求翻译：结果表明，样品在溅射功率为8W，压强为4.7Pa，氩气流量为30sccm，清洗时间为48min的条件下，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 showed that the samples in the sputtering power 8w, pressure 4.7pa argon flow 30sccm, cleaning time 48min conditions, the sample surface clean and free of damage, the luminous intensity and cleaning compared to 61.34%.

Results indicated that the samples in sputtering power, pressure is 8 to 4.7 W Pa, argon gas flow of 30 SCCM, the cleaning time for 48 min under the conditions of the sample surface clean and free of damage, the intensity before cleaning with over 61.34 % .

The result indicated that, the sample in the sputtering power is 8W, the intensity of pressure is 4.7Pa, the argon current capacity is 30sccm, the clean time is under the 48min condition, the sample surface does not have the damage cleanly, before its luminous intensity and the clean compared enhanc

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