The meridians and parallels of the sphere can be projected on to a plane, by any convenient system . 球面上的子午圈和平行圈可用任一方便的方法投影到平面上。
The study of projections from the cartographical point of view is not here considered as a branch of geodesy . 从制图学的观点来研究投影，不认为是大地测量学的分支。
These sources are generally viewed in projection against radio nebulae representing the remnants of supernova outbursts . 这类源一般都投影在超星爆发残骸的射电星云上。
At any point the convergence is the angle between the meridian as represented on the plane and the n grid line . 一点上的收敛角是子午线在平面上的投影与N坐标线之间的角度。
An image of the patterns on the mask is projected onto the resist-coated wafer, which is many centimeters away . 掩膜板上图形的像被投影到许多厘米以外的涂有抗蚀剂的片子上。
Dehn showed how a presentation of the group of a knot can be read off from a projection of the knot into a plane . Dehn指明了一个纽结的群的一种表示如何由该纽结在平面上的一个投影看出。
A projection is defined as any orderly system whereby the meridians and parallels of the spheroid may be represented on a plane . 投影是一种有规律的方法，用来把椭球面上的子午圈和平行圈映射在一个平面上。
It should be noted that additive production of color is despondent upon the individual projection of each primary onto a common screen . 应该指出，颜色的加色成色作用是以将每种基色分别投影到同一屏幕上为基础的。
Figure 2.1 illustrates the departures of chemical composition from solar values for five different clouds projected against bright stars . 图21揭示出五个不同的投影在亮星背景上的星际云的化学组成对太阳值的偏差。
The multispectral rendition shown in plate vib was generated by projecting records＃1, ＃3, and＃ 4 as blue, red, and green respectively。 图板VIB所示的多光谱再现是将记录1，3，4分别以蓝、红、绿投影而得到的。
