There is obvious difference in absolute speed and angle of projection between male long jumpers in our country and abroad.

我国男子跳远运动员在绝对速度和腾起角度上与国外优秀选手存在明显差距。

With respect to the third angle projection, this paper sets forth briefly its rationale, characteristics, and chart reading, in the form of comparison.

本文用对比形式扼要地阐述了第三角投影法的基本原理、特点和看图方法。
