摘要：
A method capable of forming a sufficiently thick low alkali concentration region without heating glass to a high temperature and even in an atmosphere which is not an atmosphere of plasma formation gas such as helium and argon, is provided. A glass substrate having a pair of main surfaces and being made of glass containing an alkali oxide in its composition, is disposed between a first electrode and a second electrode so that one main surface is separated from the first electrode and the other main surface is brought into contact with the second electrode, and a corona discharge is generated by applying a direct-current voltage to the first electrode as a positive electrode and the second electrode as a negative electrode, in a positive-electrode-side surface layer portion of the glass substrate, at least one positive ion including an alkali ion migrate toward the negative-electrode-side.
摘要（中）：
提供了能够在不将玻璃加热到高温的情况下甚至在不是诸如氦和氩等离子体形成气体的气氛的气氛中形成足够厚的低碱浓度区域的方法。 具有一对主表面并由其组成中含有碱金属氧化物的玻璃制成的玻璃基板设置在第一电极和第二电极之间，使得一个主表面与第一电极分离，并且另一个主表面被带入 与第二电极接触，并且通过在玻璃的正极侧表面层部分中施加作为正极的第一电极和作为负极的第二电极的直流电压来产生电晕放电 衬底，包含碱离子的至少一个正离子向负极侧迁移。
