相交的两直线构成空间夹角，该角的投影角将随两直线的位置状态不同而改变。

The two intersected lines form a space Angle. The projective Angle of which will change with the change of the location of the two lines.

同时巡线系统不断地检测机器人当前的位置状态，将此刻位置状态与理论正确状态相比较、判断。

Besides, the line-tracking system constantly detects the current location state of the robot. It compares the current position with the correct condition in theory and then the judgement is made.

没有，在没有进行任何构成测试障碍区状况或改善球的位置状态行为的前提下，他不受处罚——见规则13 - 4的例外1。

No, provided nothing is done which constitutes testing the condition of the hazard or improves the lie of the ball - see Exception 1 to Rule 13-4.

So if you start and end at the same place, they've got end at the same place that they started.

所以如果你开始和结束于同一个位置，它们最终的状态与开始时会是一样的。
