一、引言各种类型的离子敏感场效应晶体管(i.s.f.e.t.s)的发展目前正取得如此大的进展,因此,研究常用的离子选择薄膜电极之类的新器件、新装置是有用的。因为pH玻璃薄膜电极是最普遍使用的类型,而且在理论和实践中最易理解,所以本文把这种电极的概念用作说明常用薄膜电极的范例。为了明瞭起见,记住以下界面现象的定义是十分重要的: I. INTRODUCTION The development of various types of ion-sensitive field-effect transistors (i.s.f.e.t.s) is currently making so much progress that it is useful to study new devices and devices such as the commonly used ion-selective membrane electrodes. Because pH glass film electrodes are the most commonly used type and are best understood in theory and practice, the concept of such electrodes is used herein as an example to illustrate commonly used thin-film electrodes. For the sake of clarity, it is important to remember the following definitions of interface phenomena:
