求翻译：弹性模量，弹性是指受外力作用后的变形，在外力去除后的恢复能力，而抵抗变形的能力，通常被称作刚性，其量化指标用模量，即材料单位应变所需应力的大小来表示。底板 floor模量大，整体抗变形能力强，击球时力量集中，方向准确，击球反弹力强而速度快。是什么意思？

Elastic modulus, elastic deformation by external force, the ability to recover after the removal of the external force, and the ability to resist deformation, usually referred to as rigid, quantitative indicators of the modulus, the material required for agencies to adapt to stress size to be said.
