为研究高压钢制储氢容器在开放空间泄漏后的氢气扩散问题,在建立泄漏氢气组分传输模型和湍流计算模型的基础上,分别对不同内压、不同泄漏孔径、和不同风向风速条件下的氢气稳定扩散浓度场进行模拟和对比分析,结果表明,泄漏孔径的变化对泄漏爆炸区域的影响最为直接,而内压变化影响较小,风速增加有利于扩散.
以邻二氯苄为起始原料,成功合成了锂电池新型正极材料邻二苄基二硫化物(DBD).通过元素分析、氢谱和质谱的表征,表明其组成和结构与理论的相吻合.经循环伏安研究,邻二苄基二硫化物在铂电极上的还原峰(硫硫键的断裂)为-0.44V,氧化峰(硫硫键的键合)为0.28 V,相距0.72V;在玻碳电极上还原峰为-1.1 V,氧化峰(硫硫键的键合)为0.23 V,相差1.3 V;在金电极上氧化还原峰峰间距更大.这
本世纪以来,受全球能源供应紧张和气候变化等影响,风力资源作为一种清洁能源和可再生能源的综合利用受到世界性的广泛关注和实践.中国西部的河西走廊是著名的"丝绸之路"中断,同时号称"世界风库",以风能为主的可再生资源丰富,较适合发展以风电为主的新能源产业.随着全国首座千万千瓦级风电产业基地第一期工程完工和2010年11月3日正式向大电网送电,河西走廊"建设大基地、融入大电网"的风电产业进入了规模开发和快
Pullulanase and pectinase, cooperating with two enzymes methods, can increase starch degradation rate and reducing sugar content in the fermentation liquor.The fermentation liquor also has a low lique
An in situ alkaline transesterification process of rapeseed filter cakes with methanol assisted by petroleum ether was described in this article.Petroleum ether served as co-solvent and extraction sol
A new diatom strain MD1 was isolated from seawater Spirulina culture at Guangzhou, China, and identified as Nitzschia sp.MD1.The biotechnological potential of MD1 was assessed through observation and
An Exergo-economics mathematical model for heat integration across plants is presented.The model is considered total cost of integrated heat exchanger network (HEN) and long distance matches.The paper
Yan Taiwan cracked rock slope was formed by the repeated regional geological structure.The complex and ever-changing conditions of engineering geology has brought great difficulties to engineering des
Methane fermentative residues (MFR) can be applied to control almost 30 common crop diseases and insect pests of farmlands.They show noticeable control effects on at least 20 crop diseases and farmlan
This study determined the biogas production potential of different mixtures of dairy manure and food waste under mesophilic conditions (35℃) and compared them with the yield from manure or food waste
