earth connection接地将被检者和电生理仪及周边仪器用电阻很小的铜线接入大地之谓。由于接地不良不仅会使仪器不能正常工作,还可能会给受检者带来危险,因而必须确保接地,而且为避免涡流干扰,必须在同一点接地。earthing electrode接地电极安在人体上并将其接地的电极,在肌电图 Earth connection grounding will be seized and electrophysiological instruments and peripherals with a very small resistance of the copper access to the earth that. Because of poor grounding, not only can the instrument not work properly, it may also be dangerous to the subject, so it must be grounded. To avoid eddy current interference, it must be grounded at the same point. earthing electrode Grounding electrode An electrode placed on the human body and grounded to it, in the EMG
