The top of neural tube forms basic encenphalic shape,namely endbrain, interbrain, midbrain and afterbrain. The abnormal closure of neural tube will result in neural tube detects. Encephalocoele is a common congenital malformation whose mechanism was no known. NO participates in the physiologic process of brain.

胚胎脑发育的早期阶段主要是神经板隆起、弯曲、闭合形成神经管，神经管的头部从前向后依次发育形成脑的基本组织形态，即端脑、间脑、中脑、后脑，在神经管闭合过程中出现异常就会导致NTD。

Then the joint capsule, patella, patellar tendon and retinaculum, quadriceps tendon, popliteus tendon, posterior cruciate ligament, menisci, and medial and lateral collateral ligaments were removed, and distal femur, proximal tibia, ACL and its complete attachment points were retained. The specimens were scanned by using a Cyberware 3030 3-D laser scanner to obtain point cloud data.

然后去除关节囊，髌骨、髌腱及支持带，股四头肌腱、腘肌腱、后交叉韧带、半月板、内外侧副韧带等软组织，只保留股骨远端、胫骨近端、ACL及其完整附着点，用Cyberware3030三维激光扫描仪对标本进行扫描，获得点云数据。

The main components were a lateral expansion to the oblique popliteal ligament; a direct arm, which attached to the tibia; and an anterior arm. The oblique popliteal ligament, the largest posterior knee structure, formed a broad fascial sheath over the posterior aspect of the knee and measured 48.0 mm in length and 9.5 mm wide at its medial origin and 16.4 mm wide at its lateral attachment. It had two lateral attachments, one to the meniscofemoral portion of the posterolateral joint capsule and one to the tibia, along the lateral border of the posterior cruciate ligament facet. The semimembranosus also had a distal tibial expansion, which formed a posterior fascial layer over the popliteus muscle.

主要的部分是一个可以侧方扩展的腘斜韧带，最大的膝关节后方的组织结构，形成了一个较大的筋膜外皮位于膝关节的后方，测量结果显示长度为48mm，边缘宽度为9.5mm，侧方附件的宽度为16.4mm，它具有两个方面的附件，一个位于半月板股骨间部分的后外侧关节囊和一个在胫骨端的后叉韧带边缘，半膜肌同时也存在一个远处的胫骨扩展，形成了一个后方的筋膜附着腘肌。

In the theoretical investigation, we calculate the static load-deflection curves and the longitudinal forces transmission for a specified angle difference between the fixed clamp and the moving clamp. To study the stability of the equilibrium configuration, we superpose the equilibrium configuration with a small perturbation and calculate the natural frequencies of the deformed elastica. In addition, the condition where two ends with identical angles are introduced will be researched.
