Following the theory of Дер-шьарц

the authors designed and constructed a star-type resistor network.It was found that

the formulae of Дер-шьарц are not valid for the paraxial region.After repeated experiments the authors obtained an improved design.As shown by measurement result

the modified network is superior to the conventional crosstype network

with regard to both statistical error and systematic error

particularly for the simulation of curved boundary conditions.When the boundary doesn’t exactly pass through lattice points

the authors suggest nonlinear interpolation method to improve accuracy. The paper reports this developmental work

together with measurement result and error analysis

the latter two agreeing well with each other.It seems clear that star-type resistor network is of practical value.
