1. Meanwhile the dislocation itself moves further on along a glide plane . 2. Therefore each material has its own characteristic Burgers vectors for each glide plane . 3. It uses two-seater sailplanes, LET L-23 Super Blanik and other LET Gliding Planes . 4. In a wider sense, an improper rotation may be defined as any "'glide plane . 5. The isometry group generated by just a glide plane operation is an infinite cyclic group. 6. Optical observation under a microscope showed that these were accurately perpendicular to the glide planes . 7. The latter is often called the diamond glide plane as it features in the diamond structure. 8. An " e " plane is a double glide plane , one having glides in two different directions. 9. The orientation of the differential stress then determines which glide planes are active and which are not. 10. However, a glide plane operation with a nonzero translation vector in the plane cannot be reduced like that.
