The results show that the bonding temperature is below 250℃, the helium hermetic capability of both silicon-BCB-silicon and silicon-BCB-glass package are better than 6×10~ -4 Pa·cm^3/s. The shear strength is enough for package. The hermeticity is still good after the 15 cycles’ thermal shock test. The relationship between the leakage rate and the distance from the hole to the device border were also discussed with a seepage model.展开更多

Methods: A total of 170 cases who met the inclusion criteria were randomized into two groups, 85 in each group. Patients in the observation group practiced simplified taijiquan besides receiving auricular point sticking, while patients in the control group only received auricular point sticking. The therapeutic efficacies were evaluated after 8 weeks. Results: The total effective rate in the observation group was 96.5%, versus 67.1% in the control group, showing a statistically significant difference(P<0.01). Conclusion: Combined simplified taijiquan and auricular point sticking works accurately for perimenopausal insomnia, and the total effective rate is better than that of auricular point sticking alone.展开更多
