Since the suspended sediments have severe influence on acoustic radiated field of transducer, it is significant for sonar system to analyze the influence of suspended sediments on acoustic pressure in the seafloor mining environment. Based on the KZK （Khokhlov-Zabolotkaya-Kuznetsov） equation, the method of sound field analysis in turbid water is proposed. Firstly, based on the analysis of absorption in clean water and viscous absorption of suspended sediments, the sound attenuation coefficient as a function of frequency in the mining environment is calculated. Then, based on the solution of KZK equation in frequency domain, the axial sound pressure of transducer in clear water as well as turbid water is simulated using MATLAB. Simulation results show that the influence of the suspended sediments on the pressure of near field is negligible. With the increase of distance, the axial sound pressures of transducer decay rapidly. Suspended sediments seriously affect the pressure in far-field. To verify the validity of this numerical method, experiment is designed and the axial sound pressure of transducer with a frequency of 200 kHz and a beam width of 7.5~ is measured in simulated mining experiment. The results show that the simulation results agree well with the experiments, and the KZK equation can be used to calculate the sound field in turbid water.

为了研究长盾构隧道在考虑行波效应的地震动作用下的纵向响应规律,以上海沿江通道盾构隧道为原型,利用多功能振动台台阵系统,设计并完成了盾构隧道的多点振动台模型试验。鉴于长大盾构隧道工程规模和多点振动台试验系统的能力,试验几何相似比确定为1∶60;基于Buckingham-π定理以及量纲分析方法,确定了试验所需的土与结构的动力相似关系;为了模拟沿隧道纵向的行波输入,设计并制作了节段式模型箱,箱体总长22m,分为4个主动箱以及3个从动箱,箱体之间通过弹簧铰相连;以砂子和锯末按照一定质量比拌合来优化配置模型土,并通过室内三轴试验进行测试验证;考虑土-结构相对刚度相似比为控制指标,选取PE材料作为模型材料;根据刚度等效原理,设计并制作了盾构隧道的多尺度结构模型。试验以上海人工波为地震动输入,通过一系列工况的多点振动台试验模拟,得到了行波效应下盾构隧道模型结构的地震响应规律。试验测试数据包括行波效应下模型土和模型结构的加速度响应、隧道管环环缝的伸缩量响应等。对比分析了一致输入和行波输入下隧道结构的动力响应。试验结果表明:相比一致激励输入,行波效应会明显放大模型结构的加速度响应和环缝变形响应,从而对隧道抗震产生不利影响;地震动非一致激励应该在盾构隧道的纵向抗震设计中得到足够重视。

AIM To investigate the association between interferoninduced protein with tetratricopeptide repeats 1(IFIT1) polymorphisms and interferon-α(IFNα) treatment efficiency among Chinese hepatitis B virus(HBV) infection *** Two hundred and twenty five newly diagnosed chronichepatitis B(CHB) patients were enrolled in the study. All of these patients received IFNα treatment for a course of 48 wk, and were followed up for 24 wk after the treatment was end. Clinical information about virological response, hepatitis B e antigen(HBe Ag) seroconversion rate and combined response at the end of the treatment, as well as the sustained response by the time of following up 24 wk after the treatment, was collected. Four tag-single nucleotide polymorphisms(SNPs) of IFIT1 were selected and assessed for their association with these clinical *** At the end of the treatment, HBe Ag seroconversion was observed in 27.1% patients. Thirty-six point nine percent patients achieved virological response, and 15.6% patients exhibited combined response. Sustained response was obtained in 26.2% patients. The main HBV genotype of the study was genotype B. Patients who infected with HBV genotype B or C showed better treatment efficiency, no matter which clinical outcome was considered. Among the four SNPs assessed, rs303218(A > G) was found to be significantly associated with the end point virological response when assuming additive model [OR = 0.64(95%CI: 0.42-0.96), P = 0.032]. Patients who carried rs303218 GG genotype had a rather higher rate of achieving virological response(response rate: 52%, OR = 0.40, 95%CI: 0.18-0.91; P = 0.028) when compared to those had AA genotype(response rate: 27%). The most significant interaction was observed in patients who had relative lower baseline aspartate transaminase. No association between SNPs and HBe Ag seroconversion, combined response or sustained response was *** IFIT1 involves in the regulation of IFNα treatment f
