1.The orientation is combined with relatively long spacings to give deeper penetration, and hence less effect of mud cake or rugosity.
使用偶极子作为传感器，沿仪器轴向定向排列，相对长源距，探测深度大，从而减小泥饼和井壁不规则的影响。
2.Some virulent strains of PVX cause rugosity go the leaves even crinkling, called PVX crinkle.
PVX的有些强毒株系引起叶子的粗缩甚至皱缩，叫做PVX皱缩。
