Range analysis of freeze-thaw splitting test.

Indicator		Carbon fiber	Graphite
Splitting intensity ratio	K1	244.2	250.1
	K2	247	246.6
	K3	249.9	244.4
	k1	81.4	83.37
	k2	82.33	82.2
	k3	83.3	81.47
	Range	1.9	1.9
	Optimization scheme	0.5	20

K represents the total value of each factor at each level, and k represents the average value of the total value, indicating the influence of this factor on the test parameters.
