EG help to promote the formation of carbon layer, while the addition of APP to the combustion of PVA has a certain viscosity, increasing the adhesion of carbon layer.
EG有利于促进炭层的形成，而APP的加入，使PVA在燃烧时具有了一定的粘性，增加炭层的附着力。

The structures of the invention are prepared by adhering a porous dielectric layerto a substantially nonporous capping layer via an intermediate adhesion promoting dielectric layer.
通过将多孔介电层经中间的增粘介电层粘合到基本上无孔的贴面层上来制备本发明的结构。
