When the pH value of the solution contained in Cd~(2+) is near 5, the amount of Cd~(2+) exchange in analcime reaches to a summit; when the temperature increases, the amount of Cd~(2+) exchange in unit mass analcime also increases; when initial Cd~(2+) concentration decreases, the remove rate of Cd~(2+) increases while the amount of Cd~(2+) exchange in unit mass analcime also decreases; when other cations coexist in solution, there must be some influences to the Cd~(2+) exchange in analcime.

实验表明：当交换液的pH值为5左右时，方沸石对Cd~(2+)交换量较大：反应温度升高时，单位质量方沸石对Cd~(2+)交换量增大；随着溶液中Cd~(2+)初始浓度减小，方沸石对Cd~(2+)的去除率升高，但单位质量方沸石对Cd~(2+)的交换量逐渐减小；当溶液中有其他阳离子共存时，对方沸石与Cd~(2+)的交换也有一定的影响。

In the existing network's foundation, will gather slightly turning on to big gathering turning on reforming, the core backbone level does not make turning on principle, only makes the exchange, guaranteed that the IPv4/IPv6 network can simultaneously undertake IPv4 and the IPv6 exchange of information, guarantees its performance, reduces the promotion risk, the network analysis situs by original Shan Xing the analysis situs, changes the two stars analysis situs, the Integral part uses double turns over to turning on, guarantees the IPv4/IPv6 production network stably reliable.
