The paper designs and makes a kind of active power filter experiment device with four use main circuit and without conformer.

作者设计、制作了一种不用变压器、采用四重化主电路实现的120kVA有源电力滤波器实验装置。

The bias of marginal dose and GTV mould were evaluated by analyzing the process of conforming GTV mould and manual multi-leaf conformer (MLC).

分析手动多叶光栅（MLC）摆位及GTV模具制作过程，计算GTV模具误差及边缘剂量误差。
