The existence of anisotropy in paramagnetic cubic crystal s has never been observed and it was only vaguely conjectured by Schlapp and Penney in 1932 for chrome alums.

立方顺磁晶体的各向异性从未有实验观察的报道，仅Schlapp和Penney(1932)在理论上对铬矾作过含混的臆测。

Most coal beds have massive cracks and cleavages, and when seismic wave propagating in them, seismic wave will exhibit anisotropy.

大部分煤层存在着大量的裂隙和节理，地震波在其中传播时具有各向异性。

Goat condyles of the mandible are a type of anisotropic and linearly elastic material.

山羊的髁突是各向异性的线弹性体，其弹性参量与下颌骨相应参量间有差异。

And then, nine elastic coefficients and all of the technical constants of orthotropic condyles were calculated.

But the study of non-well-distributed substance of differency in nature in every direction has been ignored in the approximate solution of Voigt and Reuss, and as a result, it is not a overall conclusion.

针对各向异性非均匀体，采用变分法及能量极值原理进行分析，得出了一个比Voight -Reuss和Hashin -Shtrikman上、下限近似解更为精确和合理的上、下限计算公式

G. it is up to 80 eV when the cluster plane is parallel to the surface. In addition, the impact induced adsorption of C〓 cages was studied in detail. After impacting, the normal incident C〓 was found to move laterally on the surface due to the anisotropic interaction between the dimerized surface and the cage. Finally, it resided on the top of a dimmer or in the trough, which are the energy favored adsorption sites.

在能量为10-20eV的C〓富勒烯表面吸附动力学过程的研究中，我们还发现表面结构的不对称性会引起团簇-表面相互作用的各向异性，从而导致入射团簇在表面上有与入射方向垂直的的横向运动，最后吸附在两个二聚体的中心点和谷点，这两个位置是能量最低的的吸附组态。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
