- The growth of grains is affected by crystallographic aeolotropy.
- To solve the aeolotropy between wells and formations through melt-shield and block-shield way.
- The invention improves the design for aeolotropy oil reservoir water drive effect in the filed of oil exploration.
- The diamond crystal assumes disorderly arrangement, isotropism in PDC，and overcomes the defects such as monocrystal volume too small, aeolotropy and so on.
- Through the study of mechanical experiment, the uniaxial compression strength indices and shear strength parameters are put forward, which indicate that several typical soft rocks have strong aeolotropy, and that strength parameters are all very low.
