摘要
在DS6×800A 压机上,用NiCr-NiSi热电偶测量出高压腔内铅的熔点,再根据铅的液-固相变曲线得出所对应的压力。在600~-760℃温度范围内,测定出高压腔内压力(1.27~6.62 GPa)与油压的对应关系。对两种不同传压介质腔内压力测定的结果表明,采用 NaCl作内层传压介质后,其传压效果比不用 NaCl 只用叶腊石的情况提高了10%。
Melting points of Pb under high pressure were measured with the NiCr-NiSi thermocouple, using the cubic anvil type high pressure apparatus, so that the rela- tion between pressure in cell and oil pressure was obtained according to the melting curve of Pb in the range from 600 to 760℃ for two assemblies of pressure mediums. The contrast result was clear, that the pressure in the cell was higher about 10%, when NaCl was used as the internal pressure medium than the pyrophylite was used under the same oil pressure.
