The immobilizing effects of red mud by bayer process is much better than by sintering process under different concentration of application, because of the smaller particle size, larger surface area, higher content of Fe2O3 and Al2O3.The adsorption capacity of red mud and zeolite to Cd was very large.

通过钝化剂对溶液中Cd离子的吸附解吸试验表明：赤泥、沸石对Cd离子具有很大的吸附容量和较强的吸附亲和力；只有不到25%的吸附镉为水溶态和可交换态，而绝大部分吸附的镉(50%以上)为与赤泥结合稳定的、不易为生物利用的形态。

The adsorbed ability of chaff to the heavy metals ion excelled that of beer yeast.

谷壳对重金属离子的吸附效果好于酵母菌对重金属离子的吸附。

The mPSCs induced by GABA released from the presynaptic boutons could be completely and reversibly blocked by 5μM bicuculline, which is the specific antagonist of GABAA receptor. These results indicate that GABA released from the presynaptic boutons may produce modulatory effects through binding with GABAA receptor on postsynaptic Vme neurons.

以上结果表明：突触前终扣内释放的GABA与分布于突触后的GABAA受体结合从而发挥对Vme神经元的调控作用，GABAA受体激活后，氯离子通道开放，Vme神经元胞体内外氯离子流动构成了GABA对Vme神经元的作用基础。

The influence of the doped content of Tb3+ ions on the emission intensity was also investigated and the concentration quench occurs when the doped content of Tb3+ ions is beyond 9%, which can be explained by electric multipole-multipole interaction according to Dexters theory.

考察了掺杂离子浓度对样品发光效率的影响，Tb3+的最佳掺杂摩尔分数为9%，分析了其自身浓度猝灭机理，探讨了敏化剂Ce3+离子的加入对荧光粉发光强度的影响。

And 17 were capable of detecting specific metal ions by showing dramatic enhancement of fluorescence. In contrast with 15 and 17, the fluorescence signals of 13 and 14 were inefficiently altered by metal ions. Hence, 15 and 17 were further investigated with detailed 1H-NMR, UV-vis, and fluorescence titrations.

其中，15和17对特定金属离子有明显的侦测能力，混合后萤光强度会大幅增强，但13及14与金属离子混合后，萤光讯号的改变幅度不如15及17的显著，因此我们只对15和17进行详细的1H-NMR、UV-vis及萤光光谱的滴定。

Then we introduce theory of ion-exchange process and how to design multimode Y branch optical splitters. Lastly we do some experiment of how to fabricate the device with Li~+-Na~+ ion-exchange technology.
