Although there is usually low signal on both sequences due to a paucity of protons, high signal can be explained by a surface relaxation effect by the calcium salt particle precipitated in the brain.
虽然由于缺少质子,两个序列都显示为低信号。高信号可以用钙盐颗粒沉积于脑内所致的表面弛豫效应来解释。
Current drilling technology requests that polyanionic cellulose (PAC) has better properties to tolerate salt, calcium, high temperature, and enhance mud viscosity remarkably.
现在的石油钻井技术要求聚阴离子纤维素(简称PAC)具有更好的抗盐、抗钙、抗高温性能和明显的增粘作用。
