HNS-IV(Hexanitrostilbene-IV) is the main charge of the exploding foil initiators(EFI), and the microstructure of the HNS will directly affect its density, flowability, sensitivity, and stability. HNS microspheres were prepared using droplet microfluidics, and the particle size, morphology, specific surface area, thermal performance, and ignition threshold of the HNS microspheres were characterized and tested. The results shown that the prepared HNS microspheres have high sphericity, with an average particle size of 20.52 μm(coefficient of variation less than 0.2), and a specific surface area of 21.62 m^(2)/g(6.87 m^(2)/g higher than the raw material). Without changing the crystal structure and thermal stability of HNS-IV, this method significantly enhances the sensitivity of HNS-IV to short pulses and reduces the ignition threshold of the slapper detonator to below 1000 V. This will contribute to the miniaturization and low cost of EFI.

以双氰胺、甲醛为原料制备双氰胺甲醛（DDF）缩聚物，并研究DDF用作造纸助留助滤剂的可行性。探讨DDF用量、浆料pH值、混合时间及DDF与填料碳酸钙添加顺序4个因素对浆料助留助滤性能的影响，并通过扫描电子显微镜对DDF和阳离子聚丙烯酰胺（CPAM）在纸张中的留着情况进行了对比。实验结果表明，当先加入用量0．03％的DDF、再加入20％碳酸钙、浆料pH值9、混合时间6～7min时，浆料可获得较好的助留效果，但助滤效果不明显；扫描电子显微镜结果表明，碳酸钙和细小纤维在DDF作用下絮聚成体积较大的絮团，留着在纤维交织层中，从而提高了填料和细小纤维的留着率。
