| 摘 要： | 灵敏电流计特性实验中 ,相对误差达 30 %左右 ,经反复实验发现 ,误差原因出在接线柱外 ,经过改进 ,相对误差减小到 5 %之内 ,但在不加外电源时 ,电路中仍存在微小电流 ,其中的原因 ,仍需探讨。

| Abstract: | In the experiment of the sensitive galranometer,there were 30per cent of the relative errors.We found from repeated experiment the causes for the errors were from terminals.After improvement,the errors were decreased to less than 5per cent.But when the external powers were turned off ,there was still little electrics in the circuits.So the cause for it needs inquiring. |
