a文献报道CT平扫一般为稍低密度、等密度或稍高密度,并且密度一般较均匀,无钙化或坏死,多为不均匀强化 The literature reported CT sweeps evenly generally for slightly the low density, the equilibrium density or slightly the high density, and the density is generally even, does not have the calcification...
Low Density vs. High Density In the previous examples, the second rock has a lower density even though it weighs more (has a higher mass). This proves why "lighter" and "heavier" should not be used to describe density. Metals typically have densities above 6 or 7 g/cm3because their par...

The temporal evolution of two model high-density/low-density (HDL/LDL) interfaces was examined from molecular dynamics (MD) calculations at temperatures close to the predicted second critical point of water for three water models. In all cases, interfacial density equalisation occurred rapidly showing...
