4 test principle

The resistivity is calculated from the resistance of the sample, the length of the sample and the cross-sectional area. Resistance and sample length obtained by the direct test. for SiC single fiber, the cross-sectional area calculated from the measured diameter of the sample obtained; for SiC fiber bundle, the cross-sectional area of the sample according to the close Degree and linear density calculated. Resistance and cross-sectional area of the product, and then the ratio of the length of the sample is the resistivity of the sample. Test principle shows Intention see Figure 1. ......
