各种各样的“口罩”英语[2]

口罩的功效

人们通常从以下几个方面来测试口罩是否好用。

▌Comfort 舒适性

例如：

►These masks are usually very comfortable on the face. But their straps go behind the head and not around the ears, which is less practical for many users. 这些口罩佩戴起来通常很舒服，但是带子是箍在头上，而不是耳戴式，所以对有些人来说不是很好用。

►This mask is usually very comfortable but the plastic edges can leave skin indentations which last longer than other softer masks. 通常来讲，这种口罩佩戴起来很舒适，但是塑料边缘会在皮肤上留下印记，和其他柔软材料的口罩相比，印记消掉要花更长的时间。

▌Air leaking 密封性

例如：

►There is very little leaking if the metal nose bridge is properly pinched together. 如果把金属鼻夹夹紧的话，空气几乎不会漏进来。

►This mask is not quite as snug as some others and I did occasionally smell street odors. 这款口罩不如其他一些口罩那么贴合，我有时候能闻到街道上的气味。

▌Exercising 运动时使用

例如：

►I found it very comfortable to breathe while biking, especially if the model has an exhalation valve. 我觉得戴着这种口罩骑车呼吸十分畅通，尤其是带呼吸阀的那种型号。

►The fabric gets soggy during exercise. I also found it harder to take deeper breaths. 布料会在运动过程中浸湿，而且要深呼吸也很困难。

►I had no problems during biking or jogging with this mask and still felt able to catch a breath. 戴着这款口罩骑自行车或跑步都不成问题，还能喘得上气。

▌Fog factor 眼镜是否起雾

例如：

►I had very little fogging of my glasses with a good seal around the nose. 由于鼻子周围十分密封，所以眼镜上几乎不会起雾。

►Sometimes the nose fit isn’t perfect and my eyeglasses fog up. 有时候鼻子部分不是很贴合，我的眼镜就起雾了。

▌Longevity 使用寿命

例如：

►The mask can last at least a few days of use before losing effectiveness. 这种口罩在持续使用几天后才会失效。

►The mask itself can last for years, and you just pop in a new filter every few days. 口罩本身可以使用多年，你只要隔几天放一个滤芯进去就行了。

有用的句子

最后学一些谈论口罩的有用句子。

►I only strongly recommend truly N95-certified masks such as 3M and Vogmask. 我只强烈推荐真正通过N95认证的口罩，比如3M和Vogmask。

►The only masks that are worth buying are the N95 type. 唯一值得买的口罩就是N95的。

►If you want to protect yourself against the minuscule particles you'll need professional masks. Very pricy and inconvenient to wear. 如果你想抵抗住微颗粒，就必须使用专业面具，很贵，而且佩戴不便。

►After about 2-3 weeks of use, the mask looks horribly grey!! 用了两三周后，口罩都变灰了，可吓人！

►I've noticed that counterfeit/fake masks are a huge problem in China, and I was wondering where will I can purchase authentic 3M masks in Beijing. 我发现中国各种假冒伪劣口罩是个大问题，不知道北京哪里能买到3M正品呢。

►Many masks aren’t good for heavy breathing such as I would do while running. 有些口罩在呼吸沉重的时候，比如跑步的时候，戴着不是很适合。

►The filter life span is said to be 69 hours, so assuming that you bike 1 hour every day, that's 3 month use for one filter - not so bad. 一个滤芯的寿命据说是69个小时，假设你每天骑一小时车，那一片滤芯就可以用3个月，挺不错。

►It sometimes takes a bit of fine tuning the metal nose clip for a good seal.

有时候要稍微调一下鼻夹，才能达到好的密封效果。 ►Air pollution is such a serious issue that we really need to stick with the best masks — with proven results from independent labs, not just TV advertorials and website testimonials. 现在空气污染太严重，我们真的要用最靠谱的口罩才行，得有独立实验室的检验报告，而不是电视广告和网站上贴的各种证书。
