I think' the chests' in you sentence including the jar and other things which is not a any monsters,right?

Yes. Chests=Jars, urns, boxes, crates, chests and such.

Arreat Summit arealevel= 37 ,no drop

The Arreat Summit has no drops because the only monsters there are the Ancients, and they never drop items.

In Nightmare, the area level=the monster level.

some the unque and super unque monsters appear random,but some appear the same area level ,it puzzle me

Uniques are the random monsters. They are monsters with names like Ooze Drool the Hungry or Wind Ripper the Foul. They have random stats, as well, like extra strong and cursed. Super-uniques are monsters like Nihlathak or Corpsefire. They always have the same stats (with boni in nightmare and hell for some) and appear in the same location.
