租约

When does the lease of the house run out?

这房子约何时到期?

He signed the lease yesterday.

昨天他在约上签了字。

The court held that Congress had intended vested rights under the lease to be invulnerable to defeasance by subsequently issued regulations.

法院认为，国会在立法时意，约赋予权利不能因其后颁布条例作废。

What this shows is that the purpose of the provision of timely redelivery in the charterparty is to enable the ship to be at the full disposal of the owners from the redelivery date.

这说明约中订立及时还船条使船舶自还船日起完全处于船东处置之下。
