Results There were significant deviation in LESP, LES relaxation rate and the percentageof peristaltic contractions after therapy.
结果：治疗前后L esp, L ES松弛率，蠕动性收缩所占比率均有显著差异。

Compared with other conventional methods, the percentagedeviationof this method is about 1%, so this method can satisfy the demands in related production and work.
用该方法同一些常规方法相比，测量误差在1%左右，能满足有关生产和工作中的使用要求。
