1.However, simultaneously monitoring nitric oxide, carbon monoxide,hydro-peroxides, nitrites, nitrates, pentane and ethane in the breath, wouldallow a much more definitive diagnosis of asthma.
无论如何,同时地检测呼吸中的氧化一氮、一氧化碳、,过氧化氢物、亚硝酸盐、硝酸盐,、戊烷和乙烷,将能对哮喘做确定性的诊断。
2.Pentane combines advantageous physical and technical properties with good environmental data. As a blowing agent for polyurethane rigid foams, it is suitable for China market.
戊烷作为发泡剂具有良好的物理和工艺性能及合适的环境数据,适合于我国聚氨酯泡沫市场。
3.The separation of n-pentane, n-hexane and n-heptane mixture with the dividing wall column(DWC) was simulated with commercial software HYSYS, and the optimized operation region was obtained.
以正戊烷、正己烷和正庚烷为分离物系,在简捷计算结果的基础上,利用商业模拟软件HYSYS研究了进料热状态、进料组成和相对挥发度等进料性质对立式隔板塔操作的影响。
4.The catalytic activity and selectivity of the catalysts for n-pentane isomerization at ambient temperature were investigated.
考察了所制备的催化剂上常温下正戊烷异构化反应的活性和选择性。
