The demyelination happens in patches along the length of the axon, so it's called segmental demyelination.

因为轴突上只生局限性脱髓鞘，因此又称为节性脱髓鞘。

它鼓只是一额外故事，充满了房间。

The segmental lining ring was considered as a Euler-Bernoulli model, yet the shearing dislocation of segmental ring was excluded.

将节衬环视为 Euler-Bernoulli 模型，但排除了节环剪切位错。

So focal segmental glomerulosclerosis is a type of nephrotic syndrome, that's helpful, but why does the glomerulus develop segmental sclerosis in the first place?

那么局灶节性肾小球肾炎是肾病综合征一种，这很有帮助，但肾小球是如何原性地产生节性硬？

Comparatively, circumferential joints between segmental rings are more pron to dislocation and rotation, resulting in the sharp deformation and steps.

相对而言，节环之间圆周节理更易生位错和旋转，导致剧烈变形和台阶。

Each segmental ring is treated as a Timoshenko beam.

每环被视为一Timoshenko光束。

The flow of the veins are similar to the arteries but in reverse, the only difference is that there's a segmental artery but no segmental vein.

静脉血流和动脉相似，只是血流方向相反，唯一不同是存在肾动脉，但没有肾静脉。

The shield tunnel model comprises segmental rings and circumferential joints between adjacent rings.

盾构隧道模型由节环和相邻环之间环状节点组成。

Each segmental ring is treated as a Timoshenko beam, while the circumferential joints are represented by linear rotational and shearing springs.

每节环都被视为 Timoshenko 梁，而圆周接头则由线性旋转弹簧和剪切弹簧表示。

The segmental ring is simulated by Timoshenko short beam with reduction bending stiffness.

环由 Timoshenko 短梁模拟，降低了弯曲刚度。

Alright so on histology, there'll be segmental sclerosis and hyalinosis of the glomeruli, and under electron microscope, there's effacement of the foot processes of the podocytes.

在组织学上，患者组织活检会出现肾小球节性硬和玻璃样变，在电镜下可见足细胞足突消失。

E denotes Young's modulus of the segmental ring, I is theareamomentofinertiaofthetunnelcross-section, G is the shear modulus, A is the tunnel cross-sectional area.

E 表示节环杨氏模量，I 是隧道横截面惯性面积矩，G 是剪切模量，A 是隧道横截面积。

Segmental means that only a segment, or part of the glomeruli is affected, and focal means that among all those glomeruli in the kidney, only some are affected.

节性，意思是只有肾小球一部受累；局灶性，是指在肾组织所有肾小球中，只有部肾小球受累。

When the tunnel stress field reaches a certain threshold, segmental rupture, leakage, segmental joint opening, and varying degrees of other damage will occur.

当隧道应力场达到一定阈值时，将生节破裂、渗漏、节节理张开等不同程度破坏。

However, increasing the distance between two areas is an effective measure to eliminate the adverse effects on the segmental joint.

然而，增加两区域之间距离是消除对节性关节不利影响有效措施。

Each segmental ring is divided into n1 nodes and 4 virtual displacement nodes are defined at the two ends of the tunnel (Figure 2).

每节环为 n1 节点，并在隧道两端定义 4 虚拟位移节点（图 2）。

Each segmental ring is treated as a Timoshenko beam, and each circumferential joint is considered by two mechanical springs including the shearing spring and the rotation spring.

每节环被视为一 Timoshenko 梁，每圆周节理由两机械弹簧（包括剪切弹簧和旋转弹簧）考虑。

This model incorporates an improved subgrade modulus and treats each segmental ring as a Timoshenko short beam, with each circumferential joint modeled by two mechanical springs.

该模型采用了改进路基模量，并将每节环视为一 Timoshenko 短梁，每圆周接头由两机械弹簧建模。

However, the Timoshenko beam may provide a more accurate representation of the segmental ring to model the ring dislocation, given that the height of the ring is significantly greater than its width.

然而，Timoshenko 梁可以提供更准确环表示来模拟环位错，因为环高度明显大于其宽度。

Alright, so as a quick recap, focal segmental glomerulosclerosis is a nephrotic syndrome characterized by sclerosis and hyalinosis in some, but not all, glomeruli, and usually only affects part of the glomeruli that it affects.

得！快速回顾一下：局灶节性肾小球肾炎是一种肾病综合征，以部肾小球硬和玻璃样变为特征，通常只影响肾小球一小部。
