您要查找的是不是：
- LFL = lower flammable limit 可燃下限
- The lower flammable limit is listed as 2 percent but testing has shown flammability at levels well below this concentration when various diluents are introduced. 列出的可燃极限的下限是2%25，但试验显示，当引入不同的稀释剂时可燃范围远远低于这个浓度。
- The fuel rich propellant used for the unchoked ram rocket should has high burning rate exponent, appropriate burning rate, low flammability limit and steady combustion properties. 分析结果表明：非壅塞式固体火箭冲压发动机要求贫氧推进剂具有高的燃速压强指数、低的可燃极限和足够好的燃烧稳定性。
- Lower flammability limit of methane 沼气成分燃烧下限
- lower flammable limit 易燃下限
- The lower and upper flammability limits (LFL and UFL) for SiH4 in NF3 are 0.66% and 95.3%, respectively. 在NF3中的硅烷的可燃下限和上限分别是0.;66%25和95
- lower flammability limit 发火下限
- Ambient air temperature and humidity may also have an effect on the flammable limits. 周围环境的空气温度和湿度也对可燃极限有影响。
- Dilution with nitrogen (N2) provides a three-component flammability limit of 2.0% SiH4/2.5% NF3/95.5% N2. 用氮(N2)稀释后的三组分的可燃极限为2.;0%25SiH4/2
- Measurements of ground concentration reveal that as the densimetic Froude number grows, the lower flammability distance (LFD) increases. 但随著下游距离增加，云团持续扩散，使得云团最大浓度之差异性变小。
- As a safety measure, the oxygen inside the system pressure envelope should be reduced below the flammability limit prior to introduction of the process hydrocarbons. 作为一项安全措施，在碳氢化合物引入系统压力密封仓以前，内部的氧气含量应降到燃点以下。
- Sherman recommended that Clarke be disciplined, but higher-ups rejected the idea. 谢尔曼建议对克拉克进行纪律惩戒，但高层拒绝了这个意见。
- Unwaged members pay a lower entrance fee. 无固定收入的人入场费从优。
- A man's voice is usually lower than a woman's. 男子的嗓音通常比女子的低。
- The little boy used to push out his lower lip. 那个小孩以前老要撅起下嘴唇。
- Tom was lying on the lower bunk. 汤姆躺在下铺。
- To achieve safe operating conditions in a system using SiH4 and NF3, dilution with N2 is required to remain outside the flammability limits. 为了在使用SiH4和NF3的系统里得到安全的操作条件，要求用氮稀释，使之保持在可燃极限以外。
- Flammability limits for silane are very unusual in that the diluents can expand the range instead of narrowing the range. 硅烷的可燃极限是非常与众不同的，稀释剂会扩大可燃范围，而不是缩小范围。
- The analysis of the flammability limits of cylindrical flames is made.It is demonstrated that heat loss effects greatly the flammability. 并在此基础上对圆柱火焰的可燃极限进行了研究,结果表明热损失对可燃极限产生很大的影响。
- Any chance of a lower price from you? 你能不能要价低一点？
