很急~~~~請幫我翻譯以下英文文章

這是一篇英文期刊

我已經用翻譯機翻出大概ㄉ意思ㄌ

請幫我翻ㄉ順一些

畢業報告要用ㄉ

感激不盡!!!

nano materiaLs Provide Broad-spectrum Sun Protection

UltravioLet Radiation and the Skin

Ultraviolet radiation (UVR) from sunlight is only about 5% of the total amount of electromagnetic radiation reaching the Earth's surface; however, it has been shown to be very harmful to the skin. Electromagnetic radiation is classified according to wavelength (1nm =10-9 m), and shorter wavelengths have higher frequencies and higher energy.

The dimensions of the relevant UV wavelengths begin at 290 nm and extend;through 400 nm (Figure 2) and are classified as UVE (290-320 nm) and UVA (320-400 nm).

Most of the UV radiation reaching the earth is surface is UVA.Radiation between 400 -700 nm is classfiend as visible (light), and above 700 nm is infrared heat). Radiation below 290 nm is UVC and is highIy damaging.However UVC is screened out by the ozone layer of the atmosphere and does not reach the earth's surface.

Excess exposure to both UVA and UVB radiation are known to be risk factors for skin cancer as well,so the need for broad-spectrum filters for skin protection clearly has been established. Titanium dioxide (TiO) and zinc oxide (ZnO) long have been recognized as efficient particulate agents that filter UVA and UVB from solar radiation

    UltravioLet Radiation and the Skin

    紫外線輻射及皮膚

    Ultraviolet radiation (UVR) from sunlight is only about 5% of the total amount of electromagnetic radiation reaching the Earth's surface;

    在陽光中存在的紫外線輻射 其實才佔到達地球表面的電磁波的百分之五

    however, it has been shown to be very harmful to the skin. Electromagnetic radiation is classified according to wavelength (1nm =10-9 m), and shorter wavelengths have higher frequencies and higher energy.

    但是紫外線輻射已經展示出其對皮膚非常有害 電磁波是用波長來歸類 短一點的磁波有比較高的頻率及能量

    The dimensions of the relevant UV wavelengths begin at 290 nm and extend;through 400 nm (Figure 2) and are classified as UVE (290-320 nm) and UVA (320-400 nm).

    紫外線的磁波波長長度從290nm 到400 nm 並歸類成兩種 分別是UVE (290-320 nm) and UVA (320-400 nm).

    Most of the UV radiation reaching the earth is surface is UVA.Radiation between 400 -700 nm is classfiend as visible (light), and above 700 nm is infrared heat).

    大部份的UV輻射線到達地球表面是UVA . 輻射波介於400到700nm被歸納成看的見的光線 , 高於700nm則為紅外線熱

    Radiation below 290 nm is UVC and is highIy damaging.

    輻射波低於290nm 的是UVC 極具傷害性的

    However UVC is screened out by the ozone layer of the atmosphere and does not reach the earth's surface. 不過UVC 會被大氣層的臭氧層給篩選調所以不會到達地球表面

    excess exposure to both UVA and UVB radiation are known to be risk factors for skin cancer as well,

    在UVA 及UVB電磁波下大量的曝曬已知是造成皮膚癌的危險因子

    so the need for broad-spectrum filters for skin protection clearly has been established.

    所以對於能夠保護皮膚的多用途的濾器已經有所需求

    Titanium dioxide (TiO) and zinc oxide (ZnO) long have been recognized as efficient particulate agents that filter UVA and UVB from solar radiation

    TiO 和Zno很久就被認可為有效可以過濾從太陽輻射線來的UVA和UVB的微粒

    nano 材料提供寬廣光譜太陽保護

    紫外線輻射和皮膚

    紫外線輻射(UVR) 從陽光是只大約5% 總額電磁輻射到達地球的表面; 但是, 它證明是非常有害的對皮膚。電磁輻射被分類根據波長(1nm = 10-9 m), 和更短的波長有更高的頻率和高能。

    相關的紫外波長的維度開始在290 毫微米和extend;through 400 毫微米(圖2) 和被分類作為UVE (290-320

    毫微米) 並且UVA (320-400 毫微米) 。

    大多數紫外輻射到達地球是表面的是UVA.Radiation

    在400 -700 毫微米之間是classfiend 作為可看見(光), 並且在700 之上毫微米是紅外熱) 。輻射在290 毫微米以下是UVC 和是highIy damaging.However UVC 由大氣的臭氧層篩選, 不到達地球的表面。

    對UVA 和UVB 輻射的剩餘暴露為人所知是風險因素為皮膚癌, 因此對寬廣光譜過濾器的需要為皮膚保護清楚地建立了。二氧化鈦(TiO) 並且氧化鋅(ZnO) 長期被認可了作為高效率的屬於顆粒的代理過濾器UVA 和UVB 從太陽輻射
