当加热沸石时，由于热膨胀作用，正常的硅氧烷键也会存在张力。
Upon heating the zeolite, the normal siloxane linkage would also experience strain due to thermal expansion.
如果张力超过耐受极限，硅氧烷键就很易在高温下发生断裂并在硅和氧原子上分别形成正负电荷。
If the strain exceeds the tolerable limit, the Si-O-Si linkage can break easily at high temperature and lead to the creation of positive and negative charges on silicon and oxygen atoms, respectively.
如果这两个硅原子之间的距离大于形成正常硅氧烷键所需的距离，新形成的硅氧烷键就会存在张力。
The new siloxane linkage can experience strain if the two silicon atoms are not sufficiently close enough for the formation of a normal siloxane linkage.
