焦炭

It has been found that there exists a relationship between the coking rate and regeneration rate of the catalysts.

在再生过程中，催化剂本身对焦炭的燃烧速度基本没有影响，可以看作为惰性物。

他说，中国煤炭火力发电厂和焦炭厂排放的铅比电池行业要多得多。

An integral part of the history, mentality and romance of a people, rum's place in the world is, perhaps, just a bit too heavy to contemplate while languidly sipping on a pina colada or a rum and coke.

不可分割的一部分的历史、心理和浪漫的人，朗姆酒的地方是，也许刚刚有点太沉重迎面而懒洋洋呷了皮纳colada或朗姆酒和焦炭。

By a series of contrastable experiments, the influences of coal stamping operation, the grain size of mixing coals, coking time, coke quenching type and coal blending composition on thermal properties of coke were discussed.

通过试验对比，探讨了炼焦煤捣固操作、配合煤细度、结焦时间、熄焦方式以及配煤结构对焦炭热态性能的影响。

Some factors to influence the silicon content of hot metal were proposed on the basis of the experiment in the lab: increasing the binary basicity is favorable to desiliconization; the oxide in slag debases the silicon activity and is of great advantage to desiliconization; Al2O3 and SiO2 are disadvantageous to desiliconization, the volatilization content of SiO2 in coke increases with increasing smelting temperature, leading to increase the silicon content of hot metal; the silicon content of hot metal increases with increasing the drip zone's altitude.

在实验室进行了降低铁水中硅含量的实验，得到了铁水中硅含量的影响因素：提高二元碱度有利于降硅；增加渣中氧化物可降低SiO2的活度有利于降硅；Al2O3和SiO2不利于降硅；冶炼时焦炭中SiO2的挥发量随温度的升高而增多，使铁水中硅含量增加；随着滴落带高度的增加，铁水中硅含量不断增加。

The mathematical model of deflagration to detonation transition for coke p owder and oxygen mixture in one-dimensional closed system was established on th e basis of chemical reaction and two-phase reaction fluid mechanics theory. Num erical simulation of the process was successfully made through coordinate transf ormation and two-step display differential schemes.

This applies also to exter nal stockpiles of coal, pet-coke, ty res and the like, where appropriate fire

储存燃料必须遵守当地消防法规的要求。这同样可以应用于煤，焦炭，轮胎等的储存，尤其时在

Organic: dihydroxybenzene, oxalic acid, hydroquinone, fumaric acid, gulonic acid, o-dihydroxybenzne; m-dihydroxybenzene; coke powder, tartaric acid, cyanuric acid, G salt, R salt.

Good thermal stability and self-extinguishing behavior was observed with the cured polybenzoxazine resins. Second, furan-containing benzoxazine monomers, P-FBz, BPA-FBz, and 4FP-FBz were prepared using furfurylamine as a raw material. Formation of furfurylamine Mannich bridge networks in the polymerizations of P-FBz and BPA-FBz increased the cross-linking densities and thermal stability of the resulting polybenzoxazines. P-FBz and BPA-FBz- based polymers also exhibited high glass transition temperatures above 300℃, high char yields, and low flammability with a limited oxygen index value of 31. The dielectric (Dk3.21–3.39) and mechanical properties (high storage modulus of 3.0–3.9 GPa and low coefficient of thermal expansion of 37.7– 45.4 ppm) of the P-FBz and BPA-FBz-based polymers were superior or comparable to other polybenzoxazines. 4FP-FBz used for polybenzo- xazine modification by means of formation of benzoxazine hybridation with P-FBz.

第二部份以2-呋喃甲胺为起始物，制备了P-FBz、4FP-FBz与BPA-FBz 三个含呋喃官能基之氧代氮代苯并环己烷的单体；BPA-FBz与P-FBz於开环聚合中形成之Mannich bridge网状结构有效地提升聚氧代氮代苯并环己烷聚合物之交联密度与热安定性；Poly与Poly具有大於300℃之玻璃转移温度、高的焦炭生成率与具有31之极限氧指数(Limited oxygen index， LOI)的难燃性特质，Poly与Poly之介电常数(Dk=3.21~3.39)与机械性质[3.0~3.9 GPa的储存模数与37.7~45.4ppm之低热膨胀系数( Low coefficient of thermal expansion， Low CTE)]均较其他聚氧代氮代苯并环己烷为优；4FP-FBz具有低之介电常数(Dk=2.7)，以其作为降低介电常数之反应型改质剂，与P-FBz混成，证实可有效地降低Poly的介电常数。

Then, an English ironmaker called Abraham Darby discovered how to do the job with coke.

后来，一位叫亚伯拉罕？达比的英国铁匠发现用焦炭也能制成煤。

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）。
