Numerous vibration-based techniques are rarely used in diesel engines fault diagnosis in a direct way, due to the surface vibration signals of diesel engines with the complex non-stationary and nonlinear time-varying fea- tures. To investigate the fault diagnosis of diesel engines, fractal correlation dimension, wavelet energy and entropy as features reflecting the diesel engine fault fractal and energy characteristics are extracted from the decomposed signals through analyzing vibration acceleration signals derived from the cylinder head in seven different states of valve train. An intelligent fault detector FastICA-SVM is applied for diesel engine fault diagnosis and classification. The results demonstrate that FastlCA-SVM achieves higher classification accuracy and makes better general- ization performance in small samples recognition. Besides, the fractal correlation dimension and wavelet energy and entropy as the special features of diesel engine vibration signal are considered as input vectors of classifier FastlCA- SVM and could produce the excellent classification results. The proposed methodology improves the accuracy of fea- ture extraction and the fault diagnosis of diesel engines.

本文采用2013年和2018年中国家庭收入调查(CHIP)数据,分析我国老年人的收入结构特征,并进一步探究不同类型养老保险对老年人收入的影响。研究结果发现:(1)我国老年人总可支配收入水平显著提高,其中与2013年相比,2018年我国老年人来自个体工资性收入、家庭转移性收入和社会保障性收入的水平均呈现增长趋势,其涨幅分别为288.6%、172.5%和50.9%;(2)收入结构发生显著变化,相比2013年,2018年老年人工资性收入占总收入比重大幅增加,来自家庭转移性收入的比重略微增加且相对稳定,来自社会保障性收入的比重大幅下降但其仍是老年人收入的第一大来源;(3)与未参保老年人相比,参加养老保险的老年人收入水平较高,尤其是参加企事业单位养老保险与商业等其他养老保险的老年人,但与2013年相比,2018年养老保险的正向作用有所减弱,保障水平较高的企事业单位养老保险和商业等其他养老保险对城镇老年人与老年女性收入的正向作用较大。据此,需完善养老保险体系,逐步缩小各类型养老保险待遇差距,充分发挥其养老保障功能。

[目的]通过分析种植方式对两种菌根类型树种吸收根性状的影响,揭示物种共存的适应条件。[方法]本研究选择8个树种(5个AM树种和3个EM树种)的单种和所有树种混种的样地,分析不同种植方式(单种vs混种)下两类型菌根(AM vs EM)树种吸收根(1~2级根)的主要形态性状(根直径、比根长、根组织密度、单根长)和构型性状(根分支强度、根分支比)及菌根侵染率的差异。[结果]菌根类型极显著影响吸收根的形态和构型性状(p0.05)。AM树种根性状间的相关程度高于EM树种,混种大幅度降低AM树种根性状间的相关性。混种降低AM树种根形态性状的可塑性(比根长除外),增大其构型性状的可塑性;混种降低EM树种根组织密度的可塑性,增大根直径、构型性状及侵染率的可塑性。[结论]AM和EM树种的根形态和构型性状均有显著差异。混种对AM和EM树种根性状的可塑性有不同程度的影响,主要增大AM树种的分支强度,降低EM树种的根组织密度。可见,不同菌根树种可以通过调节不同根性状变化来实现物种共存。

为揭示考虑二次受力UHPC加固桥墩偏压受力的损伤机理和极限状态,设计制作了UHPC加固RC墩和未加固墩构件,并进行了相应的试验研究和理论分析,并与未加固墩进行了比较。开展了考虑二次受力的UHPC增大截面法加固RC桥墩的小偏压试验,研究了不同初始受力条件下加固墩的破坏模式和极限承载力。结合有限元模型讨论了UHPC抗压强度、加固层的厚度和配筋率对极限承载力的影响。根据极限状态下的受力特性和平衡关系,推导了UHPC加固RC墩偏压极限承载力计算公式。结果表明:UHPC搭配钢筋网加固墩小偏压承载力与未加固墩相比,提升幅度达到了183%以上。UHPC强度对试件极限承载力的影响较大,UHPC厚度增大对加固试件承载力提高也较明显,加固层配筋率对构件承载力的提高影响较小。初始荷载的增大会降低原墩的混凝土利用率,降低加固墩的极限承载力。所提出考虑二次受力公式的计算承载力与实测值误差在3%之内,与有限元计算值误差在8%之内,具有较高的计算精度。研究结果可以为UHPC加固RC墩偏压承载力计算提供理论依据。
