紫外線：紫外線 (UV: Ultraviolet)

UV is an abbreviation of Ultraviolet. In RO water purifiers, the bacteria or germs which are present in the water cannot get killed by reverse osmosis process but this process can banish the dissolved solids and ions. These types of bacteria and germs can be killed by the UV rays. Therefore, in almost all of the RO water purifiers, the water is made to proceed through the UV radiation source tube. It reveals the water to UV radiation that destroys the injurious bacteria and germs.

UV是紫外線的縮寫 。 在RO凈水器中 ， 水中存在的細菌或細菌無法通過反滲透過程殺死，但是該過程可以清除溶解的固體和離子。 這些類型的細菌和細菌可以被紫外線殺死。 因此，在幾乎所有的RO凈水器中，使水流過UV輻射源管。 它向紫外線揭示了水，這些水可以消滅有害的細菌和細菌。

紫外線的優點 (Advantages of UV)

• The human body requires UV from the Sun to produce vitamin D. Vitamin D aids make stronger bones, muscles and immune system of the body.

  人體需要來自太陽的紫外線才能產生維生素D。維生素D助劑可使骨骼，肌肉和免疫系統更強壯。

• The cure for skin conditions is done by using UV such as psoriasis. The shedding of cells too rapidly and the development of itchy and scaly patches by the skin occur in this condition. The expansion of the skin cells slows down and relieves the symptoms due to revelation to UV.

  通過使用紫外線(如牛皮癬)來治愈皮膚疾病。 在這種情況下，細胞脫落得太快，皮膚發癢和鱗片化。 由于暴露于紫外線，皮膚細胞的擴張減慢并緩解癥狀。

• To produce certain chemicals called 'tryptamines', the sunlight stimulates the pineal gland in the brain suggested by the research. Enhancement of a person's mood is happened by these chemicals.

  為了產生某些稱為“色胺”的化學物質，陽光刺激了研究表明的大腦中的松果體。 這些化學物質會增強人的情緒。

• To trace many ripe fruits, flowers, and seeds that emerge out more strongly from the background, few animals comprising birds, bees and reptiles are capable of to observe into the near UV light.

  為了追蹤從背景中更加強烈地出現的許多成熟水果，花朵和種子，很少有包括鳥類，蜜蜂和爬行動物在內的動物能夠觀察到近紫外光。

• As a reference for navigation in flight, lots of insects use UV emissions from celestial objects. This is the reason; a light at times attracts flying insects by making troublesome in their navigation process.

  作為飛行中的參考，許多昆蟲都利用天體的紫外線輻射。 這就是原因； 一盞燈有時會使飛行過程中的麻煩事吸引飛行中的昆蟲。

紫外線的缺點 (Disadvantages of UV)

• UV is an ecological human carcinogen. It's the most significant and widespread cancer-causing agent in our surroundings.

  紫外線是一種生態人類致癌物。 它是我們周圍環境中最重要，最廣泛的致癌劑。

• When skin cells are damaged then there is a burn occurs which is called Sunburn. The absorption of energy from UV rays is caused by damage to the skin.

  當皮膚細胞受損時，會發生灼傷，稱為曬傷。 紫外線對能量的吸收是由于皮膚受損引起的。

• On the immune system, over-exposure to UV radiation has a detrimental suppressing outcome.

  在免疫系統上，過度暴露于紫外線輻射會產生有害的抑制結果。

• Damaging of the tissues of eyes occurs due to extended revelation to UV or high intensities of UV and can become a reason for a 'burning' of the eye surface, which is called as 'snow blindness' or photokeratitis.

  眼睛組織的損壞是由于長時間暴露在紫外線下或紫外線強度高而引起的，并且可能成為眼睛表面“灼傷”的原因，這被稱為“雪盲”或光性角膜炎。

• UV destroys the collagen and connective tissue under the top layer of the skin which speeds up the aging of the skin.

  紫外線會破壞皮膚頂層下的膠原蛋白和結締組織，從而加速皮膚老化。

• Lots of polymers used in consumer items comprising plastics, nylon, and polystyrene are wrecked down or be unable to find strength due to revelation to UV light.

  消費品中使用的許多聚合物，包括塑料，尼龍和聚苯乙烯，由于暴露在紫外線下而被破壞或無法找到強度。
