Salts are enriched around electriferous groups of polymer molecules in solution, which formed a salt concentration gradient.
溶液中的盐份富集在聚合物分子的带电基团附近，并形成盐浓度梯度分布。
To further confirm their results, the researchers grew bacterial colonies near wells filled with a solution of ammonia and found the same slime gradient.
为了进一步确认这一实验结果，研究人员在孔附近充满氨溶液的培养基种培养细菌菌落，发现了同样的粘液梯度。
The scheme can keep the large gradient variation of the original solution and can also save computation time. So, it has some value in theory and application.
这种格式既能保证原解的大梯度变化的性质，又能节省计算时间，因而具有一定的理论与应用价值。
