纵波位移是极向量，在坐标系由右手坐标系变成左手坐标系（或相反）时，不改变位移方向；

P-wave displacement is a polar vector, and its direction remains unchanged when we move it from right hand coordinate system to left hand coordinate system(or in the opposite way).

虽然左手系和右手系都是很常用的系统，但是也有很多其他种类的坐标系用于3-D软件。

Although left-handed and right-handed coordinates are the most common systems, there is a variety of other coordinate systems used in 3-D software.
