【摘要】 针对现阶段吸声设计中存在的工作量大效率低的问题,利用MS的Access数据库及SQL语言设计了声学数据库系统。该数据库不仅能够实现吸声材料和吸声结构的简单查询和多条件查询,而且还能够通过计算比较自动选择最佳的吸声结构及材料,并且还具有可扩展及易维护等特点。更多还原

【Abstract】 In view of the problem in sound absorption design,an acoustic database has been designed with ACCESS and SQL in this paper.With many restrictions,the database has the basic functions that to supply the inquirement of the material and sound absorption structure that we wanted,moreover,the most practical material and the best sound absorption structure can be obtained automatically with its.help.Furthermore,the system is extensible and robust.更多还原
