In this paper, eight kinds of coal and fifteen additives with different structural characteristics were selected to evaluate the correlation between structural characteristics of additives and properties of coal water slurry.

This paper mainly applied the general matching law in the research of Salisbury screen s reflection nature.

The model of query by humming music retrieval contains three parts: the features extraction of humming music, melody representation and melody matching.

In this paper, we begin with briefly introducing some classic algorithms about audio processing, and apply AMDF algorithm into pitch extraction to get the pitch feature and rhythm feature, then introduce melody matching algorithm in details.

Algorithm of matching law based on optimal policy search model

An algorithm leading to matching law is then derived from the optimal algorithm.

By the theoretical analysis and proof,a set of matching rules are summarized for depicting inherent relations among matching results of entities.

A matching rule was set up for the real gear tooth surface best-fitting the theoretical one, and four different algorithms were developed to calculate the deviations between the two surfaces.
