提出带隙特性丰富的蜂窝截面、正交截面和X截面三种周期性隔振桩,采用平面波展开法对三种隔振桩进行频散及带隙分布展开研究,揭示平面内和平面外首阶完全带隙的起始频率、截止频率以及带宽随构型影响因素如周期常数、填充率以及控制尺寸变化的规律,为该类型排桩应用及设计选型提供理论依据。研究表明:降低周期常数可以增加三种隔振桩平面内和平面外的首阶带隙带宽,但是也会提高它们首阶带隙的起、止频率;增大填充率可以增加蜂窝截面隔振桩平面内和平面外首阶带隙的带宽,也会提高首阶带隙的起、止频率;正交截面隔振桩和X截面隔振桩首阶带隙伴随填充率变化规律不明显,二者的几何控制尺寸更复杂、带隙调节能力更丰富。

采用溶胶-凝胶法制备了SiO2-WO3催化剂,并采用XRD、FT-IR、BET、TG-DTA等方法对催化剂进行表征。以苯并噻吩(BT)为模型化合物,H2O2为氧化剂,考察了催化剂的活性元素、制备方法、n(W)/n(Si)和焙烧温度对其催化氧化脱硫活性的影响。结果表明,W的引入降低了SiO2的比表面积,SiO2-WO3催化剂中W的主物相为WO3。在以W为活性组元,且n(W)/n(Si)为0.1时,500℃焙烧得到的SiO2-0.1WO3催化剂具有最好的催化脱硫活性。在模拟油20mL、催化剂SiO2-0.1WO3用量0.04g、n(H2O2)/n(S)为15.9、乙腈/模拟油体积比0.3、65℃反应60min的条件下,苯并噻吩模拟油脱硫率可达99.3%。

为了比较浮置板轨道预制短板型式与现浇长板型式动力特性及服役性能的差异，将轨道结构作为一种周期性的无限结构，根据两种轨道自身的结构特点，建立相应动力计算模型进行了计算及分析。计算结果表明：（1）预制短型浮置板轨道结构对低频荷载的分摊承载能力弱于现浇长型浮置板轨道结构；（2）浮置板交错反相振动的轨道模态对预制短型浮置板轨道结构的振动影响较大，但对现浇长型浮置板轨道结构的振动几乎没有影响；（3）运行列车作用下，现浇30m长板浮置板轨道的钢轨及浮置板响应在30～100Hz频段内大于预制3．6m短板浮置板轨道，但预制3．6m短板浮置板轨道的钢轨及浮置板响应在25Hz以下的大部分频段却大于现浇30m长板浮置板轨道；（4）相较于现浇长型浮置板轨道，预制短浮置板轨道应采用疲劳寿命更长的隔振器。
