建立了一套高精度的X光导管传输性能测试系统, 对单管和复合管在X光能量为5～30 keV范围内的传输性能进行了系统的实验研究。 结果表明: 单管对低能X光有良好的传输性能, 复合管具有宽波段的传输特性。

A precise system for the measurement of X-ray guiding tubes is established. Systematic experimental study on the transmission characteristics of X-ray monocapillary and polycapillary are performed. The experimental results indicate that monocapillaries have high transmission efficiency for low energy X-ray, and polycapillaries have a wide band transmission property.
