中文摘要：

提供了一种用于设计医用电子直线加速器（1inac）X射线均整过滤器的方法，并将其用于电子束辐射系统的优化过程之中。采用MonteCarlo模拟计算方法，提供了2个真实的国产医用电子直线加速器的辐射研究成果：BJ-20加速器的15MVX射线辐射系统和BJ-14加速器的12MeV电子柬辐射系统。使用传统方法对上述成果进行了验证。

英文摘要：

A method for designing an X-ray flatness filter for medical electron linac is developed. It is used in the optimization process in the electron beam radiation system. Monte Carlo simulation method is used and two examples of real radiation system optimization processes for China-made medical electron linac are provided： 15 MV X- ray system of BJ-20 linac, and 12 MeV electron system of BJ-14. Results are verified by using the traditional method.
