摘　　要：为了开展声学系统性能预报技术研究,在对内陆湖的环境边界特性和常年水温剖面统计分析的基础上,根据获取的经验声速计算公式,编制了内陆湖声线轨迹分析软件,利用该声线分析软件提出了一种对声学系统产品性能进行预报和分析的方法,该方法能给出声学系统作用距离预报范围,试验证明该方法可行,最后对预报结果和方法进行了简要讨论。To study the prediction method for acoustic system performance,the surroundings boundary and perennial temperature section characteristic has been analyzed.According to experiential velocity formula,the ray-tracing software for inland lake has been compiled.And a prediction and analysis method for acoustic system performance has been introduced,which based on the software.This method could predict the effect distance for acoustic system.The feasibility of this method has been proved by experiment result.Finally the prediction result and prediction method has been discussed briefly.
