在封冻期长、冰盖层厚的地区,一种良好的打冰孔工具是提高冰期资料质量和工作效率的一个关键问题。去年,我们到六个站,对我省目前使用的几种打冰孔工具进行了调查,也作了一些试验。现将一些初步认识提出来和大家一起讨论。
In areas where the freezing period is long and the thickness of the ice sheet is thick, a good ice-drilling tool is a key issue to improve the quality and efficiency of glacial data. Last year, we went to six stations and conducted some surveys on several ice-hole drilling tools currently used in our province. We also made some experiments. Now some preliminary understanding put forward to discuss with everyone.
