She graduated in 1986, but remained as a dancer with the Youth Song and Dance Ensemble of the institute. In 1988, she was named as national first class dancer because of her outstanding artistic achievement. At that time she was the youngest dancer to achieve this honor in the Chinese dancing field.展开更多

To do simi-lar material simulation with the minitype and stress-type test device was feasible and high-efficient. Bringing two models with the same geological and mining conditions to bear lateral compressive stress and tensile stress respectively and simulating the process of underground mining, the test results indicate that: under the compressive stress, the col-lapse of the coal roof occurs belatedly and the damaged range in cover of coal seam is smaller, therefore the movement and deformation of the cover and its damage to the ground geological environment are not evident; whereas under tensile stress, the situation is contrary to which mentioned above. A conclusion was obtained from the test that the ground environment hazards in coal mining areas were controlled by the regional geo-logical tectonic stress field.展开更多
