摘要：

It is proved with a typical electrical circuit used in most torsion balance experiments that electrical feedback will not introduce an extra fluctuation force for the Brownian motion of a torsion balance; a reduced thermal noise level may be achieved by partial cooling of certain components of the electrical circuit without cooling the whole set of the balance at the equivalent temperature.
