求翻译：结果表明，当溅射功率为8W，压强为4.7Pa，氩气流量为30sccm，清洗时间为48min时，样品表面清洁无损伤，其发光强度与清洗前相比提高了61.34%。是什么意思？

The results show that when the sputtering power, 8w,, pressure 4.7pa argon flow 30sccm, cleaning time is 48min, the sample surface clean and free of damage, luminous intensity and cleaning compared to 61.34%.

Results indicate that, when splash W, power is 8 to 4.7 Pa pressure argon gas flow rate, for 30 SCCM to 48, the cleaning time when min, samples, and cleaning the surface without damaging the intensity before cleaning with over 61.34 % .

The result indicated, when the sputtering power is 8W, when the intensity of pressure is 4.7Pa, the argon current capacity is 30sccm, the clean time is 48min, the sample surface does not have the damage cleanly, before its luminous intensity and the clean compared enhanced 61.34%.

Results show that when the sputtering power 8W, pressure 4.7Pa, argon gas volume is 30sccm, the cleaning time is 48min, the sample surface clean and no injuries, 61.34% increase in its intensity as compared with before cleaning.
