| 8. | Second , when cfrc specimen is compressed , its capacity will change with the change of pressure , mostly because the relative dielectric constant changes with the change of pressure , so the compression sensibility of cfrc can also be reflected by capacity measurement , and the change of capacity with stress - strain is sensitive , and the data of measurement are stable
Cfrc在受压时其电容会随压力的变化而变化，主要是因为cfrc的相对介电常数随压力的变化而变化，所以通过电容的测量同样可以反映cfrc的压敏性，而且电容随应力、应变的变化灵敏，测试数据稳定。 |
