Abstract: Taking advantage of the HL-2A experimental data, an energy confinement database facing ITERL DB2.0 version has been originally established. As for this database, a world widely used statistical analysis system(SAS) has been adopted for the first time to analyze and evaluate the confinement data from HL-2A and the research on scaling laws of energy confinement time corresponding to plasma density is developed, some preliminary results having been achieved. Finally, through comparing with both ITER scaling law and previous ASDEX database, the investigation about L-mode confinement quality on HL-2A and influence of temperature on Spitzer resistivity will be discussed.

Key words: Energy confinement scaling law, Statistical analysis system(SAS), Confinement database

摘要： 利用HL-2A装置实验数据，初步建立了面向ITERL DB2.0版本的能量约束数据库，采用了统计分析系统(SAS)对HL-2A约束数据进行了分析和评估，开展了能量约束时间对密度的定标律研究，并得到了初步结果。最后通过与ITER定标律和原ASDEX数据的比较，对HL-2A装置上L-模约束品质和欧姆加热条件下斯必泽电阻率对温度的依赖关系进行了讨论。
