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。

The results indicate that the saturant crosslinking density, the lowest degree of swelling of the PEO R-150 water-swollen hydrogel films produce an unfavorable effect on their machinery strength.

这表明PEO R - 150溶胀水凝胶膜饱和的交联密度和过低的平衡水含量对其机械强度产生了不利的作用。

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。

a perfectly spherical shell dr at some distance, thickness, d r, dr we talk about it as 4 pi r squared d r, so we just multiply that by the probability density.

在某个地方的完美球型壳层,厚度，我们把它叫做4πr平方，我们仅仅是把它,乘以概率密度。
