It also expounds such ar projectivemethods and properties for points various spherical curves and sphere systematically.
然后,系统地阐明了点、各种球面曲线以及球面的园弧投影方法和性质。

By using the role and the drafting methods, projective contour line of a quadric at random position can be drawn.
利用这一规律和作图方法,可以解决任意位置的非退变二阶曲面的投影轮廓线的作图问题。

The related researches developed the indirect methods that effectively capture and study the implicit stereotype such as judgment latency measures and projective measures and so on.
