The big cross section of low speed shearing, should satisfy to request system flywheel energy enough, that is to optimize the flywheel structural parameter, and guarantee its step response.

低速大断面剪切时，应满足对系统飞轮能量足够大的要求，即通过优化驱动系统的飞轮结构参数，保证其阶跃激励特性。

The paper firstly put forward the energy indication of geophysical field of gas outburst in accordance with the mechanically destroyed process of gas outburst and the maximum shearing stress theory.

针对瓦斯突出力学破坏过程，采用最大剪切应力理论首次提出了瓦斯突出地球物理场的能量标志。

The results indicated that impact absorbed energy of heat-affected zone in welded joint of X70 pipeline steel were proportional with shearing area on the whole.

结果表明：X70管线钢焊接接头热影响区冲击试样的冲击功与断口剪切面积基本成线性比例关系，冲击功越高，剪切面积越大。

"It takes the same amount of energy to work in a shearing shed for eight hours as it does to run a marathon twice, " said Leann Brimmer, 38, of Biddle, Mont.
