AIM: to observe the distribution and expression of two subtypes of very low density lipoprotein receptor (VLDL r) in diabetic adipose tissues to investigate their changes and significance.

目的：观察极低密度脂蛋白受体(VLDL - R)的两种亚型在糖尿病患者脂肪组织中的分布和表达，以探讨其变化及意义。

We also obtain the variation of the radial dispersion of velocities with r through the stability of the density wave in three-dimensional dishlike galaxies.

同时，从三维盘状星系密度波的稳定性讨论推出了径向速度弥散度的变化规律。

And when we define that as r being equal to zero, essentially we're multiplying the probability density by zero.

当我们定义ｒ等于０处，事实上是把概率密度乘以０．

And one common way to think about it, is to think about the value of r, or the radius, below which 90% of that electron density is going to be contained.

而通常的想法，是想象，r，的值，也就是半径的值，即有百分之九十的电子密度,都落在这个范围之内。
