红海龟可以通过地球磁场强度来辨识纬度。新的研究发现，借助地球磁场方向，它们在辨识自己所在的经度上也很在行。
Loggerhead turtles sense latitude by the planet's magnetic field intensity, and new research finds they're good at determining their longitude too, probably via the field's inclination.
采用电波暗室作为船模预测的试验场地，进行天线方向图、天线耦合度(或隔离度)、近区场强等参数测试。
The antenna radiation pattern and antenna coupling or isolation as well as near electric field strength are measured by using anechoic chamber as the test site of ship model prediction.
对平行极化、方向指向阳极的样品，只要极化电场强度不是很大，宜选用正极性极化脉冲；
The positive polarity pulse will make better result for the samples than use negative polarity pulse.
