本文建立了有血管存在的生物分层组织模型，在此基础上首次分析了血液的存在及流动对测量探头反射系数的影响。
Simulation results show that: a the blood vessels in layered tissues may have a great influence on the reflection coefficient.
应此有人提出了分层介质结构，来研究超声在生物组织中的传输和分布。
So someone purposed layered media structure to study transmission of biologic structure.
研究结果表明：利用GA可有效地反演出生物组织的分层厚度信息和生物组织的某些德拜参数。
Calculation results prove that using GA can well efficaciously reconstruct the information of biological tissues, such as thickness and Debye parameters.
