查询词典 preheats

The conducting wall in micro-tube preheats the inlet mixture by axial heat transfer. The existence of conducting wall will help to reach full reaction in the micro-tube. As the inlet velocity increases, both the existence of the surface catalytic combustion and the gas phase combustion become the limiting factors on combustion. Wall material and equivalence ratio of hydrogen/air mixture have important influence on catalytic combustion of hydrogen.

计算结果表明：表面催化反应对空间气相反应有抑制作用；在微型管道内，通过导热壁轴向间的传热，预热入口混合气体，使氢气燃烧更加充分；随着入口速度的增大，燃烧过程同时存在着表面催化反应和空间气相反应两种控制因素；管壁材料和当量比对氢气的催化燃烧过程有重要的影响。

Top sintering material preheats for a short time、sinter at lower temperature、cools too fast and has low crystallinity, especially, network SFCA offorms difficultly in the top layer, that results in high ratio of pore, so the strength of top sinter is low. when thickness of sintering material is increased, the ratio of top sinter will be decreased, in its entirety, the strength of sinter will rise.

5烧结矿破碎属脆性断裂，一般在单轴压缩应力下受剪切产生，本文基于低氟烧结矿物质组成，导出了基体抗压强度与烧结矿物质组成的关系式，由此得出，基体抗压强度受磁铁矿影响不大，而受铁酸钙影响较为显著。

The technology also couples with the process of carbon-containing materials coking and calcium-containing materials calcining, preheats the materials to 500-1500 DEG C utilizing the combustion of by-products CO of the carbide preparation and the assistant fuel, thereby further reducing the oxygen and energy consumption of the carbide preparation.

该工艺还与含炭原料焦化和含钙原料煅烧过程耦合，利用电石生产副产物CO以及辅助燃料的燃烧将原料预热至500-1500℃，进一步降低电石生产氧耗及工艺能耗。

Be able to explode ignites （3000Till 4000 ℃,This also is living over-dose air and the numeric value when possesing remains waste gas only ,In case according to the ideal air/fuel ratio layout ,There is not waste gas ,The temperature gathering is taller ）Oil30 grams may be cause （90℃ tail gas preheats ）Steamization （Vaporization heat 2282.7J\g ）……At the respect of the pressure swelling ,Even if being in the critical of water （374℃）Condition ,Critical pressure 21.83MPa of water 、Carbon dioxide critical（31.1℃）Pressure 7.38MPa also is some -fold of a rule piston style explosive motor pressure 5--9MPa （Dalton's Law or the Law of Additive pressures）……For emploing the capacity means difference ,Therefore the composition is different as black and white .

一克爆燃（3000至4000摄氏度，这也只是在过量空气和有残余废气时的数值，如果按理想空燃比配置，没有废气，温度会更高）的油可以使30克（90摄氏度尾气预热）的水汽化（汽化热2282.7J\g）……从膨胀压力方面来说，即使处于水的临界（374摄氏度）状态，水的临界压力21.83MPa、二氧化碳的临界（31.1摄氏度）压力7。 38MPa也是常规活塞式内燃机压力5--9MPa的几倍（压力叠加定律，道尔顿定律）……因为用能方式不同，所以结构就截然不同。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
