positional precision meaning in Chinese

位置精度位置精度

But it is gas medium with compressibility and low viscosity that leads to low natural frequency , small damping ratio , low positional precision and rigidity , bad low speed characteristics , which limit the application of pneumatic servo technique
但因为气体的可压缩性和低粘性,导致气压伺服系统固有频率低、阻尼比小、定位精度和定位刚度低、低速性能差,使得气压伺服技术的应用受到限制。
