On the glass waveguide formed by ion exchange, a silver metal layer is deposited, thereby the graded refractive index waveguide with metal-cladding is made. 在离子交换玻璃波导上,沉积一层金属Ag,制成带金属包复的渐变折射率波导。
Ion exchange properties of semi-crystal stannic phosphate-thin layer electrophoretic behaviour of some noble metal ions 半晶型磷酸锡离子交换剂的应用&部分贵金属离子的薄层电泳分离
The effect of Cystine on the curves of ion exchange ratio E%-pH in the interaction between Pb ( II) and the surface layer sediment in the Yellow River was studied. 研究了胱氨酸的浓度对黄河水中铅(Ⅱ)与表层沉积物相互作用的离子交换率―pH关系曲线的影响。
Ion exchange resin can be conveyed continuously and timely. Resin bed can move down evenly in a stable status without layer confusion. 操作实验过程中设备运行稳定,操作方便,离子交换树脂可以连续及时地转移和输送,树脂床层能以稳定状态均匀下移而无乱层现象。
