雄性尾羽的长度两倍于体长并以“叉向抹刀状”告终。
The male's tail feathers are twice the length of its body and end in disc-shaped 'spatules'.
这个尖叉的四个尖角紧贴着这下颚和胸骨，而其长度设计的仅够受害者轻微的张嘴招供。
The four sharp points snugly nestled under the chin and sternum were designed to allow the victim just enough range of motion with his mouth to murmer a confession.
用一个二叉搜索树或者将串切分成长度的平方根那么长的小段都可以解决这个问题。
Using a binary search tree or dividing the string into segments as long as the square root of the length of the string will solve the problem.
建立高度平衡的二叉搜索树是为了提高二叉搜索树的效率，减少树的平均搜索长度。
The highly balanced binary search tree is established in order to improve efficiency of the binary search tree and to shorten the average search tree.
使用测量显微镜对石英音叉驱动叉指的长度和宽度在主要工艺过程中的变化进行了测量，其中以石英音叉化学腐蚀引入的尺寸误差较大。
The lengths and the widths of driving forks are measured with measuring microscopes in the main machining processes. The chemical etching of quartz is the main reason of machining errors.
