不燃的

There's no need to burn out at the beginning.

而且不需要在一开始就燃尽你所有的能量。

Thus,in experiments of water mist flashover restraining, consideration only the mist decalescence in smoke and flame would be enough and doable.Nonlinear dynamics was chosen here for investigating water mist flashover restraining.

雾滴冷却汽油池火燃料表面效果不佳，因而在构建细水雾抑制轰燃预测模型时可以忽略燃料表面冷却，仅考虑雾滴在烟气层和火焰区的吸热效果。

It is because that detonation and deflagration waves cannot propagate in the same direction when f is convex.

这是因为在流函数为凸的条件下，爆轰波只能是前向波而爆燃波只能是后向波，它们不能在同一方向上传播因而也就不可能出现上述转化。

In the flashover zone, an unstable point can be obtained from the characteristic curve and differential coefficient curve of the potential function.

在轰然区，可利用势函数的特性曲线和微商图得出火灾的不稳定点，再由不稳定点取值计算轰燃发生时热烟气层的温度。

This experiment studies the relation of ionic current signals and A/F ratio on different premixed pressure.

通过控制预混压力和空燃比两个参数变化，消除了由于发动机循环变动对燃烧状态和离子电流强度的不稳定影响。

We could not find them to have beliefs about the colours of things in general—we could not ascribe to them beliefs with those contents—by explaining how they form those thoughts from other thoughts they have of things that are not colours, as we might do in the case of phlogiston or goblins.

我们不能发现他们持有关于颜色物的信念——我们不能归给他们具有那些内容的信念——通过解释他们如何从其他那些非颜色东西那里形成颜色信念，就如在燃素或妖精哪里。

In recent years, there has been a resurgence of interest in the development of hybrid rocket engines for advanced launch vehicle applications.

然而由于混合发动机的结构特点，如不采取特殊的措施，混合发动机的燃烧效率和燃面后退速率都很低，因此，开展混合发动机燃烧和燃速特性研究就显得尤为重要。

The experimental results show that the arc unstable processes have many unsuccessful choppings, i. e. arc extinctions and reignitions.

截流前电弧不稳定过程中存在许多不成功截断，即许多次熄弧和熄弧后恢复电压导致的电弧重燃。

I am using fire retardant monomer copolymerized with monomer to generate modified polyester flame retardant polyester chips, then spinning, spinning and other processes to produce a permanent phosphorus flame-retardant polyester woven or knitted fabric, the flame retardant Merit (LOI 34, reach the national standard GB8624-97 flame retardant B1 level), not the loss of permanent flame retardant (flame retardant after washing 50 times the effect does not change), and the dyeing properties of a good, non-toxic smoke when burned, are not with the environment-friendly halogen-free flame-retardant fabric, with ordinary fabrics like soft, beautiful, has good antistatic property.

我公司采用阻燃剂单体与聚酯单体共聚生成改性阻燃聚酯切片，再经纺丝，纺纱等工艺生产出磷系永久阻燃涤纶机织或针织织物，其阻燃性能优异（LOI≥34，达到国家GB8624-97标准难燃B1级），阻燃性永久不丢失（洗涤50次以后阻燃效果不改变），且染色性能良好，燃烧时低烟无毒，属于不含卤素的环保型阻燃织物，与普通织物一样手感柔软，美观，有较好的抗静电性。

At present there exit many problems on pulverized coal combustion technology, for example, poor flame stability (including for low-grade fuels and low load), low combustion efficiency, serious pollution, furnace slagging and high temperature corrosion, etc. Therefore solving these problems is very important for pulverized coal-fired utility boilers.

目前我国煤粉燃烧技术中存在的主要问题是燃烧不稳定（包括劣质煤稳燃和低负荷稳燃）、燃烧效率低、污染严重、结渣和高温腐蚀问题等，解决这些问题是煤粉锅炉安全、稳定、高效和清洁燃烧的基本保证，也是今后煤粉燃烧技术的发展方向。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
