perpendicular line

We made two slits for the eyes and a perpendicular line for the nose

我们划了两道缝儿做眼睛，另外划了一条竖线做鼻子。

Methods: The perpendicular line to the plane of cavilla was selected as the base line to make a 5 mm of thick MRI scan in 30 cadaver heads.

方法：选取30例成年人正常头颅标本，以过蝶平面延线的垂线为基线行5mm层厚MRI扫描，开颅取脑、染色、制作相应切片。

Method Fifty cases of Colles fracture combined with DRS, 100 cases of simple Colles fracture without DRS, and 100 normal wrist joint controls were included. We analysed central point displacement and perpendicular line ratio on the lateral view X ray.
