In the current mark process, the method of professor's proportion to define the proportion of index of evaluation is generally employed. but in the use of the method, owing to the difference of the different professors' experiment or the angle which they view the problem, they will come to different conclusions at one index of evaluation, they even make subjective judgment, and then fail to define the proportion of the index of evaluation. On the basis of the defines of Entropy by Shannon, this text define the Entropy of the index of evaluation by the judge-array which is made of the index value of all cases, and uses the Entropy of the index value to define the Entropy proportion. It then lines up the case by closing degree of all cases and the ideal dot. Finally, we can pick up the best case. This method solves the problem of the index of evaluation, presenting subjective judgment in the mark process, and makes the mark process fairer and more scientific.
