| Abstract: |
| Objective To analyze the accelerated life test (ALT) of sensors so as to lay foundation for further tests. Methods The ALT was conducted and the data was analyzed by methods of inverse moment and best linear unbiased estimation (BLUE). Results Each parameter for the test was determined, which provided evidence for data processing. Conclusion Using inverse moment and BLUE to estimate each parameter was effective, and could analyze each index of sample reliability. |
