  1. Method for measurement of ultrasonic attenuation coefficient of solid by pulse echo technique

    用脈沖回波技術測量固體超聲波衰減系數的檢測方法
  2. This method overcomes the difficult and unrealizable experiment conditions that are used to measure the absolute attenuation coefficient and impels the technique of ultrasonic characterization to be more closed to the engineering requirements and more practical

    該方法克服了絕對衰減系數測定法對實驗條件要求極為苛刻、難以實現的不足，使得超聲表徵技術更接近工程條件、更具實用價值。
  3. Standard test method for measurement of ultrasonic attenuation coefficients of advanced ceramics by pulse - echo contact technique

    用脈沖反射接觸技術測量高級陶瓷超聲衰減系數的標準試驗方法
  4. In addition, concrete inner defects are identified based on two different physical parameter, velocity and attenuation, which will greatly increase precision and reliability. in conclusion, the developed ct technique of ultrasonic for concrete non - destructive test is of great significance in both theory and practice

    在利用速度反演得到混凝土聲速和衰減反演得到混凝土吸收系數的基礎上，本文根據聲速和衰減兩種不同的物理參量判別混凝土內部缺陷，可大大提高缺陷判別的精度和可靠度。
