Through constitution of PM space density function, the stress-strain state equation for saturated rocks has been defined and the hysteresis loops of axial stress-radial stress has been simulated.

通过构筑PM空间密度函数，求出饱和岩石的应力—应变状态方程，并模拟了其轴向应变—径向应变滞后回线。

In America, the optimum density for the best use of road space is around 50 vehicles per lane-mile.

在美国，道路最佳使用效率的理想车辆密度大约是每车道英里50辆车。

Europe's higher human-population density leaves less space for energy crops.

欧洲的人口密度更高，所以能源作物的操作空间也较小。

So, the quantum mechanical interpretation is that we can, in fact, have probability density here and probability density there, without having any probability of having the electron in the space between.

量子力学给出的解释是，实际上，我们可以在这有概率密度，在这里有概率密度,但在两个之间没有。

That ideas should freely spread from one to another over the globe, for the moral and mutual instruction of man, and improvement of his condition, seems to have been peculiarly and benevolently designed by nature, when she made them, like fire, expansible over all space, without lessening their density in any point, and like the air in which we breathe, move, and have our physical being, incapable of confinement or exclusive appropriation.

The new LPDDR3, which marks the first time a 2GB LPDDR3 density is available in one space-saving package, utilizes four LPDDR3 chips stacked together.

It's actually a slight step down in terms of pixel density, but the extra space is more than worth it, as now this can make for a passable video player.
