接触地

There is little connective in the peripheryof the pancreas islet,so endocrine portion contacts suff...

胰岛外周仅有极少量的结缔组织，致使内、外分泌得以充分密切地接触。

From this point simply swing forward and up and the racquet will naturally become vertical at contact, provided that you swing from the shoulders and do not get too wristy.

从这点，假定网拍在接触点下面一呎，只是前和上挥拍, 如此网拍将自然地在接触中变垂直，假设你是从肩膀挥拍而且不是太用到手腕的话。
