In this work, we report rapid hydrothermal growth of ZnO nanorods on a magnetron sputtered thick ZnO seed layer. The ZnO seed layer on the glass substrarte is monocrystalline and formed by 600 °C annealing for 1 hour after magnetic sputtering. The morphology of the ZnO grain in the ZnO seed layer plays a critical role in the growing of the ZnO nanorods, and the slant ZnO grain results in the slant ZnO nanorod and connected ZnO nonrods. It is found that the average growth of the ZnO nanorods is ~75 nm/minute. The rapid grow rate may be owing to the monocrystallie and the pure water solution of the growth solution.

Strengthening and energy saving is an important engineering of existing buildings. The test is preceded by using two groups of beams, during which the comparisons of cracking load，yield load and ultimate load are made between strengthened and un-strengthened beams. The test result shows that bending capacity of reinforced beams rose obviously. Finally, based on experimental study, the formula of ultimate bending capacity which can be used in engineering design is presented.

Background：Osteotomy and Orthopedics is the leading way to treat adult spinal deformity (ASD), but there are many surgical complications. meanwhile, oblique lumbar interbody fusion(OLIF) and anterior lumbar interbody fusion (ALIF) have becoming an increasingly popular surgical method of spinal surgery. Thus, the purpose of this study is to explore the feasibility and safety of minimally invasive anterior column realignment(ACR) in the treatment of adult spinal deformities. Methods:A total of 64 patients were included in the study. All patients received OLIF and/or ALIF and ACR, combined with Percutaneous pedicle screw fixation(PPSF). The surgical effect was evaluated by the operation time, bleeding volume, intervertebral space angle (IVA), lumbar lordosis (LL), the sagittal vertical axis (SVA), visual analog pain score (VAS), Japanese orthopedic association scores (JOA) and complications. Results: All patients completed 173 fusion segments; For 155 segments of ACR surgery, the average sagittal correction angle of each ACR segment was 15.3 ° ± 5.8 °. The mean preoperative and postoperative lumbar lordosis were, respectively, -16.7 ° ± 6.4 °and -48.6 ° ± 10.7 ° (p<0.001). JOA, VAS and other scores were significantly improved compared with those before operation. Conclusion: Anterior column realignment via a minimally invasive hybrid approach for adult spinal deformity can achieve good clinical outcome and deformity correction.

In this paper, with the help of program Thufiber, fiber model is used to simulate bridge piers, solid element is used to simulate the superstructure in program MSC.Marc. The effects of the travelling wave on the nonlinear seismic response of the long-span continuous rigid-frame bridge with high piers are analyzed under 2008 Wenchuan Earthquake Wave excitation. The results show that travelling wave has much effect on displacement and shear force of high piers of the bridge. The displacement of the pier top decreases 20% to 50% and the shear force at the pier base increases from 20% to 30%.
