本文开展了500 J储能下、大气空气介质中微秒脉冲电流源驱动平面型铜丝阵负载电爆炸放电特性研究,并与铜单丝电爆炸进行了比较.实验中保持铜电极间距2 cm不变,选择2-16根直径100μm的铜丝组成平面型铜丝阵,同时选择直径50-400μm的单根铜丝作为对照,对电爆炸过程中负载电压、回路电流与光辐射强度进行测量,计算得到电功率、沉积能量等参数,研究质量变化对铜导体电爆炸过程的影响规律;特别地,对于相同质量下单丝与丝阵负载情况进行比较.实验结果表明,随着质量增加,单丝电爆炸气化与电离过程变缓,宏观表现为电压峰值时刻延后、半高宽增大(约0.07μs增至约0.64μs);与之不同,虽然丝阵电爆炸时刻随质量增加延后,但气化与电离持续时间变化不明显,电压峰半高宽稳定在0.11±0.01μs,且击穿发生前丝阵负载沉积能量低于同质量单丝负载.光辐射强度方面,丝阵电爆炸光辐射强度比三次同质量下单丝电爆炸分别强约28%,49%和52%.造成单丝与丝阵电爆炸过程差异的原因可能有两个方面:一是比表面积的差异使得细丝的相变过程更加迅速,表现为相同质量下细丝丝阵比粗单丝爆炸过程快;二是电热/磁流体不稳定性在丝阵与单丝中发展程度不同,表现为光强-时间曲线的差异.

Zeolite nanosheets with a short b-axis thickness are highly desirable in lots of catalytic reactions due to their reduced diffusion resistance. Nevertheless, conventional synthesis methods usually require expensive structure-directing agents(SDAs), pricey raw materials, and eco-unfriendly fluorine-containing additives. Here, we contributed a cost-effective and fluoride-free synthesis method for synthesizing high-quality MFI zeolite nanosheets through a Silicalite-1(Sil-1) seed suspension and urea cooperative strategy, only with inexpensive colloidal silica as the Si source. Our approach was effective for synthesizing both Sil-1 and aluminum-containing ZSM-5 nanosheets. By optimizing key synthesis parameters,including seed aging time, seed quantity, and urea concentration, we achieved precise control over the crystal face aspect ratio and b-axis thickness. We also revealed a non-classical oriented nanosheet growth mechanism, where Sil-1 seeds induced the formation of quasi-ordered precursor particles, and the(010)crystal planes of these particles facilitated urea adsorption, thereby promoting c-axis-oriented *** obtained ZSM-5 nanosheets exhibited exceptional catalytic performance in the benzene alkylation with ethanol, maintaining stability for over 500 h, which is 5 times longer than traditional ZSM-5 catalysts. Furthermore, large-scale production of ZSM-5 nanosheets was successfully carried out in a 3 L highpressure autoclave, yielding samples consistent with those from laboratory-scale synthesis. This work marks a significant step forward in the sustainable and efficient production of MFI nanosheets using inexpensive and environmentally friendly raw materials, offering the broad applicability in catalysis.

【目的】研究不同氮肥类型下缓释氮肥与尿素掺混对3个不同冬小麦品种生长发育、干物质累积量、产量、氮素转运、吸收利用效率以及土壤硝态氮残留的影响,探索适宜提高陕西关中地区冬小麦产量的氮肥配比,为该地冬小麦高效生产的肥料管理提供科学依据。【方法】本试验设置了4个氮肥处理,分别为纯尿素(U)、纯缓释氮肥(S)、缓释氮肥与尿素8∶2掺混(SU1)、缓释氮肥与尿素6∶4掺混(SU2),施氮量为180kg/hm2;以不施氮肥(N0)为对照。选取关中地区农民主栽的3个冬小麦品种[小偃22(XY22)、西农979(XN979)和郑麦379(ZM379)]为试材,每个品种设5个处理。观测冬小麦在主要生育期的株高和叶面积指数,并分析冬小麦成熟期的干物质累积量、产量、植株氮素累积量和土壤硝态氮残留量。【结果】施氮量相等时,缓释氮肥与尿素掺施能显著促进冬小麦生长发育,增加冬小麦的产量和成熟期植株氮素累积量。SU2处理下不同冬小麦品种的株高、叶面积指数、产量和成熟期植株氮素累积量均达到最大值,且0—100 cm土层剖面硝态氮残留量最小。SU2处理下3个冬小麦品种的产量分别比U和S处理提高了31.81%~31.99%和9.66%~25.38%;营养器官的氮素向籽粒的转移率也分别提高了21.31%~51.12%和2.60%~20.78%。此外,缓释氮肥与尿素掺施能显著提高3个冬小麦品种的氮素吸收利用效率,显著促进开花后营养器官的氮素向籽粒转运,XY22、XN979和ZM379在SU处理下,冬小麦营养器官氮素转运对籽粒的贡献率分别为49.71%、48.32%和49.39%;在SU2处理下3个冬小麦品种的氮肥农学利用率和氮肥偏生产力均最大,分别为17.54和41.95 kg/kg、17.94和41.53kg/kg、11.32和38.56 kg/kg。冬小麦收获后,XY22在SU2处理下0—100 cm土层硝态氮的残留总量在3个品种中最小,为112.67 kg/hm2,比U处理下的硝态氮累积总量明显下降13.48%。这表明缓释氮肥与尿素掺施可以显著提高表层土壤硝态氮含量,减少硝态氮向土壤深层淋失,提高氮肥的利用效率。【结论】施氮量为180kg/hm2时,缓释氮肥与尿素按6∶4掺混是本试验条件下冬小麦高效生产的最佳掺施比例。
