沈阳河面旋转冰圈是怎么形成的 沈阳河面旋转冰圈形成原因

 据媒体报道,1月10日,1月8日,沈阳法库县和平乡的辽河坝水面,形成一个一直在旋转的神秘冰圈,据当地村民介绍,这个旋转的冰圈大小大概可以容纳3辆轿车,并且一直在河面上匀速自转。据了解,这种现象在全球是十分罕见的,一般只会发生在北极、斯堪的纳维亚以及加拿大等高维度地区。

According to media reports, on January 10 and 8, the surface of liaoheba in Heping Township, Faku County, Shenyang, formed a mysterious ice circle that has been rotating all the time. According to local villagers, the rotating ice circle can accommodate about three cars, and has been rotating at a constant speed on the river. It is understood that this phenomenon is very rare in the world, generally only in the Arctic, Scandinavia and Canada and other high-dimensional areas.

这种旋转的冰圈形成原因是因为,在河面的拐角处,加速流动的水会产生一种被称为“旋转剪切”的力量,将冰块切断,然后冰块缓慢旋转。被切断的冰块和周围的冰块相互摩擦,最终形成一个正圆形。 

The reason for this rotating ice circle is that at the corner of the river, the accelerated flow of water produces a force called "rotating shear", which cuts off the ice and then slowly rotates it. The cut ice and the surrounding ice rub against each other to form a positive circle.  

这种情况其实在我国并不是第一次出现了,据报道,辽宁葫芦岛市摄影家陈景朝像往常一样来到位于绥中滨海经济区附近的碣石景点拍摄海上日出,发现海冰面上居然呈现出了无数个大小不一的“冰圈”,有的冰圈还圈圈相连颇为壮观。至于形成,有关专家猜测说,这种漩涡可能是因为海冰封冻后,导致海水内的密度不同,导致了海水流转造成的漩涡,就像将一块砖头丢入水中一样,产生了涟漪。

This is not the first time in China. It is reported that Chen Jingchao, a photographer from Huludao City, Liaoning Province, came to Jieshi scenic spot near Suizhong Binhai Economic Zone as usual to shoot the sunrise on the sea. He found that there are countless "Ice Circles" of different sizes on the sea ice surface, some of which are still connected in spectacular circles. As for the formation, experts speculate that this kind of vortex may be caused by the different density of the sea water after the sea ice is frozen, resulting in the vortex caused by the circulation of the sea water, just like dropping a brick into the water, resulting in ripples.

也有专家表示,这种情况其实是水下的燃气资源影响,导致水中出现旋涡从而使得水面上形成这种旋转的冰圈。

Some experts also say that this situation is actually the impact of underwater gas resources, resulting in vortex in the water, which makes the rotating ice circle on the water surface.
