In-situ Raman spectra of olivine have been studied at temperatures 273 K to 1 113 K and at ambient pressure using resistance-wire heating. Temperature of the sample was measured by an alumel-chromel thermocouple. 利用微型电阻丝加热装置产生高温,采用镍铬热电偶探测样品的温度,在273~1113K温度范围,对橄榄石晶体进行了原位高温拉曼光谱研究。
Results on chromel and lead are presented. 给出了镍铬和铅的测量结果。
Each element is consisted with a graphite block and a chromel~ alumel. 每个量热器单元是由石墨块与镍铬&镍铝热电偶构成。
Chemical constituent and dynamics properties of the weld seam metal have reached the requirements of the same kind of chromel welding core stainless steel electrode. 焊缝金属化学成分、力学性能达到同类型铬镍合金焊芯不锈钢焊条的要求。
