重金求小论文英文摘要

通过接触角测量、扫描电子显微镜(SEM)和全反射傅里叶红外光谱(ATR-FTIR)等手段研究了功率密度对水接触角、表面能、表面粗糙度、表面化学成分及老化效应的影响。结果表明，功率密度对均匀DBD材料表面改性有重要影响。当处理时间一定时，功率密度越大，接触角下降的越多，表面能上升的越快。增大DBD处理的功率密度，利用更少的处理时间就能得到同样的处理效果。表面样貌及化学成分分析表明，在相同的处理时间下，功率密度越大，薄膜表面粗糙度越大，表面引入的含氧基团也越多。采用大功率密度充分处理后，表面的老化效应相对缓慢，能更好地保持处理效果。 专业词汇翻译不准没关系，要语句结构。 |

| By means of contact angle measurement, scanning electron microscopy (SEM) and total reflection Fourier transform infrared spectroscopy (ATR-FTIR), the effect of power density was studied on the contact angle of water, surface energy, surface roughness, surface chemical composition and aging effect. The results showed that DBD power density has a major impact on the homogeneous surface modification of materials. When fixed the processing time, greater power density is, smaller the contact angle is, and more rapidly the surface rised. When power density of DBD was increased, for less treating time we will get the same effect. Through analyzing morphology and composition of the surface appearance, it showed that greater power density is, more rough the film surface is and more oxygen-containing groups are. also introduced more. Employing high power density, the aging effect of the surface is relatively slow, which could maintain the treatment effect better. |

相信我的翻译能让您满意。呵呵。 The effects of watt density on the contact angle of water, surface energy, roughness of surface, chemical composition and aging effect of surface were studied by measuring the contact angle and scanning electron microscopy (SEM) and total reflection Fourier transform infrared spectroscopy (ATR-FTIR). The results showed that watt density significant effect on surface modification of the homogeneous DBD materials. The contact angle declined and the surface energy raised fast with the augmentation of watt density Within a specific processing time. However, the same effect would yield in shorter processing time once the watt density of DBD treatment aggrandized. The results of Surface appearance and chemical composition analysis showed that the greater watt density is, the more rough the film surface is and more oxygen-containing groups are introduced to surface. And the aging effect of the surface is weaken treated with adequate high watt density, thus can maintain the effect of the treatment better. |

| Through the contact Angle measurement, scanning electron microscope (SEM) and total Fourier infrared spectroscopy (atr-ftir) means of water and power density is studied and surface contact Angle and the surface roughness, surface chemical composition and the effect of aging. Results show that the power density on the uniform DBD material surface modification has important influence. When processing time, power density, the contact Angle, the decline of the surface can rise faster. Increasing the power density, DBD processing using less processing time can get the same treatment effect. Surface appearance and chemical composition analysis shows that, at the same time, power density, the film surface roughness, introduced the oxygen molecules. Using high density fully processed, the relatively slow aging surface, can better maintain treatment effect. |

凑合着看看吧，做了一定程度的修改 The effects of watt density on the contact angle of water, surface energy, roughness of surface, chemical composition and aging effect of surface were studied by using contact angle instrument, scanning electron microscopy (SEM) and total reflection Fourier transform infrared spectroscopy (ATR-FTIR). The results showed that watt density played a significant role on surface modification of the homogeneous DBD materials. Within a specific processing time, the contact angle declined and the surface energy raised fast with the augmentation of watt density. However, the same results could be achieved in shorter processing time once the watt density of DBD treatment aggrandized. The results of Surface appearance and chemical composition analysis showed that the greater watt density was, the rougher the film surface is and more oxygen groups are contained. With manipulated by adequate high watt density, the aging effect of the surface is relatively slow, which can maintain the effect of the treatment better. |
