Hence, the loss of gravitational potential energy of the block equals the gain of elastic potential energy of the spring . 因此,该物块的重力势能的减少,等于该弹簧的弹性势能的增加。
Isothermal elastic potential 等温弹性势
The research results indicated that it is the protection against outburst mechanism of the measure that elastic potential of coal is slowly released , zone of stress concentration is moved forward , length of stress relief zone is increased and the quantity of gas emission is reduced after injecting water 研究结果表明:该措施的防突机理在于注水后,煤体弹性潜能释放缓慢,集中应力带前移,卸压带加长,瓦斯涌出量减小。
