本文从阻燃化学反应、化学键能、热传递和反应动力学角度分析卤素类阻燃剂的阻燃机理。

The flame retardant fundamentals were discussed based on the flame retardant chemical reactions, bond energy, heat transfer and reaction kinetics aspects.

X射线吸收光谱的峰值能显示出目标物质的化学键的确切性质，从而显示其组织结构。

The peaks in the X-ray absorptionspectrum can shed light on the precise nature of the target substance'schemical bonds, and hence on its structure.

如果键能非常强，热能并不足以，打破这些化学键，破坏这些化学键，并使它们液化。

If the bonding energy is very strongly negative, thermal energy isn't great enough to disrupt those bonds and allow those bonds to be broken and then have fluidity.
