Methods: The VX2 tumor cells were planted in the hepatic left-centrallobe of 32 rabbits.
方法：实验兔32只，将VX_2肿瘤细胞植入其肝脏左中央叶制成肝癌模型。

The results show that the increase of duty ratio of output elements will raise the energy of the centrallobe rather than change the centrallobe′s average intensity;
结果表明，输出单元占空比的增加只能提高中心光斑的能量，但无法改变中心光斑的平均光强；

It is concluded that an offset feed parabolic antenna has the advantage in side lobe suppression over central feed parabolic antenna.
