上一次定位 meaning in Chinese

last fix

The characteristic of all of world coordinate system is , coordinate of every time fixed position and locate coordinate does not have a relation last time , the coordinate location system that touching screen is an independence on physics , the data that feels every time passes the coordinate that calibration turns to go up for screen , such , no matter be below what circumstance , with respect to requirement feeling screen this covers coordinate , bit samer output data is stable , if be not stabilized , so this feeling screen locates with respect to unwarrantable absolutely coordinate
绝对坐标系统的特点是，每一次定位坐标与上一次定位坐标没有关系，触摸屏在物理上是一套独立的坐标定位系统，每次触摸的数据通过校准转为屏幕上的坐标，这样，就要求触摸屏这套坐标不管在什么情况下，同一点的输出数据是稳定的，假如不稳定，那么这触摸屏就不能保证绝对坐标定位。
