抗爆

Anti-knock additive tetraethyl lead,vapor pressure,cetane number and content of aromatic hydrocarbon,ethylenes,sulfur and oxides respectively in the motor fuel are more detailedly analysed in regard to their effect on motor vehicle exhaust emission.

较为详细地分析了燃油中四乙铅抗爆剂、芳烃含量、烯烃含量、硫含量、蒸气压、十六烷值及含氧化合物等对汽车排放的影响，并简述了其发展趋势。

We have not found any reports that o-toluidine and N,N-dimethylaniline can be used as antiknock. The electrochemical properties of aromatic amine are in line with its' antidetonating quality and actual application.

而实际上采用胺类化合物作抗爆剂时，一般使用N-甲基苯胺、苯胺、邻甲苯胺及间甲苯胺，尚未见到使用对甲苯胺和N，N-二甲基苯胺的报道。

The corrugated steel, frameless structure proved to be most blast-resistant of those tested.

槽纹钢板无架结构经事实证明是试验中最能抗爆震波影响的。

However, hunkering down in a blast resistant or brick building and staying away from windows can help your odds.

然而，静待在抗爆物，或砖建筑物和远离窗户，可以帮助您的胜算。

And the lives near the tunnel also will be menaced by the threat of explosion.

爆炸时隧道衬砌结构的稳定性是隧道安全与周围结构物安全的基础，为了解在隧道内爆炸事故引发的衬砌结构动力响应规律，探讨隧道衬砌结构的损伤状况，对盾构隧道衬砌结构抗爆具有深远的意义。

Because of its nonpoisonous, DMC can substitute phosgene , dimethyl sulfate or methylating used as methyl pharmaceutical to improve the security of production and reduce the environmental pollution; As the solvent, DMC can substitute fluorine lyons , methyl chloroform , trichloroethylene , benzene , dimethylbenzene, etc.. And it can be used as the paint dope, clean solvent. As gasoline additive, DMC can raise hard octane value and oxygen content and improve its antiknock possibility.

由于DMC无毒，可替代剧毒的光气、硫酸二甲酯等作为甲基化剂或羰基化剂使用，提高生产操作的安全性，降低环境污染；作为溶剂，DMC可替代氟里昂、三氯乙烷、三氯乙烯、苯、二甲苯等用于油漆涂料、清洁溶剂等；作为汽油添加剂，DMC可提高其辛烷值和含氧量，进而提高其抗爆性。

With the special contact ability of LS-DYNA, the numerical simulations show the contact relationship between the door and the frame, the door blot and bearing, respectively.

同时，充分利用 LS-DYNA 提供的强大的接触分析功能，真实模拟了抗爆门和门框，门轴之间的接触关系。

Particularly in the production of high-octane gasoline brands, alone Change processing technology and high-octane blending more difficult are generally used by adding an appropriate amount of ANTIKNOCKS solution.

如美国、欧洲就不准在无铅汽油中使用含铁燃料添加剂。非金属抗爆剂如MTBE，尽管近年来国内普遍采用，因其不能使其充分燃烧会产生致癌物而将被限量使用。

The engine ran on a special mixture of methyl alcohol (63%), benzene (16%), ethanol (12%), acetone (4.4%), nitrobenzene (2.2%), avgas (2%), and ether (0.4%) with MW (methanol-water) injection for charge cooling and as an anti-detonant.

特别混合物燃料为引擎运转提供动力，甲醇(63%)，苯(16%)，对氨基苯甲酸二(12%)，丙酮(4.4%)，硝基苯(2.2%)，飞机用燃料(2%)和乙醚(0.4%)，以100W充电冷却射入并作为抗爆剂。

For leting drop quality fuel plenty of normal heptane have no lead tetraethyl ,Therefore be unlikely there not be the lead pollution .

因为低品质燃料多含正庚烷而不含抗爆剂四乙基铅，所以不会有铅污染。
