ρ是密度，对吗？
So these two together, l times rho, give us mass per unit area.
这两个量，l乘以ρ,一起给出单位面积上的质量。
The total mass is the volume, which is the area times the length times rho.
总质量是体积，也就是面积乘以长度乘以密度。
OK, so if I have a point here, then rho will be the distance from the origin.
这里有个点，ρ表示它到原点的距离。
We tend to use the Greek letter rho, If you were to use Excel, it would be correl or sometimes I say corr.
我们习惯用希腊字母rho表示，如果你使用Excel，会用correl表示，有时我也用corr。
The other way to think about it is at this point, 1 well, rho is equal to one because you are on the sphere.
另外一种想法是从这个点出发，因为在球面上，所以ρ是。

Melanin transfer is also accomplished by the interactions of lectins and glycoproteins, by the action of E-cadherin, SNAREs, Rab and Rho GTPases.
黑素细胞的胞吐作用和角化上皮细胞的吞噬作用是黑素传递的最可能的机制。
Extron 1-5 of RHO gene was amplified by polymerase chain reaction (PCR), and the mutation of RHO gene was screened by direct DNA sequence measurement.
采用聚合酶链反应(PCR)方法扩增rho基因第1 ~ 5外显子和第1内含子基因片段，用直接dna测序法筛查rho基因突变。
But, basically you don't really need to remember these formulas as long as you remember how to express r in terms of rho sine phi, and x equals r cos theta.
事实上你不用记住这些公式,只需要知道r=ρ*sinφ,而x=r*cosθ
Starting on the left, look for the Lagoon and Trifid nebulae, the Cat's Paw, the Pipe dark nebula, and the colorful clouds of Rho Ophiuchi and Antares (right).
