-made diamond,the surrounding heating material would deform before the ultra-high pressure leakage occurs.The change of resistance and current,caused by the deformation,was analyzed to warn about the leakage.The current change was simulated and calculated by models,and an early warning scheme was formulated according to the actual statistics.The scheme,when applied in production,would achieve its expected effect,thus effectively avoiding such accidents and reducing the production cost.
