An abdominal ultrasound may be used to check for the presence of pancreatitis, a pancreatic abscess, a pancreatic tumor, or free fluid within the abdominal cavity. 腹部的超声检查可以发现胰腺炎,胰腺脓肿,胰腺肿瘤或者腹腔内存在液体。
Showed free fluid area and stiff intestine. 2例见腹腔游离液暗区,并有肠管僵硬、蠕动差。
To analyze the effect of air on the propagation characteristics of elastic wave in dry soil, based on Biot's theory, the plane wave solutions in porous two-phase medium were derived and the velocity formulations for free fluid and no fluid situations were obtained. 为分析气体对干土中弹性波传播特性的影响,基于Biot理论推导了两相介质平面波动解,以及孔隙流体自由流动和孔隙无渗流两种极限情况下的波速公式。
In the upper layer of the membrane, the free fluid space is introduced and described by the Navier-Stokes equations. 针对错流超滤的特点,在膜的上层部分引入了流体自由流动空间,用Navier-Stokes方程来描述。
Nuclear magnetic logging is a high technology and only by which the free fluid porosity of an oil-bearing bed can be measured directly. 核磁测井是当代唯一能够直接测量油层自由流体(FF)孔隙度的高技术。
