2023考研英语同源外刊1月文章内容:为何转动时会感到头昏?

Nature abhors change. The principle of inertia, one of the most fundamental laws of physics, holds that objects resist changes in their state of motion: If an object is at rest, it will stay at rest until something forces it to budge, and if it’s moving, it will keep moving until ground to a halt. That’s why spinning makes you dizzy.

大自然有其永恒不变的规律性。惯性力(一个较基本上的物理定律)是物件阻拦运动状态转变的一种特性:假如一个物件是静止不动的,它将维持静止不动,直到外界能量使其健身运动;假如它是健身运动的,那麼它将再次健身运动,直到外力作用使其终止。这就是为何你在转动时会感到头昏。

In the labyrinthine structure of the inner ear, there are three “semicircular canals” arranged at right angles to one another, so that each senses the movement of your head along a different axis, and all three collaborate to orient you in 3D space.

在耳道迷宫般的构造中,有三条彼此之间成斜角排序的“半规管”,每一个“半规管”都能认知你头顶部沿不一样中心线的健身运动,这三个“半规管”会协作给你在三维空间中精准定位。

The canals are filled with a fluid that sloshes around as you move. Your ears sense motion by detecting the way tiny strands of hair lining the canals wave back and forth in this moving liquid, like water plants swaying in a river current.

管路里充满了液态,如果你挪动时,液态会往返摇晃。你的耳朵里面根据检验水渠里细微的体毛在流动性的液态中不停摇摆的方法(如同水草植物在流水中摆动一样)来认知健身运动。

The strands, called hair cells, are suspended in a gelatinous substance called cupula, layered below a fluid called endolymph. When you jerk your head, the endolymph sloshes in one direction or the other through each canal, dragging the slower cupula with it and bending the embedded hair cells to and fro.

这种被称作毛细胞的线状体细胞飘浮在一种称为内耳顶的胶状物化学物质中,坐落于一种称为内淋巴结的液态下边。如果你头顶部猛然一动时,内淋巴结便会从一个方位或另一个方向越过2个半规管,托着速率较快的内耳顶,并使嵌在里面的毛细胞往返弯折。

The information about which way the hair cells are swaying at any given moment gets relayed to the brain via roughly 20,000 nerve fibers, and is interpreted by the brain as movement.

相关毛细胞时时刻刻怎样晃动的消息根据大概2万根交感神经传送到人脑,并被大脑讲解为健身运动。

Now, when you spin in a circle, inertia initially causes the endolymph to slosh in the direction opposite to your head’s motion. It resists the movement of your head, dragging the cupula backwards with it and thus causing the sensory hairs suspended inside the cupula to bend against the direction in which you’re spinning.

如今,如果你在转动时,惯性力最初会造成内淋巴结向与你头部运动反过来的角度晃动。它会抵御你头顶部的健身运动,将内耳顶向后拖动,进而造成悬在强力吸盘内的觉得毛向你转动的方位弯折。

However, within moments, the endolymph (and thus the more gelatinous cupula) adjust to the movement of your head, and start going with the flow. This causes the hair cells to straighten, and your brain no longer receives the message that you’re spinning. Your perception has become normalized to the rotation of your head, giving you the sense that you are still, and the world is rotating around you.

殊不知,不一会儿,内淋巴结(也就是疑胶状的内耳顶)便会融入你头顶部的健身运动,并逐渐随流水而动。这会造成毛细胞拉直,你的人脑不会再接受到你在转动的信息内容。你的直觉早已将你头顶部的转动视作一切正常情况,让你一种你是原地不动的觉得,而全球在你周边转动。

Then, suddenly, you stop! You have halted the rotation of your semicircular canals. But because of inertia, the endolymph keeps spinning, resisting change yet again. As the fluid continues to move, it once again deflects the cupula — this time in the direction in which you were spinning moments before — and as the oozing cupula bends those hair cells, a signal of movement is transmitted to the brain. You sense that you are moving, but you’re not. And that’s dizziness.

随后,你忽然停了出来!你的半规管终止了转动。但因为惯性力,内淋巴结仍在转动,它再度抵抗运动情况的转变。伴随着液态再次流动性,它再度使内耳顶偏移(此次是向着你刚刚转动的方位),当外渗的内耳顶使毛细胞弯折时,健身运动的数据信号就被传输到人脑。你觉得到自身在挪动,但实际上并沒有。同时会造成头昏的觉得。

 

语汇:

abhor [əbˈhɔːr] vt. 厌恶,憎恨

inertia [ɪˈnɜːrʃə] n. 可塑性;惯性力

labyrinthine [ˌlæbəˈrɪnθiːn] adj. 谜宫的;繁杂的

综上所述是得出的-2023考研英语同源外刊1月文章内容:为何转动时会感到头昏?期待对2023研究生考试者们,在英语学科的复习上边有一定的协助!恭祝2023研究生考试成功!
