英文摘要：

In this paper we consider the optimal design of lack of fit test for a linear model defined on a discrete region of finite points. We propose a optimality criterion in terms of the average minimal bias. An algorithm for constructing the local exact optimal design is proposed. An example shows that the optimal design obtained by the algorithm is of a certain uniformity on the design region.
