In this study, the East Asians were the ones who focused on the centre but Blais suggests that this could be because they were homing in on the area that gives them the best overall view of the entire face, namely the centre.

在这项研究里，亚洲人只专注在脸部的中心位置，但Blais解释说：这可能是因为他们在这个中心位置可以整体地看到人脸，因此才叫中心位置。

The crus breve incudis is an important marker for operation. The anatomical position of PE is constant. The depth of PTC affects the procedure for cochlear implant surgery via mastoid process-facial recess approach. The location of vestibular window and the round window is relatively stable, so the stapes head can be used as a reference for drilling scala tympani.

通过将位置设定为两个制动位置之一，就可以知道电动机的启动位置。

The forward kinematics is analyzed by choosing one of the mechanisms which have one, two,three or zero angle constraint.Wherein,3-CCC is a new parallel mechanism which has three angle constraints and three distance constraints, Calay\'s formular and direction cosine matrix are used to describe the rotation matrix respectively.By setting Dixon\'s and Sylvester\'s resultant with the three angle constraint equations respectively and using parameters replacement to deal with the distance constraint equations,the 64 order input-output equation of the forward kinematics is obtained under both of the methods.Numerical example confirms these theretical results and the motion simulation is shown in VC++ by integrating OpenGL.

3对高小山提出的广义并联机构进行了研究，以其中具有角度约束的并联机构进行了分析，选取具有一个、两个、三个和零个角度约束类型中各一个机构进行了运动学正解求解，其中3-CCC是一种全部由圆柱副构成的具有三个线线角度和三个距离约束的新型并联机构，文中分别用Calay公式和方向余弦两种旋转矩阵建模方法对其位置正解进行了分析，通过对三个角度约束方程分别构造Dixon结式和Sylvester结式，以及对三个距离约束方程进行变量代换分别导出了位置正解输入输(来源：4040ABC论文网www.abclunwen.com)出方程，得出64组位置正解，并使用数值算例验证了其全部根。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
