Methods With Delphi method adopted,two rounds of questionnaire survey were carried out in 20 experts,the feedback data were statistically analyzed in terms of concentricity,coordination and authority using SPSS software. Results The recovery rates of the two round survey were all 100%; the coordinate coefficient was 0.658 in the first round and 0.622 in the second. And results passed the Chi-square test with P0.05,χ2=189.544 in first round and 235.232 in second round. The average degree of expert＇s authority was 85%. Conclusions The enthusiasm and speciality of the 20 experts were high,and their opinions are of high reliability with great coordination.
