火焰

Comparing with the traditional high velocity oxygen-kerasense flame spraying, the development of the DZ9000E high velocity oxyfuel spraying is emphasizing on reduction of the cost of coatings and removability of in-situ application under various working conditions.

与氧煤油超音速火焰喷涂系统相比，DZ9000E型氧燃气超音速火焰喷涂系统的开发更侧重于降低涂层的成本以及适应不同工况中现场使用的可移动性。

To study the effects of the obstacle on flame propagation and flame inner structure in methane/air explosion, the effects of the mesh are studied by high speed photograph and schlieren photographs from the microscopic view, and numerical simulation is build.

通过高速摄影与纹影方法从细观角度研究了网状障碍物对管道内瓦斯爆炸火焰细微结构的影响，以及火焰加速机理，并进行了数值模拟。

Observe for a total of up to 30 min from commencement to establish the presence of progressive smouldering.

如果火焰在移开火源后燃烧超过120秒，或者火焰烧到了样板的末端，则记录失败。

Even the near-colorless flames, a new wire on the ignition, the beginning of the flame is yellow, it is difficult to explain is the flame of sodium ions alcohol lamp, or the original color of the flame.

即使是近乎无色的火焰，一根新的铁丝放在外焰上灼烧，开始时火焰也是黄色的，很难说明焰色是钠离子的还是原来酒精灯的焰色。

Based on the conversation equations for hydrodynamics and chemical reaction dynamics, by adopting the k-e turbulent model and the EBU-Arrhenius combustion model, the SIMPLE algorithm was used to investigate numerically the methane-air premixed gas vented explosion process in the two-dimensional space of the spherical vessel with a conduit for explosion venting.

为了得到球形容器内可燃气体的泄爆强度产生机理以及燃烧火焰与压力传播的基本规律，从流体力学和化学反应动力学守恒出发，采用κ-ε湍流模型和EBU-Arrhenius燃烧模型，利用SIMPLE算法对带泄爆导管的球形容器二维空间内甲烷－空气预混气体的泄爆过程内外场进行了数值计算，获得了气体燃烧过程中火焰和压力传播特性以及气体流动特性，能够比较清晰地反映泄爆的整个过程。

II: ① take a thin wire, one end with sand paper wipe, and then lightson alcohol to non-yellow flame ignition,② wire with the end of the water dip, and then dip a number of sodium chloride or anhydrous sodium carbonate powder,③ ignited a new spirit lamp (lamp wick is clean, pure ethanol),④ the stained sodium salt powder on the wire on the ignitiontip, when there is a sharpsmall yellow flame, which is sodium flame.

方法二：①取一条细铁丝，一端用砂纸擦净，再在酒精灯外焰上灼烧至无黄色火焰，②用该端铁丝沾一下水，再沾一些氯化钠或无水碳酸钠粉末，③点燃一盏新的酒精灯，④把沾有钠盐粉末的铁丝放在外焰尖上灼烧，这时外焰尖上有一个小的黄色火焰，那就是钠焰。

Based on experimental study results and theoretical analysis,a way of raising calculation accuracy is being suggested,which applies the tricolour based monochromatic method of mullticoloured CCD,and moreover by means of a certain number of reference points.

通过试验研究和理论分析，提出了一种基于彩色CCD三基色的单色法，测量了气化炉火焰温度，并计算气化火焰二维温度场。

Designer :wolf udo wagner The 'fireplace' collection is an urban interpretation of a campfire and it is safe for use both indoors and outdoors. made from fire resistant glass and stainless steel, fires can last up to 2 and a half hours, emitting little carbon dioxide. What home is complete without a warm, inviting fireplace?

这几款新式壁炉适合城市住宅，它的旋转火焰无论是在室内还是在室外都是安全的，选用的材质是防火玻璃和不锈钢，火焰可以持续燃烧2-2.5小时，只挥发很少的二氧化碳，我们能够想象一个没有壁炉的房子是怎样的吗？

Light holds between its hands The white hill and black oaks, The path that goes o, The tree that stays; Light is a stone that breathes By the sleepwalking river, Light: a girl stretching, A dark bundle dawning; Light shapes the breeze in the curtains, Makes a living body from each hour, Enters the room and slips out, Barefoot, on the edge of a knife; Light is born a woman in a mirror, Naked under diaphanous leaves, Chained by a look, Dissolved in a wink; It touches the fruit and the unbodied, It is a pitcher from which the eye drinks clarities, A flame cut in blossom, a candle watching Where the blackwinged butterfly burns; Light opens the folds of the sheets And the creases of puberty, Glows in the fireplace, its flame becomes shadows That climb the walls, yearning ivy; Light does not absolve or condemn, Is neither just or unjust, Light with impalpable hands raises The buildings of symmetry; Light escapes through a passage of mirrors And returns to light: Is a hand that invents itself, An eye that sees itself in its own inventions.

光 双手拥着白色山峦与黑色橡树林，前行的路，停留的树；光是梦游的河旁呼吸的石光：一个女孩舒展，一束暗色破晓。光勾勒出帘中微风的形状，每时每刻造出一个鲜活的身体，光著脚，踩著刀刃；蹑入房间，又溜走；光是镜中诞生的女人，裸露在透明的叶底，被目光锁定，瞬间消逝；它触摸著果实和无形，眼睛在它的水罐饮著清晰，火焰绽放如花，蜡烛目睹黑翅的蝴蝶燃烧光展开被单的折皱与青春期的皱痕在壁炉里光芒焕发，它的火焰成影在墙上攀爬，怀恋著长春藤光既不赦免也不谴责无公平与不公平而言光，用无法察觉的双手举起对称的建筑；光在镜子的通道里逃遁返回于光：一只发明自己的手，一只在自己的发明中看到自己的眼。

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％。
