以霞石正长岩取代长石，按照浮法玻璃的成份制备配合料并熔制玻璃。

Using nepheline syenite as a substitute for feldspar, the batch mixtures were prepared on a composition of float glass and are melted into glasses.

长石溶蚀产生的次生孔隙对于该区天然气储集空间的贡献很大，经统计分析可知在流纹质熔结凝灰岩和流纹质凝灰岩中的长石溶孔分别占孔隙度的18.61％和13.71％。

For example, in Xujiaweizi area, pores as a result of feldspar corrosion in rhyolitic ignimbrite and rhyolitic tuff make up of 18.61% and 13.71% respectively of the all the porosity.
