船冰作用力的预报是冰区船航行性能评估环节的重点。本文针对某冰区航行船开展操纵性斜航模型试验研究,采用以聚丙烯为主材的圆形非冻结模型冰,通过模型试验给出船在无冰水域和中高密集度浮冰区的船体受力,研究船体在不同航速和漂角下的船体受力特性,并基于典型工况分析试验数据的重复性,发展冰区航行船的非冻结模型冰模型试验技术。研究结果表明:浮冰密集度、航速和漂角的增大会使船体受力增大,高密集度和大漂角下船冰接触区域更大,试验数据重复性也较好。

为明确铝热剂反应的着火特性,利用最低着火温度(minimum ignition temperature,MIT)和最小点火能(minimum ignition energy,MIE)测试装置,结合TG-DSC方法对4种Al粉与Fe_(2)O_(3)质量比为1∶4,1∶3,1∶2,1∶1的层状和云状Al/Fe_(2)O_(3)铝热剂进行了着火敏感性研究.结果表明,4种配比试样的粉尘层、粉尘云MIT均超出相关标准常规测试范围,在空气中质量比为1∶3铝热剂的反应触发温度为888℃,活化能为248.49 kJ/mol,说明铝热反应不容易触发;相同质量比的Al/Fe_(2)O_(3)粉尘云的MIE远高于粉尘层,层状MIE最低值为0.7 J,着火敏感性较强,这是因为Fe_(2)O_(3)在粉尘云状态的反应中充当惰化剂,而在粉尘层状态反应中为反应提供了活性氧自由基.

广西某工程项目地质条件复杂,土层力学特性变化明显,土层刚度呈现“上硬下软”状态,且分布厚度不一,多栋建筑封顶后出现不均匀沉降,本文旨在确定一种基础加固方案能够较好地解决以上问题。针对土层“上硬下软”的特点,对于沉降较大的区域创新采用“Φ377+Φ127组合钢管桩”进行基础加固,防止沉降继续发展。浅层硬壳层采用Φ377钢管桩提供承载力,深部软土层采用Φ127钢管桩深入原CFG桩下1~2 m,结合注浆工艺,加固松软土体,对原CFG桩桩底进行加固。对于沉降较小的区域创新采用高压注浆深层扰动技术,增加局部沉降。采用动阻力控制作为终桩条件,解决土层起伏剧烈地区桩端持力层无法判断的工程难题。“Φ377+Φ127组合钢管桩”极大地提高了原工程桩承载力,从而解决了坚硬土层难以沉桩、软弱土层承载力不足的工程难题。该基础加固方案成功解决了既有建筑的不均匀沉降工程难题,积累了宝贵的工程经验,为“上硬下软”复杂土层既有建筑基础加固提供了新思路,具有显著的经济效益和社会效益。

忆阻器可以用来模拟生物神经突触和描述电磁感应效应.为了探索电磁感应作用下异构神经网络的动力学行为,本文首先使用双局部有源忆阻器耦合一个Hindmarsh-Rose (HR)和两个FitzHugh-Nagumo (FN)神经元,构成忆阻电磁感应下分数阶异构神经网络.然后利用相图、分岔图、李雅普诺夫指数谱和吸引盆等动力学分析方法,对该网络进行数值研究.结果表明该神经网络表现出丰富的动力学行为,包括共存行为、反单调现象、瞬态混沌和放电行为等,为研究人脑放电行为提供支持,随后进一步利用时间反馈控制方法实现了双稳态的控制.最后,在嵌入式硬件平台上实现了该神经网络,验证了仿真结果的有效性.
