The method of the site dynamic characteristic tests of the composite foundations is discussed. The test results show that fireworks bomb may replace demolitions as the vibration resource. Vibration time is about 0.1 sec. Horizontal vibration major frequency is at 22.476 - 56.436 Hz, and vertical vibration major frequency is at 15.538 - 55.884 Hz. The pile arrangements of the composite foundation in the same site have more effect on the acceleration peak value. From the point of vibration, the anti-seismic effect of the CS piles with CFG core is better than others.展开更多

The reliability of these grafts has been proved with an established clinical use and morbidity to the donor site is minimal if harvesting and donor site selection if appropriate. Use of double or multiple grafts to reconstruct a complex defect of the nose has not been described and our report is meaningful for the fact that it describes a further use of the surgical concept of grafting.展开更多
