摘要
激光脉冲技术在材料热物理性能测试方面已得到了广泛的研究和应用。本文以 Parker模型为理论依据 ,在激光热导仪上建立了计算机数据采集、处理系统 ,并运用激光脉冲法 ,成功地测定了不易焊接的金属材料和半透明陶瓷材料的热扩散率、比热和导热系数。
The laser flash technique has been widely studied and used for measurements of thermophysical properties. Based on Parker model, a computer system was established for automatic data sampling and processing. Using laser flash method, thermophysical properties of difficult welding metals and translucent ceramics were successfully measured.
