一、前言十年来微电子学领域的飞速进展革新了科学仪器的设计(Piecce 等1981)。新的设计方法及价廉物美的元件导致具有进行各种复杂操作功能的先进仪器的诞生,特别是微计算机对仪器的控制和数据的分析整理有着巨大的作用。然而,在进行许多耗时和厌倦的纯重复测 I. INTRODUCTION The rapid advances in microelectronics in the last decade have revolutionized the design of scientific instruments (Piecce et al. 1981). New design methods and inexpensive components have led to the birth of sophisticated instruments that perform a variety of complex manipulations, especially the manipulation of instrumentation and the analysis and collation of data by microcomputers. However, many time-consuming and weary tweets are underway
