The other day I talked about longitude and latitude which are measured as angles around the equator and toward the poles.
我之前谈过经度(longitude)和纬度(latitude),它们是用来标度连接两极的经线、以及平行于赤道的纬线的角度单位。
The angles refer to the polar view angle, i. e. the angle measured from the vertical.
角涉及到极面观的角,例如垂直物上测量的角。
The azimuth Angle change between the two units can be calculated by once operation according to the deviation angles and relative torsion angles measured with the units at each point.
在一次测量过程中,两组测量单元可以测出各自所在位置的井斜角和相对扭转角,由此可计算出两个单元之间的方位角变化。
