摘　　要：现代大型建筑中一般采用中央空调对建筑室内温度进行控制,其系统的设计一方面要考虑建筑物的实际情况合理选择系统结构,同时又要合理对监控点位进行选择,从而减少能耗,减少监控系统的投资,获得最大的收益。本文针对大型建筑物中央空调监控系统中结构选择和监控点设计这两个主要影响因素进行了一定的分析。In computer simulation of elastic waves,the accuracy and efficiency depend on the method used for calculating the spatial derivatives in the wave equation and on the method for the time integration.Errors in the numerical calculation are mainly from the approximation of spatial derivatives.This paper presents a new algorithm for the calculation of spatial derivatives.It enables us to extend simulations to shorter wavelengths.An example of reverse-time migration of a synthetic data set showed that the numerical dispersion could be significantly reduced with respect to schemes that are based on finite differences.

关 键 词：中央空调监控系统 集散控制系统 监控点位
