The free edge of the tentorium is in close contact with the brainstem, which is the region that connects the brain and the spinal cord.

小脑幕的游离缘与脑干紧密接触；脑干是连接大脑和脊髓的区域。

The free edge of the falx cerebri is in close contact with the central part of the brain, called corpus callosum, which connects the left and right hemisphere.

大脑镰的游离边缘与大脑的中央部分密切接触，即胼胝体，连接左右脑半球。

The second type of supratentorial herniation is central herniation, and that's when the diencephalon and parts of the temporal lobes slip under the free edge of the tentorium.

第二种幕上脑疝叫做中央疝，即间脑和部分颞叶被推入小脑幕游离下缘。

In this herniation, the innermost part of the frontal lobe, called the cingulate gyrus, gets squeezed below the free edge of the falx cerebri to the opposite side of the skull.

在这种脑疝中，额叶最内侧的扣带回被挤压推入大脑镰的游离缘下，进入对侧颅腔内。

Now the uncus isn't only directly compressing the right side of the brainstem, but indirectly, it's also pushing the left side of the brainstem against the free edge of the tentorium forming what's called a Kernohan's notch.

这时钩回不止会直接压迫脑干右侧，同样也会间接压迫脑干的左侧部位，将其推向小脑幕的游离缘，形成Kernohan切迹。

But when a liquid can't form a perfect sphere because it's not in space, like when it's resting on a surface or filling a container, its free edge will curve as much as possible to approach that spherical state.

但是当液体因为不在空间中而不能形成完美的球体时，比如当它停留在一个表面上或填充一个容器时，它的自由边缘会尽可能地弯曲以接近球形状态。
