| 1 | Seismic wave input method for three-dimensional soil-structure dynamic interaction analysis based on the substructure of artificial boundaries显示文摘The method of inputting the seismic wave determines the accuracy of the simulation of soil-structure dynamic interaction. The wave method is a commonly used approach for seismic wave input, which converts the incident wave into equivalent loads on the cutoff boundaries. The wave method has high precision, but the implementation is complicated, especially for three-dimensional models. By deducing another form of equivalent input seismic loads in the fi nite element model, a new seismic wave input method is proposed. In the new method, by imposing the displacements of the free wave fi eld on the nodes of the substructure composed of elements that contain artifi cial boundaries, the equivalent input seismic loads are obtained through dynamic analysis of the substructure. Subsequently, the equivalent input seismic loads are imposed on the artifi cial boundary nodes to complete the seismic wave input and perform seismic analysis of the soil-structure dynamic interaction model. Compared with the wave method, the new method is simplifi ed by avoiding the complex processes of calculating the equivalent input seismic loads. The validity of the new method is verifi ed by the dynamic analysis numerical examples of the homogeneous and layered half space under vertical and oblique incident seismic waves. | Liu Jingbo Tan Hui Bao Xin Wang Dongyang Li Shutao | 2019 | Earthquake Engineering and Engineering Vibration2019，18，4： | 11 |
| 2 | Artifi cial liver support system in treatment of liverfailure after acute poisoning显示文摘BACKGROUND: Acute poisoning (AP) may cause failure of the liver and kidney, and evendeath. This study aimed to investigate the efficacy of artificial liver support system (ALSS) on thetreatment of liver failure after acute poisoning.METHODS: A total of 31 patients with liver failure caused by AP were admitted to emergency ICU,central ICU, and Department of Gastroenterology from 2005 to 2009 in Zhongshan Hospital Affi liatedto Xiamen University, China. Among them, 13 patients served as a treatment group, and used ALSS inaddition to detoxifi cation treatment and protective treatment of liver function, and the other 18 patientsserved as a control group receiving detoxifi cation treatment and protective treatment of liver function.RESULTS: In the treatment group, 10 patients (76.9%) were cured or improved, 2 died, and1 was discharged against advice. In the 18 patients in the control group, 7 (38.9%) were cured orimproved, 3 died, and 8 were discharged against advice. There was a significant difference in therates of improvement between the two groups (P〈0.05).CONCLUSION: ALSS is a safe and effective clinical method for the treatment of acute toxicliver failure. | Li-gang Chen Bayasi Guleng Jian-lin Ren Jian-min Chen Lin Wang | 2011 | World Journal of Emergency Medicine2011，2，4： | 2 |
