查询词典 relatively countably compact subset

The model of the outer layer hard and inter layer soft magnetic structure was suggested that the amorphous ribbon and wire are constituted by the relatively"hard" magnetic"shell"with relatively high magnetic coercivity and relatively"soft"magnetic "core"with relatively low magnetic coercivity.

非晶材料的尖锐脉冲电压现象是由于具有显著的不可逆壁移磁化过程导致大巴克豪森跳跃所造成的，脉冲的尖锐性与动态磁滞回线的形态密切相关，回线的方形度越高，则脉冲愈尖锐。

When preset heating rate is 500℃/s and the non-pretreated NdFeB alloy compact is sintered at 600℃, relatively densified compact can obtain.

未经预处理的NdFeB合金生坯当预设升温速度为500℃／s时，在600℃的低温即可使压坯基本烧结致密化，磁体中白色富Nd相的分布既很均匀也很弥散。

It is found that comparing with compact single circuit transmission mode, T-type compact transmission mode of two circuits on the same tower and conventional transmission mode of two circuits on the same tower, the transmission mode of two circuits with same phase sequence in the same tower window need narrower corridror width, and the radio interference and audible noise caused by this transmisison mode is relatively lower, especially, the corona loss is reduced evidently, thus better economic and social effects can be obtianed by applying this transmission mode in a short distance under a centain condition.

从走廊宽度、电磁环境、潜供电流和防雷特性4个方面对750 kV同塔同窗同相序紧凑型输电方式进行了分析，发现与单回紧凑型、同塔双回T型紧凑型及同塔双回常规型输电方式相比，采用同塔同窗同相序紧凑型输电方式所需的走廊较小，无线电干扰和可听噪声相对较低，尤其是电晕损失明显减小，采用这种方式在一定条件下可获得较好的经济效益与社会效益。

Through the analysis of the second power Cartesian product of natural number set N——N×N and the thirdpower Cartesian product of natural number set N——N×N×N,obtains the conclusion that they all have the bijective relation to natural number set N,it means that the set N×N and the set N×N×N are all countably infinite.

通过对自然数集合N的二次笛卡尔积运算———N×N和三次笛卡尔积运算———N×N×N的详细分析，得出了它们与自然数集合N之间都存在双射关系结论，即集合N×N和集合N×N×N都是可数无穷的。
