Abstract:The error spread law is based on the obvious function.However,in practice,many variables can not be expressed by the obvious function from other variables,only can be expressed by the latent function.Here,the common form of error spread law based on latent function is presented and applied to the line engineering.It is shown that this method is feasible and resultful.
Keywords:latent function  error spread law  accuracy  line engineering  transition curve
