alternating electromagnetic field meaning in Chinese
交变电磁场
Examples
- Study on the dynamic characteristics of natural alternating electromagnetic field
天然交变电场动态特征研究 - It uses the encouragement of step wave or other impulse current field source to produce the transition process field in earth . in the moment of shutting the power it produce the volute alternating electromagnetic field . from the abnormity of measuring the attenuation character of the second induction electromagnetic field , which produced by underground medium with time change , the conductive capacity and the position of the underground non - homogeneous substance can be analyzed
瞬变电磁法( transientelectromagneticmethod )是一种时间域的电磁勘探方法，利用阶跃波或其它脉冲电流场源激励，在大地产生过渡过程场，断电瞬间在大地中形成涡旋交变电磁场，测量这种由地下介质产生的二次感应电磁场随时间变化的衰减特性，从测量得到的异常分析出地下不均匀体的导电性能和位置，从而达到解决地质问题的目的。 - Experiments on the measurement of temperature with thermocouple in alternating electromagnetic field are conducted . the effects of factors on the measurement result are studied , such as position , integral time , environment temperature , power supply , heating power and encapsulation mode of thermocouple . effective measures are obtained to decrease the negative effect of alternating magnetic field , which ensure that accurate measurement will be acquired in the following experiments
