我打赌你不知道!我们这么约定:你来开我超载的船。如果它沉了,我会得到大额的保险赔偿。如果你拒绝开船,我就把你扔进监狱。怎么样,听起来很不公平吧?在1 870年,船主们就是这么要求他们的船员的。在密度大,含盐量很高的水里,开船一般没问题,可是到了温暖的,密度比较小(温度越高,水的密度越小——译者注)的水里,船就会越沉越低,直到完全沉没。1876年,在一个名叫塞缪(miu)尔·普利姆索尔的政治家的支持下,一条法律通过了。这条法律要求船主在船身上画一条吃水“安全线”——一旦水没过了这条安全线,行船就不安全了。直到今天,这条“普利姆索尔线”还被广泛应用着。
I bet you do not know! We are so agreed: You to open my overloaded boat. If it sinks, I will get a large amount of insurance compensation. If you refuse to sail, I’ll throw you in prison. How does it sound unfair? In 1870, the shipowners demanded their crew. In dense, salty waters, there is generally no problem with sailing, but when it comes to warm, less dense waters (the higher the temperature, the lower the water density) Lower and lower, until completely submerged. In 1876 a law passed with the support of a politician named Miu del Poulsol. This law requires the owner to draw a draft “safe line” on the hull - it is unsafe for the boat to pass once the water has passed. Until today, this “Plimsoll Line” has also been widely used.
