acoustic path meaning in English

声路程
声通路

The paper introduced the theory of passive acoustic localization and the algorithm of space acoustic localization . by use of combined acoustic path difference , the paper amended the passive acoustic localization formula and improved the accuracy of localization
本文介绍了被动声定位的原理及空间声定位的算法，推导出了被动声定位公式，并利用声程差组合改进了被动声定位公式，提高了定位的精度。
Saw excitated by input idt is divided axisymmetrily ( y type ) or centrosymmetrily ( s type ) into two pathes and detected by their output idts . there is a mass loading area located accurately in each acoustic path and fabricated by photolithography technology in y type and s type mass loading sensor devices . as the characteristics of saw sensor are greatly influenced by temperature , these sensors have one acoustic path for reference another acoustic path for measurement in order to reduce the influence of temperature
它们各自具有一个输入idt和两个输出idt 。输入idt激发的saw经过耦合器按轴对称( y型)和中心对称( s型)分成两路，分别由输出idt检测输出。在y型和s型saw质量沉积效应传感器件的传播路径上都有一个由光刻工艺精确定位的质量沉积区。
