The blocks were the same with the ultrasonic testing of wheelset in rolling stocks, the benchmark for the spot inspection was provided. 該試塊適用於在役輪軸超聲波探傷,為現場檢測提供了統一的探傷基準。
Ultrasonic testing using the through transmission squirter technique remains the predominant method of inspection of composite materials. 超聲波探傷法用的是穿透傳輸噴水技術也是複合材料檢測的主要方法。
