This combination of flexion of the neck and extension of the head improves the alignment of the axes of the oral cavity, pharynx, and larynx, facilitating optimal visualization of the vocal cords.

颈部屈曲、头部过伸使口腔、咽部、喉部成一直线，使声带充分暴露。

The initial range-of-motion exercises are performed to prevent adhesion formation; extension is allowed to 0°, but it is essential to avoid both hyperextension and flexion past 90°, which can place undue tension on the grafts.

最初的关节活动范围练习主要是为了防止粘连形成，伸展的范围可达0°，但必须避免过伸以及屈曲超过90°，否则可能会使移植的肌腱承受过度的张力。

When the Hamiltonian system is introduced into the research of dynamic buckling in cylindrical shells, the problem uses dual variables in Symplectic space instead of variables in traditional Euclidean space. The symplectic eigenfunction expansion method gives out an exact solution space. So many problems are solved, which can not find the solution in traditional methods.

将哈密顿体系引入结构的动态屈曲研究中，其意义在于将结构的动态屈曲研究从传统的欧几里得几何空间进入到由原变量和对偶变量组成的辛几何空间之中，从而使辛本征函数展开的直接解析法得以实施，这样就可以求解许多以往半逆凑合法无法求解的问题，并且所得到的解空间是完备的。

Uncomfortable symptoms including dizziness, dim eyesight, cardiopalmus, acratia will appear when seated for a long time because of cerebral blood flow reduced for the reason of cervical vessels flexure or compressed, which result in lack of oxygen and nutritive materials.

由于久坐头处于前屈位，颈部血管轻度屈曲或受压，会使流向脑部的血流受到限制，脑血流量减少，从而造成大脑的氧和营养物质供应不足，出现头晕、眼花、心悸、乏力、手足麻木等不适症状。

Knee arthroplasties are designed to accommodate flexion, axial rotation and anteroposterior translation.

设计人工膝关节假体要使其能够具有屈曲、轴移和前后平移功能。

随着手指出的手套，中间关节处取出就与手指sleeves.matched与手套，手掌自由移动，使各宽容的行动（例如fisting ， grabing ，拥抱好，领会好，拥抱，屈曲，捻线，捕捉，同时考虑等），武术可以做的，由球员。

A further redistribution of crimp, tending towards an equalization of warp and weft crimps, will occur when the cloth is allowed to relax off the loom.

在织物下机并充分松弛后，纱线的屈曲会进一步调整，使经纱、纬纱的屈曲趋于相同。

Result: The joint gap of flexion and extension both increased after resecting PCL.

结果：后交叉韧带切除后可以使屈曲时内侧间隙增加5.12±1.48mm，外侧间隙增加4.91±0.95mm。
