BACKGROUND Prophylactic loop ileostomy is an effective way to reduce the clinical severity of anastomotic leakage following radical resection of rectal *** surgical site infection(SSI)is a common complication after ileostomy *** To evaluate the efficacy and safety of the micro-power negative pressure wound technique(MPNPWT)in preventing incisional *** This was a prospective,randomized controlled clinical trial conducted at a single center.A total of 101 consecutive patients who underwent ileostomy closure after rectal cancer surgery with a prophylactic ileostomy were enrolled from January 2019 to December *** were randomly allocated into an MPNPWT group and a control *** MPNPWT group underwent intermittent suturing of the surgical incision with 2-0 Prolene and was covered with a micro-power negative pressure *** surgical outcomes were compared between the MPNPWT(n=50)and control(n=51)*** factors for incisional SSI were identified using logistic *** There were no differences in baseline characteristics between the MPNPWT(n=50)and control groups(n=51).The incisional SSI rate was significantly higher in the control group than in the MPNPWT group(15.7%vs 2.0%,P=0.031).However,MPNPWT did not affect other surgical outcomes,including intra-abdominal complications,operative time,and blood *** hospital stay length and hospitalization costs did not differ significantly between the two groups(P=0.069 and 0.843,respectively).None of the patients experienced adverse effects of MPNPWT,including skin allergy,dermatitis,and *** also helped heal the infected *** study indicated that MPNPWT was an independent protective factor[odds ratio(OR)=0.005,P=0.025)]and diabetes was a risk factor(OR=26.575,P=0.029)for incisional *** MPNPWT is an effective and safe way to prevent incisional SSI after loop ileostomy closure.

基于CHI-LMD方法的转子振动信号分析

振动与冲击 2014年第15期33卷 58-64页

作者：邓林峰赵荣珍兰州理工大学机电工程学院兰州730050 兰州理工大学数字制造技术与应用省部共建教育部重点实验室兰州730050

为解决三次样条插值(Cubic Spline Interpolation)局部均值分解(Local Mean Decomposition)(CSI-LMD)方法的分解精度及计算效率偏低问题,提出了一种利用三次Hermite插值(Cubic Hermite Interpolation,CHI)和正交性准则(Orthogonality Criterion,OC)对CSI-LMD进行改进的新方法。该方法首先以三次Hermite插值代替三次样条插值,求解信号的上/下包络线及均值曲线;其次,用OC判据作为分解过程中乘积函数(Product function,PF)迭代结束的判断条件;最后,与LMD方法的其他步骤相结合,形成了一种新的CHI-LMD方法。仿真和实验结果表明,CHI-LMD方法在分解精度、时间消耗、PF分量的正交性以及分离故障转子的特征振动成分等方面,比CSI-LMD方法更具优势。

针对风电轴承故障源域数据和目标域数据特征分布不同而导致的故障诊断精度偏低问题,提出一种利用改进残差神经网络进行风电轴承故障迁移诊断的方法。该方法将卷积核和池化核设定为与一维振动信号卷积运算相适应的尺寸,从振动信号直接提取轴承的故障特征;在一维残差网络中同时使用批量归一化和实例归一化,进一步增强模型的特征提取能力;在模型训练阶段,通过源域数据和目标域数据的多核最大均值差异构建新的损失函数,以提高模型在不同分布数据集上的迁移学习及分类能力。利用故障轴承实验数据对方法的有效性进行验证,结果显示,即使受到轴承变转速运行工况和故障振动信号含噪声干扰成分的双重影响,该方法仍然可提取出轴承故障的重要特征,并实现不同工况轴承故障的迁移诊断和准确分类,这对于发展复杂环境下的旋转机械智能故障诊断技术具有参考价值。
