稀

One easy way to assemble molecules from a dilute solution is to concentrate them on a flat surface. Errant molecules might have been drawn to the calm surface of a tidal pool or perhaps to a primitive "oil slick" of compounds trapped at the water's surface.

从稀溶液中聚集分子有个简单方法，可在一个平坦表面上使分子聚集，游荡分子也许会跑到潮间池的水面，或者水面上类似浮油的化合物中。

研究表明，对于底部冷却的静态定向结晶过程，两相区低温稀溶液层的存在是形成双扩散对流的原因；双扩散对流的形成与发展造成液相区速度、温度和浓度呈盐指型分布，并促使两相区形成孔道流。

The metal sample is dissolved with HCl H 2O 2, and the dissolved nickel is separated from other activation products by anion exchange. Nickel is then complexed with pealetyldioxime in the alkaline solution, extracted with toluene, and finally determined by liquid scintillation counter.

先将样品用HCl H2 O2 溶液溶解、再经阴离子交换、氢氧化物沉淀分离后，在碱性溶液中用丁二酮肟配合镍、甲苯萃取、稀HCl反萃后再用液体闪烁计数器测定反萃液中6 3Ni放射性活度、原子吸收分光光度计测定金属中稳定镍。

Based on Pierre Becker's viewpoint of optimum m(active SiO2)/m=0.53, and combined with the production of 28% P2O5 phosphoric acid with Yunnan and Anning phosphate rock in the plant, the conclusion that the range of optimum m(active SiO2)/m covers 0.53～0.63 is drawn .

分析磷矿中不溶性SiO2和可溶性SiO2(即活性SiO2)对磷酸，磷铵生产的影响，根据皮埃尔贝凯提出磷矿中m(活性SiO2)/m=0.53较为合适的观点，结合该厂使用云南矿，安宁矿生产28% P2O5稀磷酸时，SiO2的分配情况，计算出m(活性SiO2)/m的范围是0.53～0.63。
