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 P < 0.05, Chi2 = 189.544 in first round and 235.232 in second round. The average degree of expert's authority was 85%.
