The purpose of this study is to explain 'Nexus' which is Jespersen's important grammatical concept and to help promote a better comprehension of the English structure on the part of its learners. The term 'Nexus' may be defined as a construction, between a subject and a predicative, or between a subject part and a predication. By introducing the grammatical concept of Nexus, Jespersen attempts to account for the generative processes of sentence construction and to point out the difference between the 'notional' (underlying) structure and the grammatical (surface) structure of a sentence. For example, Jespersen (l924:122, 1969:42) claims that the underlying relation between the cage and empty in the sentence I found the cage empty is the nexus the cage was empty, and thus the sentence should be analyzed S V 0 (S₂P). The complement the cage empty in the structure I found the cage empty consists of a subject, a verb, and a predicative as the equivalent of a sentence the cage was empty. The complement also has the implicit underlying structure which has a subject as a primary and predicative as a secondary. The term 'junction' is a combination of wards which represents a joining of two elements or a joining of more than two elements. A junction is distinguished in three 'ranks'. In a junction terribly cold weather, terribly is a 'tertiary' as its function to restrict the secondary cold, and cold is a 'secondary' as its function to specity the 'primary' weather. Therefore, in a junction the secondary elements (adjuncts) are joined to a primary word as labels or distinguishing mark. Jespersen (l958:97) maintains that as regards terminology the terms 'primary', 'secondary', and 'tertiary' are applicable to nexus as well as to junction. It is also useful to use the special terms 'adjunct' for a secondary word in a junction, and 'adnex' for a secondary word in a nexus. For tertiary we may use the term 'subjunct'. The difference between nexus and junction can be shown by way of comparison : a nexus is like a drama in which we get life and movement, while a junction is like a solid state of a brick wall. The dog furiously barks. (Nexus) The furiously barking do. (Junction) The concept of nexus seems to explain grammar more easily than any other approach. That is the reason why I have strongly been encouraged to study it.

지난 10여년간의 연소분야에 대한 연구는 크게 세가지 방향에서 괄목할 만한 발전을 이루어 왔다. 그 첫째는 대용량 컴퓨터의 개발에 따른 수치해석능력의 신장을 들 수 있고, 둘째는 실 험에서 레이저를 이용한 비접촉 계측방법의 발달을 들 수 있다. 또한 이론적 관점에서는 1974 년이래 유체역학에서 프란틀의 경계층 이론에 비견될 수 있는 접합점근방법(matched asymptotic technique)를 이용하여 예혼합 화염의 전파속도, 확산화염의 구조 및 점화/소화현상, 열폭발문제, 화염의 안정성 등에 관한 엄격한 해석이 가능하게 되었다. 이로서, 종래의 현상적, 물리적 설 명으로 이해될 수 없었던 분야를 해석할 수 있었다. 이에 따라 본 강좌에서는 연소분야의 이 론적 연구에 초점을 맞추어 접합점근방법의 기초개념 및 해석방법을 소개하고자 한다. 이를 위해 2장에서 확산 화염과 예혼합 화염의 특성을 설명하고, 3장에서 화염면 극한의 해석, 4장에서 확산 화염의 구조해석을 통한 점화/소화현상 및 5장에서 예혼합 화염에의 응용 등을 소개한다.
