已经证明人体普遍存在的隐性循经感传线具有低阻抗特性。动物体表是否也有类似的循经低阻线?这个问题对阐明经络的存在及其实质将有重要意义。实验在10只大白鼠和3只家兔相当于人体胃经的部位进行。皮肤电阻的测定用 CDMUsing two skin electrical impedance detectors

a low impedance line of 0.5mm in width

corresponding to the Stomach Channel of men was found on albino rats and rabbits.At most points of thisline

the skin impedance was found below 300 kilo-ohm

whereas that of the control points

i.e.2-3mm apart from the line

was above 500 kilo-ohm.The location of the line is relatively stable.Nosignificant difference was found among animals and among the determinations in various days foreach animal.Some experiments showed that this line is also an higher electrical potential line.Care-ful examinations showed that the skin of this line is paler and less abondant of hair than its adjacentareas.
