查询词典 tris nitro-methane

The high valence and metallic Mo species were all unfavourable to methane aromatization.

催化剂上的积炭是Mo/HZSM-5催化剂失活的主要原因。

After intensive efforts from some catalytic research groups worldwide for about 10 years, many encouraging progress in terms of methane activation and aromatization mechanism have been achieved.

经过近十年的研究探索，在甲烷活化、芳构化机理方面均已取得了重要的成果，并形成了一些主要的观点。

It shows that there are cracking and aromatization reactions of C2,C3and C4 hydrocarbons,but no conversion of methane is found.

结果表明，在不同催化剂上，都会发生C2～C4烃的裂解和芳构化反应，但没有观察到甲烷的转化。

A new model for the autoignition of pilot diesel in the mixture of methane with air was proposed and validated with experiments.

着火模型的基本框架仍然采用Shell模型，但考虑到CH4 对柴油着火过程的影响，修正了Shell模型。

This paper presents a new model describing the autoignition of pilot diesel in the mixture of methane with air for dual fuel engines.

预测发动机的燃烧启动和敲缸都需要研究发动机的着火过程以及开发发动机的着火模型。

The skeleton of the new autoignition model is based on Shell model, which considers the effect of methane on autoignition of diesel.

由于着火过程持续时间较短，仅占湍流燃烧过程的一小部分，因此，在能够充分描述着火过程主要特征的情况下，着火模型应尽量简单，所以，虽然有文献提出了着火过程的详细化学动力学模型，实际上一般倾向用简化的化学动力学模型 [1]，这是Shell着火模型至今仍然得到广泛应用的原因。

A In this research, the barrier layer of methane plasma was first used in the polymer surface flame retardancy.

本研究首次将炭阻挡层的概念用于聚合物表面阻燃的研究中，以期获得阻燃效果。

The result showed that aluminum compounds inhibited the methane-producing activity of anaerobic granular sludge significantly,but the microbe could be acclimated to the toxicity,and the activity could be resumed when aluminum compounds are e...

结果表明，铝盐使厌氧颗粒污泥的活性明显降低，但其毒性可以驯化，且清除铝盐后厌氧颗粒污泥的活性可以恢复。

On earth, 90 percent of the methane in the atmosphere comes from the biochemical activity of life.

在地球上，大气层中90 %的甲烷来自于生命的生物化学活动。

The trigger mechanism of PETM remains obscure. One plausible explanation involves abrupt release of marine methane hydrate. Magma activity and bolide effect are also announced accounting for the occurrence of PETM.

对于PETM的触发机制，主流的观点认为是海底天然气水合物突然释放造成巨量甲烷迅速进入表层系统引发的碳循环系统内部反馈。

He paid $5,000 for this cupcake.

他我这个纸杯蛋糕花了5000美元。

I mean, if you want to, that is

我的意思是，如果你们想吃的话。
