eft_index=True, right_index=True

这是Pandas中merge函数的参数，用于指定合并时使用的列索引。left_index=True会将左边DataFrame的行索引作为合并键，而right_index=True则会将右边DataFrame的行索引作为合并键。如果同时将两个参数都设置为True，则会将两个DataFrame的行索引都作为合并键。

conversion of l eft-handed coordinates to right-handed coordinates

左手坐标系和右手坐标系在空间中的表示方式是不同的。左手坐标系是一种用于描述三维空间中坐标方向的系统，其中正 x 轴指向右侧，正 y 轴指向上方，正 z 轴指向观察者，以观察者为中心。而右手坐标系则使用相反的方向。换句话说，左手坐标系和右手坐标系在 x、y、z 轴的方向上是相反的。

将左手坐标系转换为右手坐标系的方法是将每个轴的方向取反。具体来说，我们可以通过以下步骤完成转换：

1. x 轴的方向保持不变。
2. y 轴的方向取反。
3. z 轴的方向取反。

通过这些步骤，我们可以将左手坐标系转换为右手坐标系。这样，原本左手系中的正方向变为右手系中的正方向，坐标系的表示方式也随之改变。

左手坐标系和右手坐标系在不同的领域中使用。左手坐标系在物理学、计算机图形学等领域中广泛应用，而右手坐标系在数学、工程学等领域中更为常见。因此，在不同的应用场景中，我们可能需要进行坐标系的转换，以适应特定的需求和约定。

总结起来，将左手坐标系转换为右手坐标系的方法是将每个轴的方向取反，具体包括 x 轴方向不变，y 轴方向取反，z 轴方向取反。这样可以使坐标系的表示方式和约定与右手坐标系保持一致。
