查询词典 hydrogen

The results show that the increasing weight of tungsten oxide nanopowders and the color of tungsten nanomaterials turns light yellow from dark blue and black by increasing oxygen partial pressure in blown gas; the decreasing weight of tungsten oxide nanopowders and the color of tungsten oxide nanopowders becomes dark blue by the plasma that compares row increase including the hydrogen.The tungsten oxide nanomrods was increasing with chamber pressures. Urged nanoparticles to have the clavate fusion phenomenon in the development process with increasing plasma currents, and increased the nanorods distribution quantity along with the generated time to be more, 12 minutes later presents all nanorods. This system to prepare a monoclinic crystal W18O49 nanorods successfully, each hourly output approximately is 0.33 gram, and monoclinic crystal WO3 tungsten oxide nanoparticles, each hourly output approximately is 5.77 grams, its growth mechanism is Vapor-Solid solidly the physiognomy explanation.

研究结果显示，随著氧分压增加时，氧化钨材料呈现重量增加趋势，其颜色从黑色至深蓝色转为淡黄色；随著电浆气中含氢气比列的增加，氧化钨材料呈现重量减少，其颜色从淡黄色至深蓝色转为黑色；针对於氧化钨奈米棒而言随了腔体压力增加，奈米棒的数量也会随之增加，而电浆电流的提高，促使奈米颗粒在成长过程中有了棒状熔合现象，且随了生成时间的增加奈米棒分布数量越多，直到12分钟后呈现出多是奈米棒；本制程在适当制程条件下成功制备出单斜晶体W18O49奈米棒，每小时产量约为0.33 公克，与单斜晶体WO3氧化钨奈米颗粒，每小时产量约为5.77公克，其成长机制可透过气-固（Vapor-Solid， VS）相法解释。
