This manual describes how to build a 'permanent magnet generator' (PMG).
本手册介绍了如何建立一个永久磁铁发电机。
Moreover, we investigated the influence of the magnetic inhomogeneity of the PMG on levitation force of the bulk superconductor in a quasi-static state.
此外，在准静态测试条件下，实验研究了导轨表面磁场不均匀性对高温超导块材的悬浮力性能的影响情况。
In this article, a permanent magnet guideway-high temperature superconductor (PMG-HTS) interaction magnetic levitation (Maglev) system was designed and investigated.
设计和研究了一种永磁导轨与高温超导体作用形成的磁悬浮系统。
The influence of the time-vary external magnetic field perturbation on the guidance force of HTS bulk over the PMG was investigated by experimental methods in this dissertation.
本文通过实验的方法研究了时变外磁场对稳定悬浮于永磁导轨上方的高温超导体块材的导向力性能的衰减影响。
Result:the number of neural stem cells in dentate gyrus of the mice in HMG was higher than that in PMG(P<0.01), but there was no difference between the PMG and the control(P>0.05).
结果：记忆力强组小鼠海马齿状回的神经干细胞数目明显多于记忆力弱组（P<0·01），而记忆力弱组与对照组比较，其神经干细胞数目差异无统计学意义（P>0·05）。
Collectors throughout the world are familiar with NGC and PMG grading standards, and this makes it possible for them to buy COINS even if they do not have the opportunity to view the items personally.
世界各地的收藏家都了解NGC和PMG的评级标准，这使得他们在买卖钱币时甚至不需要亲自察看钱币。
