The process was discovered by John Mercer in 1850 when he noticed that cotton undergoes a generalswelling and shrinking when it is treated with caustic soda solution.
该工艺是杰恩·默瑟在1850年发明的,他发现棉经过苛性钠处理后,会有膨胀和收缩现象。

Moreover, the boundary constraint has significant impact on the generalswelling force, and slight increase of expansion strain will cause dramatic decrease of the generalswelling force.
边界约束对于广义膨胀力的影响显著,膨胀应变的略微增加,广义膨胀力大大降低。

The patient developed acute, sudden, severe facial pain and swelling necessitating emergency admission to hospital and operative intervention under general anaesthesia.
