The viruses that have an envelope are called enveloped viruses.

有囊膜的病毒称为囊膜病毒。

West Nile virus is also an " enveloped virus" because the capsid is covered by a lipid membrane.

该病毒还是有包囊的病毒，因为衣壳外有一层脂质层。

But Bibby said enveloped viruses usually don’t fair too well when exposed to liquids. Take the AIDS virus.

但毕比说包膜病毒通常在遇到液体后存活得不好，以艾滋病为例。

There are two types of herpes simplex viruses —HSV1 and HSV2 —both of which are part of a larger family of enveloped double-stranded DNA viruses: the herpesviridae family.

单纯疱疹病毒有两种血清型：HSV-1和HSV-2，两者都归属于一类更大的、有包膜的双链DNA病毒家族：疱疹病毒家族。

It dies very, very quickly. And HIV is an enveloped virus and I think that this is probably one of the lines of evidence that's been used, ”said Bibby.

很快就死亡了。而且艾滋病毒是一种包膜病毒，我想可能这就是该规定的理论依据。”
