随着祖国大量培养高级技术人员的需要,许多规模很大的理工学院正在发展起来,在开始建立物理实验室的工作中,装设同时供给多数学生实验用的直流电源设备,是一件必要而困难的工作。今介绍一种价钱不贵、使用便利、而效能优良的直流电源,以供从事新建物理实验室的工作同志参考。 As the motherland has nurtured the need for a large number of senior technicians, many large-scale polytechnics are developing themselves. It is necessary and necessary to install a DC power supply for the experimental use of most students at the beginning of the establishment of a physical laboratory Hard work. This introduction of an inexpensive, easy to use, and excellent performance of the DC power supply, for the work of the new physics lab comrades reference.
