field gradient meaning in English
场梯度
Examples
- When the rf pulse is combined with magnetic field gradients , a spatially encoded signal is produced that can be detected and translated into images
当射频脉冲与磁场梯度联合起来时，我们可以探测到一个空间编码信号的产生并且将它转变成图像。 - It has high selectivity in adsorpting water , polar molecule or polarizable molecule on account of the existing of mighty coulomb field and polar interaction in the internal of crystal cave of zeolite , the high electric field gradient and the uneven surface caused by the exposure of exchangable cation of equilibrium framework negative charge in framework structures
由于分子筛晶穴内部有强太原理工大学硕士学位论文摘要大的库仑场和极性作用，再加上骨架中大量平衡骨架负电荷的可交换阳离子的暴露造成的高电场梯度及表面的不均性，使其对水、极性分子及可极化的分子具有高选择的吸附性能。
