简介：研究了地震作用下非线性地基中桩基的3次超谐波共振问题．从地基桩中抽象出力学模型，考虑地基的非线性因素，运用Hamilton变分原理建立了桩基的非线性控制方程．利用Galerkin方法离散上述方程，基于多尺度摄动法研究了地震作用下非线性地基中桩的3次超谐波共振问题．以某嵌岩圆形桩为例，研究了地基土层厚度、剪切波速度及频率比对地震力的影响，数值模拟了非线性地基桩的3次超谐波共振响应，探讨了地震力、地基弹性及非弹性系数对超谐波幅频响应的影响，最后研究桩基产生3次超谐波共振时的时间历程曲线．结果表明，当地震波频率约等于桩基固有频率的1／3时，容易激发桩的3次超谐波共振响应；桩基的3次超谐波共振响应随着地震力、非弹性系数的增大而变得更加显著，随着弹性系数的增大而逐渐变小．

简介：采用放电等离子烧结(SPS)法将元素钛粉和镍粉制备成Ti-51%Ni形状记忆合金(SMAs)。研究目的是采用自由锻二次加工以提高SPS合金的性能。对自由锻前后合金的显微组织、相变温度和超弹性进行比较。结果表明，自由锻可以显著提高Ti-Ni形状记忆合金的拉伸强度和形状记忆性能，自由锻后合金的韧性从6.8%提高到了9.2%，超弹性的应变范围从5%增加到7.5%，应变恢复速率从72%提高到92%。Ti-51%Ni合金显微组织中含有立方奥氏体相(B2)基体、单斜马氏体相(B19′)、第二相(Ti3Ni4，Ti2Ni和TiNi3)和氧化物相(Ti4Ni2O，Ti3O5)。自由锻后再经500°C时效处理的最终样品的马氏体相变温度向高温方向偏移，这是由于Ti3Ni4相(透射电镜下可以观察到)的析出而导致基体中Ni含量的减少。总之，自由锻可以提高Ti-51%Ni形状记忆合金的超弹性和力学性能。

简介：摘要目的通过对甲状腺结节患者进行彩超联合组织弹性成像技术进行诊断，研究分析彩超联合组织弹性成像在甲状腺结节诊断中的应用价值，并面向大众进行推广。方法随机选取从2016年11月到2017年11月我院收录治疗的48例甲状腺结节患者作为研究对象，采用彩超联合超声弹性成像技术对患者病灶进行评价，研究其应用价值。结果甲状腺结节67个，穿刺活检证实45个良性，22个恶性；与穿刺活检结果比较中，彩超联合弹性成像诊断甲状腺恶性结节的符合率较高，为96.00%；彩超联合弹性成像诊断甲状腺结节的特异度、灵敏度以及准确度均较高，分别为91.11%、90.91%和91.04%。结论通过对彩超联合组织弹性成像的诊断结果进行分析得知彩超联合组织弹性成像在甲状腺结节诊断中的应用价值较高，值得推广应用。

简介：摘要目的探讨将彩超联合超声弹性成像应用于甲状腺结节良恶性临床诊断中的价值。方法临床纳入本院2016.10～2017.12期间收治的60例甲状腺结节（80个结节）患者作为研究对象，根据不同诊断方式分为研究组、对照组，均为30例。对照组单纯进行彩超检查，研究组进行彩超联合超声弹性成像检查，并将两组诊断准确率、误诊率、漏诊率进行对比。结果研究组诊断准确率为96.25%，明显高于对照组的83.75%；研究组无漏诊，共出现3例误诊，误诊率为3.75%，对照组漏诊率及误诊率分别为5.00%、11.25%，差异具有统计学意义（=8.681、P=0.003，=5.128、P=0.024，=4.054、P=0.044）。结论彩超联合超声弹性成像是一种理想的诊断方式，将其应用于甲状腺良恶性诊断中有利于进一步提升诊断准确性，减少漏诊、误诊，可为疾病定性、早期诊断、预后评估等方面提供可靠临床依据。
