Cluster I composed of all materials that came from the USA, Canada, LanZhou and 4 materials that came from Russia.
The materials which had close relationship were located near.
It mainly showed in that the all materials which came from Kazakhstan and the materials which came from the Russia except 3 materials from Sakhalin and 1 material from Samarra were clustered in the same group when the GS was 0.7.
Finally,the materials from the same place had the similar genetypes.
This study showed that there was the abundant genetic background in Phalaris arundinacea Linn materials and there was a further genetic distance between the materials.

In laser cutting of glass with controlled fracture, thermal stress induces a fracture and the
material is cleaved along the cutting path by fracture propagation.
Small tensile stresses on the top and bottom surfaces will make the material separate from up and down to middle, whereas the compressive stresses in the middle ensure stable fracture propagation.
This method usually causes many defects such as chips formation, irregular cut path, micro-cracks and even broken material [1].
Small tensile stresses on the top and bottom surfaces will make the material separate from up and down to middle, whereas the compressive stresses in the middle surface ensure stable fracture propagation [5].

Abstract.
The concept of transformation strain is to be used when elastic medium contains periodically distributed inclusions or micro-mechanical voids in the material.
For experimental research the pulsator with loading capacity of 6000 kN, available at the Institute of Construction and Architecture of Slovak Academy of Sciences in Bratislava, Slovak Republic, was used (Fig. 4).

Introduction
With the progress of science and technology, the continuous development of the cities, the shield construction is widely used in city subway.
The receiving probe will receive the wave reflected, and by recoding the time that the ultrasonic wave propagates in the cutters, the value of the cutters' wear can be calculated easily, the speed of the ultrasonic wave propagates in the material of the cutters can be measured by experiments[3].
