Then, characteristic frequency of laid test coil is calculated, it is important to select the test frequency.
推导了放置式探头线圈的特征频率，为检测频率的选择提供了参考。
The sample was then exposed to a magnetic field applied parallel to the direction of flow of blood via a coil around the edge of the test tube.
然后，将样品放置在通过缠绕在试管边缘的线圈而产生的磁场中，该磁场的方向与血液流动方向相同。
Despite a worst-in-test 700 lumens (claimed) on a 14-watt draw, the EcoSmart didn’t seem particularly dim. And the globelike casing around the coil gave this CFL a nice, even glow.
虽然在测试中表现出700流明的最差亮度（耗电14瓦），其实并不是特别的暗。
