The tensile strength formulas of granular materials are derived under the assumption that granular materials are D-dimension fractal bodies.

假定粒状材料是均匀的D维分形体，由此导出粒状材料的抗张强度公式，并用来估算颗粒在给定压力下的破碎几率。

Using the real-space renormalization group transformation method, critical behavior on two-dimension and d-dimension(d>2) X fractal lattices is studied.

What would happen if the coincidence of Einstein's time progress axis with one spatial dimension of these flat 2-D-spaces around us would get slowly lost?

如果爱因斯坦的时间轴与我们周围的平面二维空间的一个空间维度的恰好慢慢消失的话，会产生什么现象呢？

Soon to come: 4-D, which is 3-D with the added dimension of time -- the same area shot over and over.

Best seen in 3-D, if you can find the right theatre, though the extra dimension continues to seem less of an inspiration than a stunt.

NEWYORKER: Monsters vs. Aliens

As the 3-D fad waned in 1960, producer Michael Todd Jr. tried to take the moviegoer into the fourth dimension.
