1) measuring attenuator
测量衰减器
2) compensating attenuation meter
衰减补偿测量器
3) attenuation measurement
衰减测量
1.
The attenuation measurement range is limited by the two facts of non-linearity at high signal level and ratio of signal to noise at low signal level.
限制衰减测量量程的因素是大信号测量的非线性以及小信号测量的信噪比,采用射频部分替代法能够在加大信号功率提高信噪比的同时而不引入大信号测量的非线性,是扩展衰减量程的有效方法。
4) attenuation method
衰减法测量
1.
With the measured X-ray energy spectra of a 6 MV medical linear accelerator produced by Beijing Medical Equipment Institute by the attenuation method and analysis decomposition algorism- the PDD- OAR curves of the accelerator were calculated- which were compared with directly measured data of PDD- OAR curves for same accelerator.
从比较的结果看,无论能谱测量、MonteCarlo模拟结果,还是通过PDD和OAR曲线的测量和计算,都证明把衰减法测量的X射线能谱作为对未知头部结构的加速器进行放疗计划验证的技术路线是可行的。
6) attenuation gauge
