Table 2

The coupling coordination degree standard.

Level	Degree
0.8 < D ≤ 1	Superior coordination (V1)
0.7 < D ≤ 0.8	Moderate coordination (V2)
0.6 < D ≤ 0.7	Slight coordination (V3)
0.5 < D ≤ 0.6	Slightly incoordination (V4)
0.4 < D ≤ 0.5	Moderately incoordination (V5)
0 < D ≤ 0.4	Extremely incoordination (V6)
