求翻译：但传统的高吸水性树脂大多是由丙烯酸或丙烯酰胺等单体聚合而成，在实际应用中存在着生产成本高、耐盐性差等缺点，采用无机材料制备复合高吸水性树脂可以弥补以上不足。是什么意思？

Traditional superabsorbent mostly from acrylic acid or acrylamide monomer polymerization, in practical applications there are high production costs, the salt tolerance of defects and poor, more than the preparation of inorganic materials can make up the composite high absorbent resin inadequate.

However, traditional high water absorbency is mostly consists of acrylic resin or acrylamide monomer such as aggregates in a practical application, there is a high production costs, and poor resistance to salt of shortcomings in inorganic materials, preparation of composite high water absorption res

But the traditional high hygroscopicity resin mostly is by monomer polymerizations and so on the acrylic acid or acrylic amide becomes, has the production cost high in the practical application, the salt endurance inferior shortcoming, uses the inorganic material preparation compound high hygroscopi

Traditions most of the high absorbent resin by polymerization of acrylic acid and acrylamide monomer is formed, in practice there are high production costs, poor salt tolerance of defects, using inorganic materials can more than make up for the lack of preparation of superabsorbent resin.
