Home position shear tests of slope rock, point loading tests and indoor AMD simulation action tests in XingQiao concave slope had show shearing strength and coherence between body layers of quartz sandstone decrease by 13.2%~21.3% after attacked by AMD, the angle of internal friction between layers is decreased by 5.0%~7.5%, in general, AMD affects the rocks mechanical property at range of 60~100m interior the perpendicular slop. Data analysis shows: 1 The actions to slope are major focused on zone of weakness, shearing strength of slope foot and AMD centre are reduced by 52% and 64.7% separately. 2 The explosion stress wave of long distance field has obviously increasing influence to disturbance amplitude value of slope with increasing of the slope height and distance, the response of the top of slope and fault region are obvious as well as damage effect; the foot of slope is with smallest disturbance amplitude value, the disturbance amplitude value of the step close to free face is obviously bigger than the interior of slope. 3 With the coupling effect of the AMD and explosion loading, the stress distribution inside of slope mainly presents characters of explosion stress field; the area affected by AMD becomes a weak area of shearing stress.

Results show that after CO2 increases double, the area of forest and rare tree steppe of grassland area in the North of China will increase, the area of the rest will decrease, and the distribution pale of most grassland vegetation have the trendency of moving westwardly and northwardly;moveover besides the area with very drought climate, the grassland production of most areas will increase at different extent, thereinto, the area of Qing—Zang have over 20% increase, the north area of Xinjiang have 10%—15% increase, the grassland production in NeiMongol have less than 5% increase.
结果表明,CO_2倍增后,中国北方草原区森林和稀树草原的面积增加,其余各类草地面积都有所减少,且大多数草地植被的分布界线都有西推北移的趋势;而除气候极干旱地区外,绝大部分地区草地生产力都有不同幅度的增加,其中青藏区增加幅度超过20%,新疆北部增加幅度在10%~15%之间,内蒙古自治区草地的生产力增加幅度不到5%。

If they did move, and saved the penalty, the referee could insist on the penalty being retaken. In a Scottish 1945 game between Kilmarnock and Partick Thistle, Tommy White had to take a penalty seven times!
如果移动了,而且救出了点球,之前的点球可以视为无效,并重新再罚一次点球。1945年在 Kilmarnock 对阵Partick Thistle 的苏格兰联盟杯比赛中,判给其队的一次任意球,Tommy White却踢了7次。
