Measurement Method of Spatial Autocorrelation Index Based on Nominal Scale;

In this paper,the research is based on nominal scale gird data.

In this paper,the estimation of parameters for nominal scale population is discussed at first,Then the way of liklihood ratio test is given to judge the problem about the equal of two nominal scale pooulations,besed on the limit distribution of likelihood ratio statistic.

The paper discuss empirical Bayes estimation and linear empirical Bayes estimation of the parameters of one nominal scale population.

The article introduces the characteristic and algorithm of CAPDP Systematically, including the express of process dimension, the determination of name dimension and deriation the determination of name margin and its Variation, the adjustment of deviation and margin.

The research progeny about corrosion character and deterioration mechanism of mechanical property of the corroded steel bars in concrete are mainly summarized and discussed in this article,which also expounds the deteriorating regularity of nominal strength and ductility of the corroded steel bars .

The necessity of marking minimum thickness and nominal thickness is analyzed.

thickness of the formed head shall not be less than the value derived from that head nominal thickness deduct plate thickness minus deviation C1.
