It is proposed that the appearance of a new kind of mud additive can not represent the formation of a new mud system . The main influence factors of flow resistance at drill bit nozzle are solid content , particle size distribution and hydrophilicity of solid . It is not suitable to use high shear viscosity of both Casson rheology model and determined to predict drilling efficiency .

全面、系统地论述了处理剂和泥浆体系的关系；聚合物的使用浓度应突破全絮凝点，实现低固相应以发挥聚合物的抑制作用为主，絮凝作用为辅；影响钻头水眼处流动阻力的主要因素是泥浆中的固相含量、粒度分布及固相的亲水性，用η_∞代表钻头水眼粘度是欠妥的；聚合物泥浆处理剂的发展主要是开发新的单体和研究新的复配物。

Since the liquid ink includes the colorant surface-treated by a polymer comprising units derived from at least a nitrogen-containing polymerizable monomer, it exhibits improved chargeability, reduced conductivity variability and improved dispersion stability at a lower amount of charge control additive.

因为该液体墨水含有用聚合物进行表面处理的着色剂，该聚合物含有的单元来自至少一种含氮的可聚合单体，所以在较少量电荷控制添加剂时，它具有改善的荷电率，降低的导电率可变性以及改善的分散稳定性。

And it is also a check point to understand the physical chemical properties of the unique aggregates.

在没有外加能量的条件下，由单体分子、胶束或双层膜如何自发转变为囊泡，以及自发形成的囊泡的稳定性一直是近期研究的热点，也是弄清这一特殊的聚集体的物理化学性质的瓶颈。
