序言 在测试超声换能器特性时,如下三点是重要的:①熟悉换能器的工作状态,以便选择最适合各种测试的换能器,②确保换能器发挥出预期的性能,③应很好掌握换能器给超声信号带来的影响。 本文发表的是马萨诸塞州陆军材料技术研究室开发的测试换能器特性的技术及装置。这一测试是由
Preamble The following three points are important when testing ultrasonic transducer characteristics: ① Be familiar with the working state of the transducer to select the transducer that best suits the various tests; ② Ensure that the transducer performs its intended function; and ③ The effect of the transducer on the ultrasound signal should be well understood. This article is published in the Massachusetts Army Materials Technology Laboratory developed test transducer characteristics of the technology and devices. This test is by
