查询词典 high up in the air

Asked the American people why the United States Air Force equipment is extremely advanced and the security sector can not stop the hijacked aircraft, but also some scientists questioned: jet flame produced by combustion is not sufficient completely destroyed the structure of the twin towers, can not lead to the twin towers Finally, all the collapsed World Trade Center in ruins and found a high temperature molten metal is caused by thermite, it is very likely infer a person the use of explosives blew up the twin towers.

美国民众问道，为什么装备极其先进的美国空军和安全部门无法阻止被劫持了的飞机，也有科学家质疑：喷气式客机燃烧时产生的火焰不足以完全破坏世贸双塔的结构，不能导致双塔最后全部坍塌，而且在世贸中心废墟上发现的熔化金属是一种高温铝热剂所致，因此推断极有可能是某人使用炸药炸毁了双塔。

Tangshan City, the old single-storey houses for the old-fashioned, turned into rubble after the earthquake; the new urban area are multi-storey brick-concrete structure buildings, wiped out almost collapsed; reinforced concrete frame structure is also not spared the high-rise buildings, railway track occurred in snake shape distortions or subsidence as a result of the roadbedcheng bo lang style ups and downs, have a large surface cracks, the general collapse of a bridge destroyed, seismotectonic cracks extended up to 8 kilometers, with cracks near the ground motion is very alarming, two of its more than 200 meters within the scope of even the people air have been thrown.

唐山市老区多为老式单层民房，震后变成一片瓦砾；新市区大多是砖混结构多层建筑，几乎倒塌殆尽；钢筋混凝土框架结构的高层建筑物亦未能幸免，铁路轨道发生蛇形扭曲或由于路基下沉而呈波浪式起伏，地表产生宽大裂缝，桥梁普遍塌毁，地震构造裂缝延伸达 8公里，裂缝带附近的地面运动非常惊人，其两则200多米的范围内连人都被抛向空中。

Hillside other a side is a big high mountain that is crossed by hill baked wheaten cake cypress, withered the curl up like dead truncal Qiu snake is in upper, in deadwood clump, the flower of tuft bunch yellow is swaying in air cooling frivolous the leaf that is like paper.

山坡另一侧是一大片被山火烧过的高山柏，枯死的躯干虬蛇般蜷伏在地表，枯枝丛中，一簇簇黄色的花朵在冷风中摇曳着轻薄如纸的花瓣。

In applying high concentration burning technique to improving burning efficiency for pulverized coal burner, for studying the effect of solid flows of different concentration on burning, Euler mathematical model is set up using gas-solid two phase flow theory. The paper describes the low concentration pulverized coal in horizontal primary air pipe. The relationship between the velocity and concentration of gas phase and that of solid phase, and the effect of gas flow velocity on gas-solid two-phase flows, is arrived through calculating the flow field. Reasonable gas flow velocity is proposed.

在应用高浓度燃烧技术提高煤粉炉的燃烧效率时，为了研究不同浓度固相流动对燃烧的影响，应用气固两相流理论建立Euler数学模型对一次风水平管道中低浓度的煤粉颗粒进行了描述，通过求解流场，得到了管内气相和固相的速度和浓度的分布关系，及其气体流速对气固两相流动的影响，并提出合理气流速度。
