coupling medium meaning in Chinese
成对传递体
偶联介质
耦合介质
Examples
- Spurt water column not only is a good coupling medium of ultrasonic , but also can get rid of impurity , such as power , vapor and oil film on the surface of the measured object , so this sensor can adapt various environments
因为水柱不仅是超声波传播的良好介质，还可将被测物表面的粉尘、水汽、油膜等杂质吹走，使系统具有良好的环境适应能力。在恶劣环境下进行位移测量时，该传感器具有其他仪器不可比拟的优越性。 - The difference among the elasticity modulus of various microstructures is probably the main reason , which caused the experiment results above . under the same experiment conditions , such as sample shape , size , surface roughness , establishment of testing system , pressure on the probe , and thickness of coupling medium , the variety of relative attenuation coefficient ( or ) in different heat treatment samples is measured and compared by measuring the attenuation obtained from the cylindrical surface of column . the result is as following : for 40cr and 38crmoal , a mt < az mq < a s < a p + f ; for gcrlssimn , a mt < a annea < s < a p + f ; and a increased with the increasing of frequency
在保证试样形状、尺寸、表面光洁度、系统参数设置、施加在探头上的压力以及耦合层厚度等测试条件一致的情况下，利用棒材圆柱面测衰减系数法，分别测定并比较上述不同热处理试样相对衰减系数的变化情况，得到的实验结果是：对于40cr及38crmoal钢， _ (低温回火) (淬火) _ (高温回火) _ (正火) ；对于gcr15simn钢， _ (低温回火) _ (退火) _ (高温回火) _ (正火) ；且随着频率的提高，衰减系数均呈现增加的趋势。
