§1.引言 现代电气、化工、生物工程和航天飞行器、航空飞行器、核反应工程等都是复杂的系统工程.在这类工程的科学研究和工程设计中,经常需要用常微分方程组的初值问题来建立系统运动行为的数学模型.为了获得研究和设计的数据。
Abstract In this paper the relationship between discontinuities for the solution ofordinary differential equations and that for condition functions are discussed. Theconception and method of extension processing for discontinuities are presented. It isproved that the zero of a condition function with extension processing is the zeroof the condition function, which is a discontinuity point. The algorithms of proces-sing discontinuities are constructed, and numerical experiments show that the algorit-hms are efficient.
