In this study, the effect of multi-walled carbon nanotubes （MWCNTs） additive on the dehydriding properties of the Zn（BH4）2/NaCl composite prepared by high energy ball milling were investigated. X-ray diffraction （XRD）, Fourier transform infrared spectroscopy （FTIR） results demonstrated that Zn（BH4）2 was produced from mechanochemical reaction between ZnCl2 and NaBH4. Compared with the undoped sample, 10 wt% MWCNTs effectively lowered the decomposition temperature of Zn（BH4）2 by 15 ℃. The complex released 3.6 wt% hydrogen within 250 s at 100 ℃ and totally released 4.5 wt% hydrogen within 2500 s, indicating it has a considerable potential as a hydrogen storage material.

为验证内置式颗粒燃烧密集烤房的性能和烟叶烘烤效果,使用内置式生物质燃烧机烤房、外置式生物质燃烧机烤房2种不同类型燃烧机烤房在同一烘烤工艺进行对比试验研究,并与传统燃煤烤房进行对照,从能耗成本、烤后烟叶外观质量、烟叶内在质量等方面对其使用效果进行分析。结果表明内置式生物质燃烧机烤房在烘烤成本、烘烤质量、经济效益、减工降本等方面都要优于燃煤烤房,与外置式生物质燃烧机烤房原理类似。内置式生物质燃烧烤房和外置式生物质燃烧烤房设备均为烟叶烘烤加热设备,在对原有密集烤房燃烧室进行小面积改造的情况下,即可替代燃煤进行生物质颗粒燃烧,自动供热烘烤烟叶。使用生物质燃料燃烧供热,试验烘烤成本稍高于燃煤烤房,但用工成本有相应减少,燃料较易获取,升温能够满足烟叶烘烤需要,污染小,属于国家鼓励推广的低污染能源,在新建新能源烤房中有较好的推广前景。

A novel metal-enamel interlocking coating was designed and prepared in situ by co-deposition of Ni-enamel composite layer and subsequent air spray of enamel with 10 wt% nanoscale Ni. During the firing process, the external enamel layer was melted and jointed with the enamel particles at the upper part of the Ni-plating layer to form the enamel pegs. Thermal shock tests of pure enamel, enamel with 10 wt% Ni composite and metal-enamel interlocking coatings were conducted at 600 °C in water and static air. The results indicated that the metal-enamel interlocking showed superior thermal shock resistance to both pure enamel and enamel with 10 wt% Ni composite coatings. The enhanced performance was mainly attributed to the advantageous effects of mechanical interlocking of the enamel pegs formed at the enamel/Ni-plating interface. Meanwhile, during thermal shock test, big clusters formed by nanoscale Ni agglomerations were oxidised to be a Ni/NiO core–shell structure while small single nanoscale Ni grains were oxidised completely, which both improved the thermal shock resistance of enamel coating significantly.

针对激光雷达在长直环境下鲁棒性低以及视觉相机受光照条件影响大的问题,提出一种利用序贯卡尔曼滤波将两种传感器采集到的信息进行融合的定位方法,将传感器作为独立的节点逐级传递以实现多层次滤波,解决了异步传感器更新延迟导致算法中断的问题,同时为算法添加自适应成分,避免了移动机器人长距离行驶过程中因缺少动态调节而产生发散的现象。仿真实验结果表明,以自适应序贯滤波的形式,融合定位结果显著降低了单一传感器测量带来的误差,有效提升了移动机器人在未知环境下的定位精度。
