We also observed and measured the distance and section of some muscles such as long muscle of neck、long muscle of head、sternocleidomastoid、trapezius、longissimus、inultifidus、splenius、semispinal muscle of head、semispinal muscle of neck、anterior scalene、middle scalene 、posterior scalene et al. We achieved the moment of force and downloaded the force in the model .We also added gravity of head.

通过横截面积肌力计算法，测量尸体颈椎周围的主要肌肉：胸锁乳突肌、斜方肌、头长肌、颈长肌、肩胛提肌、夹肌、前斜角肌、中斜角肌、后斜角肌、多裂肌等的横截面积及其与颈椎纵轴的中心距数值，求得力矩值，直接或根据力矩等价公式间接的将肌力值加载于模型体表各点。

The horizontal cross sectional area of the connector is larger than that of the hub rod.

连接头的水平横截面面积大于毂柱的水平横截面面积。

Plyfil composite yarns is similar to two-ply yarn structures.

纺纱方法决定着成纱结构，成纱结构与纱线组成原料又决定了纱线的性能。sirofil复合纱线纺纱时长丝与短纤纱须条的间距及长丝的张力，plyfil复合线加工时二组分间并线张力对成纱结构及纱线的性能有着重要影响。sirofil复合纱的成纱横截面呈近似圆形结构，长丝位于成纱的一侧；纵向呈有"股线螺纹"的单纱外观。plyfil复合线具有类似于传统双股线的横截面和纵向外观。

The main work is as followings: First, we use KE SI DA microscope for observing the appearance and configuration of bicomponent fiber. It was found in the bicomponent fiber it is a bilateral array for the PET and PTT. The cross section is anisomerous with PTT and PET side by side. After heat treating the shape of single filament becomes three dimensional curly and the number of crimp is biggest in the condition of relaxation. In the range of some tention, the bulkiness and crimpness fall obviously after the bicomponent fiber is treated with heat.

首先利用科视达观察了PTT/PET双组分复合纤维的外观形态，发现PTT/PET双组分复合纤维中PTT、PET两种组分呈双边分布，横截面呈不对称的哑铃状，PTT和PET两组分分居在横截面两侧，单丝经热处理呈现出三维立体卷曲，在无张力条件下卷曲数最多，在一定的张力范围内，随着所加负荷的增加，PTT/PET双组分复合纤维热处理后的蓬松性及卷曲性均下降显著。

Using image processing technology, we analyze the size and shape of cell wall crystal region of bamboo's cross section during entire growth from bamboo shoot to the mature bamboo. Using region segmentation, we study the forming and distributing characteristic of crystal regions of the fiber cap、 proto-sieve 、 thin-walled cell of vascular bundle of bamboo's cross section.
