1. 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。
2. It is found that the canonical momentum is directly proportional to the gradient of space phase. 发现正则动量与空间相的梯度成正比。
3. Zinnwaldite can be separated effectively by the high gradient magnetic separation from the tailing. 采用高梯度磁选可将铁锂云母从尾矿中有效分离。
