表示传播疾病或信息的媒介。
Mosquitoes are a vector for malaria.
蚊子是疟疾的传播媒介。
数学和物理中表示带方向的量。

易错句子Vector is a quantity that has both magnitude and direction.
正确表达A vector is a quantity that has both magnitude and direction.
英语可数名词单数用于泛指某一类事物时，前面必须加不定冠词 a/an；汉语没有冠词，'一个'常被省略，所以容易漏掉 a。若要泛指整类，也可以用复数 vectors，但不能单独用单数 vector 泛指。
grammar · medium
易错句子Mosquitoes are vector of malaria.
正确表达Mosquitoes are vectors of malaria.
vector 是可数名词，主语 Mosquitoes 是复数，作表语的名词也必须用复数 vectors 保持数的一致。汉语名词不随数量改变形式（'蚊子是疟疾的媒介'），因此容易漏掉词尾 -s。
grammar · medium
易错句子The mosquito is a vector to spread malaria.
正确表达The mosquito is a vector for spreading malaria.
表示'传播某种病的媒介'时，vector 后接介词 for + 名词或动名词，用来说明所传播的对象；不能用表目的的不定式 to spread。这是把汉语'用来传播……的媒介'逐字译成 to 造成的错误。
单位向量
Divide the vector by its length to get a unit vector.
把该向量除以其长度即可得到单位向量。
向量空间
In linear algebra, we study transformations between vector spaces.
在线性代数中，我们研究向量空间之间的变换。
向量场
A vector field assigns a vector to every point in the plane.
向量场为平面上的每一点都指定一个向量。
病毒载体
The gene therapy uses a viral vector to deliver DNA into cells.
这种基因疗法使用病毒载体把DNA送入细胞。
疾病传播媒介
Ticks are a major disease vector in many rural areas.
在许多农村地区，蜱虫是主要的疾病传播媒介。
