This article introduces the characteristics and application of warp-knitted geotextiles that lacework, reversibles, biaxial and multiaxial compound fabric.
The conoscopic interference patterns of crystals are calculated for any orientation biaxial crystal, which include information of isochromatic curve and isogyre.
Increasing biaxiality of molecular shape, the system will form a para-biaxial nematic phase at higher temperature.Decreasing temperature, the system will continuously enter into normal biaxial phase.
