The primary step in the thermal decomposition of DNOAF is the disconnection of C-N bond between the furazan rings, followed by the step for the opening of the furazan rings.

在实验基础上提出了DNOAF的热分解历程，DNOAF的热分解首先发生在呋咱环间的C-N键，然后是呋咱环的开环分解。

In this paper, not only the mechanism of thermal degradation of polylactide is introduced, but also the kinds of metal catalysts, their influence on L-lactide formation and racemization through thermal degradation of PLLA are referred.

本文介绍了聚乳酸热降解的反应机理，详细阐述了添加的金属催化剂的种类，及其催化PLLA热降解生成L-丙交酯及发生消旋化作用的机理。

The results have shown that P-RE-USY has good hydrothermal stability owing to the migration of hydroxy rare earth cation from the super cages to the sodalite cages enhanced by phosphorus addition, inhibiting the frame...

结果表明，由于磷促进了稀土离子由超笼向方钠石笼中的迁移，阻止了沸石在水热条件下的脱铝作用，从而改善了P RE USY沸石的水热稳定性；P RE USY沸石酸性分布更集中在中强酸范围，有利于发生氢转移反应，而强酸数量的降低有利于减少焦炭形成，改善了焦炭选择性。

Heat flux increases remarkably in spring, so layering comes into being gradually and concentrates on the central BS where tidal mixing is weak; whether the range or intensity culminates during the Summer Solstice; stratification is weakened in accompany with the decrease of heat flux in the fall, and is still apparent in BS strait; the gale enhances vertical stirring of sea water, so no obvious stratification exists in winter.

春天海表热通量显著增强，层化结构也开始形成，主要分布在潮汐混合较弱的中央水域；夏至时节层化结构无论是发生范围还是层化强度都达到极致；进入秋季，层化强度伴随着海表热通量的减少而削弱，分布区域也逐步向渤海海峡转移；冬季大风进一步增强了海水的垂向混合，此时渤海不再有垂向分层。

Little overdose aluminum caused that the displacement reaction occurred between Al and TiO2 with releasing much heat, and Al2O3 and free Ti were formed, then the active Ti combined with C and produced TiC; more overdose aluminum caused the thermit reaction happened between Al and TiO2, and was generated, then Al3 Ti combined with C and produced TiC.

首先在无过量铝的情况下，Al与TiO2发生置换反应，生成了Ai2O3和游离态，而后游离态与C结合生成TiC；而存在过量铝的情况下，首先发生铝热反应生成Al3Ti，进而Al3Ti与C结合生成TiC。最终完全获得Ai2O3-TiC/Al复合材料。

FTIR analysis was performed on the thermally aged inhibitors to check for any change in molecular symmetry that would indicate thermal degradation.Where crystallisation had occurred,there were obvious differences in spectra with key active inhibitor component peaks.

红外光谱分析等进行了热老化抑制剂检查任何改变，将分子对称的热降解那里发生了crystallisation有明显的差异，在光谱峰与关键部件。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
