Examples of Cevians are medians, angle bisectors and altitudes.

Cevians的例子有三角形的中线，三角形的角平分线和三角形的高线。

Furthermore, reactors and warp-nacelles (either single-midline or twin-outboard or both) could be arranged in various ways and replaced as more advanced components became available. USRSC was presumably not referring to quality-control problems when it proudly proclaimed in 2150 that no two Bisons were identical.

此外，曲速吊舱（可以以一具安排在中线或两具在船舷，或着三座一并安装）能以多种形式安排，或者按需求以更先进的组件替换亦可。2150年，USRSC骄傲的宣称没有2艘野牛是完全一样的。

Clinical data and Methods: Laparoscopic left colectomies carried out in the Department of General Surgery, Nanfang Hospital from 2003 to 2004, on 15 left colonic cancer patients were observed and analyzed on the anatomical natures of fascias posterolateral, middle to the left colon, posterolateral to the rectum, as well as the laparoscopic location markers.

临床资料和方法：2003~2004年南方医院普通外科施行的腹腔镜左半结肠切除术15例，病例均为左半结肠癌。对腹腔镜下左半结肠后外侧、中线侧和直肠后外侧相关筋膜的解剖特点和镜下定位标志进行观察和描述。

According to the literature about the manufacture models of three kinds,radial feed- rolling cutter ,broach and Gleason cutter,the effect of centre point-centre line method,centre deviation method and oblique feed on qualified gear length were inspected.

根据滚刀、拉刀及格利森铣刀盘三类径向进给的制造模型相关文献，考察了中点中线法、中心偏移法、斜向进给对给出合格齿长的影响，指出了各类刀具的制造模型的异同，为这种研究提供了借鉴

The penile mass was located just proximal to the glans penis and measured 3 x 4 x 3 cm. Sonography revealed the mass to be located in the midline, displacing both corpora cavernosa laterally. It was well encapsulated, showing a uniform echo texture, isoechoic to the corpus cavernosum, with no involvement of Buck's fascia.

阴茎的肿块就位于龟头的近端，大小为3×4×3cm，超声显示肿块位于中线处，将两侧海绵体挤向侧方，其包膜清晰，回声均质，与海绵体呈等回声，未累及Buck筋膜。
