火焰

This paper superimposes the impact of the wind on the flame's basic trajectory to simulate the surface movement.While ensuring the consistency and continuity of the flame texture,it reduces the number of particles to enhance real-time rendering.Besides,the fidelity of simulation and adaptability under different scenarios are enhanced by implementing the artificial control on the parameters of the wind.

将不受风力时的火焰基本运动轨迹和风力影响相叠加，来模拟多风影响下火焰表面的运动，在保证动态火焰纹理一致性和连续性的同时，减少粒子数量，提高渲染实时性，并实现了风的参数的人为控制，增强了模拟效果的逼真度和在不同场景下的适应性。

The title of my paper is the flame detecting system of Furnace Safeguard Supervisory System..The operation safety of the large scale boiler using coal or gas as the fuel is highly depending on the reliability and stability detections of the burning flame in the boiler.First,the paper summarizes the research background and the current situations on the flame detection system of FSSS in China and abroad, analyzes its future trend of market and technology,and then puts forward my research goals and expected results.and resolved problem.

大型燃煤燃气锅炉的安全运行在很大程度上依赖于锅炉炉膛火焰燃烧的稳定性和可靠性检测，论文首先综述了锅炉炉膛安全保护系统(Furnace Safeguard Supervisory System，以下简称FSSS)中火焰检测系统的国内外研究现状，分析了火焰检测系统的国内市场前景，提出了本课题的研究目标和需要解决的主要问题。

Based on the above two experimental studies,we inferred the main combustion characteristic at high altitude which was that the flame radiation coefficient was obviously lower than that in atmospheric region and the mechanism which was due to higher volume fraction of carbon particles than that under atmospheric pressure.To validate this infer,the focus of last experimental study was on the volume fraction of carbon particles in the flame.

前两部分实验研究我们分析得到高原地区的主要燃烧特性是火焰辐射系数明显低于常压地区，其机理是由于火焰中的碳颗粒体积分数高于常压下的，为了验证这一推断，最后一部分实验研究的重点是火焰中碳颗粒的体积分数。

Process:① the platinum wire dipped in concentrated hydrochloric acid to colorless colorless flame on the ignition;②sample in the colorless flame ignition, to observe the flame color (if test potassium cobalt glass through observation, because in most cases need to be used when the system of potassium sodium, potassium solution, therefore often contain sodium, and sodium yellow flame color reaction, a small amount of yellow and purple, respectively, can not come out).

3操作过程：①将铂丝蘸浓盐酸在无色火焰上灼烧至无色；②蘸取试样在无色火焰上灼烧，观察火焰颜色(若检验钾要透过钴玻璃观察，因为大多数情况下制钾时需要用到钠，因此钾离子溶液中常含有钠离子，而钠的焰色反应为黄色，黄色与少量的紫色无法分别出来)。

In the study, SD2000 spectrometer is applied to obtain radiation spectrum of flame within wavelength 480-1100nm, from which flame temperature and monochromatic emissivity are derived by Newton Raphson non-linear method and Levenberg-Marquart modeling method.

在该方法中，采用SD2000型光纤光谱仪测量火焰在可见光（480-1100nm）波长范围内的火焰的辐射光谱，结合Newton-Raphson非线性迭代算法和Levenberg-Marquardt最优化算法，得到火焰温度和单色辐射率变化规律。

After taking the form of pure fire, Chantico had intentionally removed his flaming arms and reshaped them using his pyrokinesis into three- to four-foot tall copies of himself.

在得到了纯粹的火焰形状后，查安逖克有意地去掉了他的火焰手臂，并用心灵力量把火焰变成了3到4英尺高的小人形状，外形和他自己一样。

In addition, a pilot flame is applied to the bottom corner of the specimen during the first minute of test.

此外，在测试开始后的一分钟内把引燃火焰施加到样品的底角，记下火焰头到达产品上的参考标志所需要的时间，连同火焰在1分30秒和测试终止时的传播的范围记下。

The Flaming Mountains is not fiction, but Huoyanshan non-real flame but the flame of the red sandstone under the hot sun shining shining like the flame just piping hot steam.

而火焰山也并非虚构，只不过火焰山的火焰非真火焰而是烈日下的红砂岩灼灼闪光、热气蒸腾似火焰而已。

In the experimentation, the premixed propane-air flame propagation behavior was studied as the following:(1) Study on pressure wave influence on premixed propane-air flame propagation behavior under different pressure relief case The high speed Schlieren photograph method was used to record the dynamic process of flame propagation clearly, including the precise flame front position, flame structure, and so on.

实验过程中，首先利用预混火焰精细实验台对丙烷-空气预混火焰的传播特性进行了实验研究：(1)重点研究了不同泄压条件下的压力波对丙烷-空气预混火焰传播特性的影响。

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）。
