Aiming at forecasting the torpedo acoustic homing range for actual targets under real water conditions, this paper summarizes the typical water conditions in different sea spaces and seasons, presents a forecast method of torpedo acoustic homing range, and establishes a transmission loss forecast model based on the ray acoustic theory and a reverberation level forecast model based on the cell scattering model.

针对真实水文条件下鱼雷声自导对实际目标的作用距离预报问题，总结了不同海域、不同季节的典型水文条件，提出了鱼雷声自导作用距离预报方法，以射线声学理论为基础建立了传播损失预报模型，以单元散射模型为基础建立了混响级预报模型。

Reverberation is dependent only on the volume of a space and the acoustically absorptive quality of the rooms finishes.

混响是依赖于空间体积只有一个房间的装饰和声学吸收品质的影响。

Results Compared with conventional ultrasound,sonoCT could suppress the reverberation artifacts in bile duct and gallbladder obviously.Lateral boundaries and adumbration of the carcinomas were improved,resolution of internal structure echos also enhanced.

结果 与传统声像图比较，胆管、胆囊腔内混响伪像明显减弱，提高了肿瘤轮廓的清晰度，增强了病灶内部结构与回声的分辨率，增加了超声诊断胆道肿瘤的可信度。

Lateral boundaries and adumbration of the carcinomas were improved,resolution of internal structure echos also enhanced.Thus,sonoCT raises the reliability of biliary tract tumors diagnosed by ultrasound.

结果 与传统声像图比较，胆管、胆囊腔内混响伪像明显减弱，提高了肿瘤轮廓的清晰度，增强了病灶内部结构与回声的分辨率，增加了超声诊断胆道肿瘤的可信度。

Chamber - An elongated ambient space such as a hall, stairwell or elevator shaft creates this reverb type.

商会 -一个细长的环境空间，如大厅，楼梯或电梯井创造了这个混响类型。

The observation data are collected from some specific experiments in the laboratory cistern, the lake and the ocean.

混响数据是在专门设计的水池实验、湖上试验和海上试验中现场采集的。

The original method to confirm reverberation time in designs is to use computational formula W .

最初在设计中确定混响时间的方法是利用W·C·赛宾在本世纪初提出的计算公式。
