| 摘 要： | 国外进口的模拟超声仪器多为增益型。汕头超声仪器研究所生产的ECHOPE-220、230即是增益型出口产品,国内也有许多用户使用这种仪器。直接用此仪器制定和使用曲线很不习惯。当把这类仪器衰减器读数盘的数字进行相应的修改后,即可做为衰减型仪器来使用了。

| Abstract: | Most analog ultrasonic flaw detectors importing from foreign country are gain model.ECHOPE-220 and 230 ultrasonic instruments producing by ShanTou city ultrasonic instructions institute is gain model.Most customers in our country used the instruments.They are not customary to set down and use curve by using the instruments indirectly.When we modified relative reading panel of attenuator of these instructions,we can use the instruments as attenuation model. |
