针对宁波海相淤泥质软土开展现场模爆试验,获得了不同装药量和埋深条件下软土的孔隙水压力、冲击压力及温度的时程分布和演化规律,揭示了爆炸作用下软土中渗流、应力和温度的耦合现象。试验结果表明:随着药量增大,超静孔隙水压力峰值增大,爆炸后数分钟内孔隙水压力消散较快,随后变慢。爆炸后,软土中冲击波向弹性波转化存在一个分界压力,这个分界压力与介质性质有关系,尤其是含气量。温度在软土介质中具有一定的传导时间和上升时间,且在软土介质中的上升较空气中慢。最后,利用相关理论开展计算,并与实测结果进行了对比分析。研究结果可以为沿海软土地区地下人防工程设计及地基压密处理提供参考。

This paper demonstrates a facile solar steam generator for the generation of high-temperature steam at ambient pressure. The steam generator consists of a coiled copper tube(CCT) that serves as both solar collector and vapor heater. Both the inner and outer surfaces of the CCT are coated with black superhydrophobic copper oxide layer to improve the solar absorption, and such superhydrophobic layer prevents the condensation and clogging of water vapor during the heating process. Solar vapor is generated at the inlet of CCT through interfacial evaporation and subsequently heated inside the CCT as the vapor travels from the inlet to the outlet. By employing this approach, steam temperature that exceeds 100℃ under 1-sun illumination is demonstrated. Furthermore,steam temperature could reach as high as 250℃ under 10-sun illumination at ambient pressure. Successful sterilization experiment was also performed in this work to demonstrate the potential application of the high temperature steam generated. Such demonstrated approach helps open up the potential usage of solar-driven interfacial evaporation in applications that involve high-temperature steam, including medical sterilization,chemical manufacturing and food processing.

研究了应用于全相位频谱分析的正弦波频率估计算法。首先分析了全相位频谱的结构,给出全相位频域插值公式。当信号真实频率位于两相邻量化频率点的中心区域时该公式精度较高,而接近量化频率点时精度较差。根据这个特点,对信号进行频移使新信号的频率落入中心区域再进行频率估计,得到修正频域插值公式。与现有的全相位频率校正算法比较,频域插值算法具有更高的估计精度,在中低信噪比时表现出更佳的性能。
