This is a normal vector of the same length as n, well, up to sign.
这是与N长度相同的法向量，只是符号不定。
So if you have some region of space S and you call its boundary surface S and you let n be the normal vector that goes out of the region R.
如果存在一些区域空间,边界为曲面,定义n为指向区域R外的法向量。
It is showed from vector analysis: N, P and K are deficient in poplar unfertilized and they are limiting factors to poplar.
矢量法营养诊断结果表明：未施肥的杨树各组织N、P、K均为缺乏状态，N、P、K是杨树生长的限制性因素。
