各种各样的“口罩”英语

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。

►Many masks aren’t good for heavy breathing such as I would do while running.

►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.
