方法于饮入液体前后通过超声测量54例FD小儿的胃窦容积，得出胃液体半排空时间。
Methods the volume of sinus ventriculi in 54 FD children before and after ingesting a fluid meal was measured by ultrasonography, the half-time of liquid gastric emptying was further calculated.
结果显示脾胃虚弱组胃半排空时间较正常对照组明显缩短（P＜0．01），说明脾胃虚弱者液体胃排空加快；
The results manifested that GET1/2 in'insufficiency of the spleen and stomach group(ISAS)was much shorter than that in the normal group (P< 0.01).
