SP is a portable, strongly-typed, event-oriented, discrete system simulation language, It is derived from PASCAL by adding some simulation functions.

SP语言是可移植、强类型、面向事件的离散系统模拟语言，是以PASCAL语言为基础进行模拟功能扩充而形成的。

Difierent from event oriented logic simulation system widely being used, we present a new design method-wave form and some relative algorithms, which are thoroughly process-oriented.

异于目前广泛采用的面向事件的模拟系统，本文提出了基于面向过程的波形字逻辑模拟系统的结构、设计和实现方法，并给出了系统中使用的主要算法。

Therefore, people concern more and more on how to build the distributed event-handling oriented log system.

因此，人们开始关注如何建立面向事件处理的分布式日志系统。
