你能设想一下北家的牌吗?
这两个加倍传达了什么样的含义?

正常情况下感觉是惩罚性加倍。

这是北家的牌,请你结合一楼的叫牌进程进行评价。
第一个加倍(平衡位置的加倍)和第二个加倍的目的是什么?牌力能达到多高?

可能是风格的原因,南家对加倍的应叫不同:实战是1NT.而我用1NT表示8-10P,opp花色有止,建设性的。实际持牌会考虑PASS或1S。
北家的第二次加倍我理解是惩罚性的,实际持牌有风险(若PD的1NT允许很低牌力的话)。
若使用我的风格(1NT表示8-10P),拿北的牌直接3NT。

南家还是叫2D示套吧。这个进程,大家都没叫出高花,面危险花色是C,OPP找到了合适的定约,通知同伴你的1N是基于位置的低限牌力。
