中山大学物理系为了开展低温物理和低温技术的研究工作,七九年起着手筹建低温物理实验室。到目前为止工作进展顺利,先后购置并安装了 YDS-4型及 KLN-20型液氮机各一套,及 HY-10型液氦机一套。继去年11月液氮机投产后,今年三月五日液氦机已试车成功,每小时生产液氦12.6升,其沸点为4.2K(-268.95℃)。以上
Sun Yat-sen University Department of Physics in order to carry out low-temperature physics and low temperature technology research work, starting in 1979 to set up a low-temperature physics laboratory. So far the work is progressing smoothly, one set of YDS-4 and one set of KLN-20 type liquid nitrogen machine and one set of HY-10 type liquid helium machine have been purchased and installed successively. Following the commissioning of the liquid nitrogen machine in November last year, the liquid helium machine has been successfully commissioned on March 5 this year. The hourly production of liquid helium is 12.6 liters and its boiling point is 4.2K (-268.95 ℃). the above
