The zone between the region contacted with bottom of the mould and the freeforming region shows stretch forming and then transferred to plane strain state.
模底接触区与自由变形区交界处的大塑性变形区依次处于板料曲面内双向伸长变形和平面应变状态；

It found that with the same load amplitude and different loading times, several different deformation modes exist no matter for freeforming or for modeled forming.
发现在载荷幅值相同、加载时间不同时，无论是自由成型还是有模成型，都存在着几种不同的变形模式。

High levels of GABA can prevent neurons forming new connections - and slow down the brain's ability to learn - while low levels free nerve cells to create new brain circuitry.
