But by the 1770s, whaleships were outfitted with tryworks onboard.

但到了 1770 年代，捕鲸船上就配备了试验装置。

Some of that oil was then used to fuel the tryworks fire itself.

然后，其中一些油被用来为tryworks本身的火灾提供燃料。

They'd go out, kill the whale, chop up the blubber, boil it down in the brick tryworks, and then sail back to Nantucket.

他们会出去杀死鲸鱼，切碎鲸脂，在砖砌工厂中将其煮沸，然后航行回楠塔基特岛。

The key piece of equipment was called a tryworks — it's essentially a big brick furnace where you would render the oil from the blubber of the whale.

关键设备被称为“tryworks”——它本质上是一个大砖炉，可以从鲸脂中提炼出油。

See with what entire freedom the whaleman takes his handful of lamps—often but old bottles and vials, though—to the copper cooler at the tryworks, and replenishes them there, as mugs of ale at a vat.

你看，捕鲸者如何无拘无束地拿着一大把的灯盏——尽管它们往往不过是大大小小的旧瓶子——到炼油间铜制的冷却器那里，把灯装满了油，就像在大酒桶里灌满一杯杯麦芽酒。

Towards the middle of the ship is the tryworks — two big vats, heated by a brick furnace, where the workers would toss in huge chunks of whale blubber to melt down into the valuable oil.

船的中部是试炼车间——两个大桶，用砖炉加热，工人们将大块的鲸脂扔进其中，融化成有价值的石油。
