In the past, we extensively studied of isotropic materials pressure vessels, but the composite material pressure vessels have a fundamentally difference with them -anisotropy.
过去广泛深入地研究各向同性材料的压力容器，而复合材料压力容器有着与他们本质的不同——各向异性。

When remains the DC power, the decreasing of gas pressure can lead to the increasing of etching rate and the transformation from isotropic etching to anisotropic etching.
在直流功率一定时，工作气压的降低会导致刻蚀速率的增加，并且刻蚀由各向同性转变为各向异性。

The curve shape of pore water pressure developing under isotropic consolidation is not the same as that under anisotropic consolidations.
