超短脉冲激光照射固体靶时可将其能量在极短的时间内沉积在靶表面一个极小的空间范围内，在固体靶表面产生固体密度的等离子体。
Differing from the long pulse laser the ultra short laser will deposit its energy on the surface of the solid target in very short time and produce solid dense plasmas.
而年龄、手术切除范围、照射部位、剂量、手术与放疗间隔时间等与预后均无明显关系。
There was no close relationship between survival and other factors, such as age, extent of surgery, initial site, irradiation dose, or the interval between surgery and radiotherapy.
