您要查找的是不是：
- A vertical or nearly vertical line or plane. 垂直线，垂直面垂直或近似垂直的线或平面
- At right angles to a vertical line. 横的与垂直线成90度角的
- Please notice, it is a vertical line. 请注意,这是一条垂直线。
- A vertical line dividing a staff into equal measures. 小节线把五线谱分成相等节拍的竖线
- When a user selects an object, a vertical line extends from the center of the object to the grid. 当用户选择一个对象后，从对象的中心有一条垂直线扩展到网格。
- Note: When valve is installed above a horizontal line or on a vertical line, on steam service, equalizer pipe must have a water seal loop. 注：如果在蒸汽应用场合，阀门安装在水平管道的上方或在垂直管道上，则必须配置平衡管以形成水密封回路。
- A vertical line drawn from the pinbone to the ground should drop through the nails of the rear foot. 从髋骨至地面而下的垂直线应该穿过足后的指甲落下。
- The change of a vertical line segment to a curve with negative slope indicates the change from postdepositional to syndepositional faulting. 简单后沉积型正断层的断距不随地层年龄的变化而变化，其断距纵剖面图为一垂直线段。
- The grand staff is formed by the joining of two staves by a vertical line, brace or bracket at the left, to form one system. 大谱表由左端用垂直线与花括号连接起来的两个五线谱组成。
- At the upper left, the end of the drifting plume is punctuated by Alnitak, Alnilam, and Mintaka in a vertical line, the belt stars of Orion. 左上角的漂移尾气被垂直排列成一条直线的参宿一，参宿二和参宿三截断，这就是猎户座的腰带星。
- Step 6: From this point draw a vertical line down to the horizontal axis. This will be the minimum flow capabilitiesof the valve based on these variables. 步骤6:从这一点划垂线向下与横轴相交。这就是以这些变量为基础的阀门的最小流量能力。
- The vertical line meets the horizontal one here. 垂直线与水平线在此相交。
- Its characteristics include that the counter force is proportional with the horizontal distance of a vertical line where BHA is offset from an open hole. 新的纠斜控制方法以减小测量点与开孔点垂线间的水平距离为目标,可以提高垂钻轨迹的垂直精度。
- Two types of symmetry are most often employed in interfaces: vertical axial symmetry (symmetry along a vertical line, usually drawn down the middle of a group of elements) or diagonal axial symmetry (symmetry along a diagonal line). 界面中常用到两种对称，即垂直轴对称（沿一根垂直线对称，此线常位于一组元素的中央）或对角线对称（沿对角线对称）。
- A vertical section of fabric; a gore. 编织品的垂直部分; 三角形布
- In the transformation of descriptive geometry, no matter the method of change plane or revolve, the oblique line can be changed to a vertical line in two successive transformations. 在画法几何投影变换中,不论用换面法或旋转法,一般位置直线均需两次变换才能变成投影面垂直线。
- In this paper,radiative heat transfer method is applied to study the distribution of net heat flux of a combustible surface on a horizontal plane and a vertical line in a compartment fire. 本文用辐射换热的方法研究了可燃物在室内火灾环境下的表面热流密度随位置变化的分布,以及加入其它可燃物后所带来的变化。
- Before disassembling the strut assembly, draw a vertical line with a marker across each component. This will help you reinstall all the OE parts with the original factory orientation. 拆卸避震之前，在各部件连接的位置画上垂直的线，帮助你在重新安装零件时候保持原厂的角度。
- In a vertical or perpendicular line. 垂直地在一条垂直线或竖直线上
- to project a vertical line from point A upward to B 从A点向上画一条线到B
