双语例句
- Equipotential connection may not connect with the manual or natural earthing to become earth-free equipotential connection.
等电位联结也可不与人工或自然接地体连接的，成为不接地的等电位联结。 - Magnetic behaviors of Fe-Nd-P and Fe-Ce-P alloy films are studied. Magnetic measurements show that the saturate intensity of magnetization, remanence and coercive force of these alloy films are higher than those of the rare earth-free Fe-P alloy films.
研究了Fe-Nd-P和Fe-Ce-P合金镀层的磁性能，经测量发现Fe-Nd-P、Fe-Ce-P合金镀态样品与没有加稀土的Fe-P合金镀态样品相比，饱和磁化强度、剩余磁化强度和矫顽力都要高。
