英文稿件：报道韩国岁月号客轮沉没事件

The South Korean Sewol ferry, a passenger ferry, sank off the coast of Jindo Island on April 16, 2014 at 8:58 a.m. in Jindo-gun, South Korea. There were 476 passengers onboard when the ship set sail from the port city of Incheon, including mostly high school students on a school trip, and a few other passengers. Sewol's capital and crew fled the sinking ship early on rather than helping passengers. Officials said there were only 179 survivors rescued before the ferry capsized and sank.

韩国轮船沉没事件2017真相

超载时船仍漂浮，浮力等于重力，所以浮力变大；

高速航行的客轮在突然转向时货物由于具有惯性而发生侧移；

客轮沉没过程中，浮力小于重力，由于深度增加，根据p=ρ 水 gh，受到海水的压强将变大．

故答案为：变大；惯性；小于；变大．
