A static referencemeasurement is taken to avoid the effect of big skin deformation around joints to the measured data of joint markers.
并提出静态参考测量的措施，避免关节周围较大的皮肤变形对测量数据的影响。

The system USES a sophisticated parametric double referencemeasurement technique, that yields precise, highly reproducible results, even with difficult samples.
该系统采用更复杂的参数测量技术，能更精确，高重复性。
