您要查找的是不是：
- Table 6 indicates the magnitude of the flammability range of SiH4 and H2 blends of NF3, O2 and air, respectively. 表6说明了SiH4和H2分别在NF3、O2和空气中的混合物的可燃范围的大小。
- The wide flammability range, 4% to 74% in air, and the small amount of energy required for ignition necessitate special handling to prevent the inadvertent mixing of hydrogen with air. 在空气中氢的易燃范围很宽，从4%25到74%25，而且点燃所需的能量很少，必须特别处理，以防止无意中把氢和空气混合在一起。
- You have to put the burnt-out ratio control in flammable materials flammability range. 必须要把燃空比控制在易燃材料可燃极限的范围内。
- Hydrogen and air mixtures, within the flammable range, can explode and may burn with a pale blue, almost invisible flame. 在可燃范围内的氢和空气的混合物可能爆炸，也可能燃烧，火焰是淡蓝色，几乎看不见。
- SCBA is also recommended, but remember, atmospheres that are oxygen-deficient are within the flammable range and should not be entered. 但是记住，SCBA还建议，不要进入在可燃范围内的缺氧空气。
- I was reading a magazine when the phone rang. 电话铃响时我正在看一本杂志。
- The melody still rang in her ears. 那个旋律仍然在她的耳际荡。
- In the event of emergency situations, a fire-resistant suit and gloves should be worn. SCBA is also recommended, but remember, atmospheres that are oxygen-deficient are within the flammable range and should not be entered. 在紧急情况下，应当穿防火服并戴手套。但是记住，SCBA还建议，不要进入在可燃范围内的缺氧空气。
- Flammable gas as defined by the DOT is any compressed gas that either forms a flammable mixture with air at a concentration of less than 13% by volume, or has a flammable range in air wider than 12%, regardless of the lower explosive limit (LEL). DOT对易燃气体的定义是：在体积浓度小于13%25的情况下同空气形成易燃混合物的任何压缩气体，或者不考虑较低的爆炸极限（LEL），在空气中的易燃范围大于12%25的任何压缩气体。
- Their refusal rang the knell of our hopes. 他们的拒绝是我们希望破灭的凶兆。
- He rang off without giving his name. 他名字也未说就挂断了电话。
- Mysteriously, there was no answer when I rang. 真怪，我按了铃，但没人应。
- Caution: The amount of hydrogen gas necessary to produce oxygen deficient atmospheres is well within the flammable range, making fire and explosion the primary hazards associated with hydrogen and air atmospheres. 警告：导致空气缺氧的氢的数量在其可燃范围内，这使得起火和爆炸成为了同氢和大气气氛相联系的主要危险。
- The playground rang with children's shouts. 游戏场上到处都是儿童的喊叫声。
- It has come within the range of practical politics. 这就属于可实施性政治的范围了。
- I rang you but couldn't get through. 我给你打电话，但没有打通。
- We sell a wide range of ales and stouts. 我们出售种类繁多的浓啤酒和黑啤酒。
- Come and see our range of gardening tools. 来瞧瞧我们的成套园艺工具吧。
- I rang you several times but couldn't get through. 我给你打了几次电话,可是没打通。
- I was playing on the piano when the telephone rang. 我正在弹钢琴，电话铃响了。
