查询词典 northwest by north

The earth has a magnetic north pole and a magnetic south pole. These poles are close to, but not exactly at, the earth's axis of rotation . What's more, they are constantly moving!

地球也有南、北两磁极，这两极很接近地球自转的轴线，但并不完全相同；再者，它们不断地在改变位置！

When the solar particles reach our planet, the electromagnetically-loaded particles will move in a spiral along the magnetic lines: from the magnetic north pole to the magnetic south pole and back.

In 1992, a three phase double circuit line between Goudey and Oakdale station was reconstructed to six-phase line and was operated commercially by New York state electric and gas. It is a milestone from theoretical research to practical application in the development of six-phase transmission.With the decrease of cultivated land and the environmental problem in china, it is an important factor to improve power transmission density in the construction of electric network, and the predominance of six-phase transmission is obvious in this aspect.

六相输电是多相输电的一种，在国外六相输电技术作为提高输电线路功率传输密度，节约线路走廊空间的重要手段得到了充分的重视，对六相输电技术的研究也取得了很大的进展。1992年，美国纽约电力和天然气公司将Goudey到Oakdale之间的一条双回线路改造成了六相输电线，并且已经投入了商业运行，这标志着多相输电技术已经从理论研究向实际应用迈出了重要的一步。
