A compound, such as sodium peroxide, Na2O 2, that contains a peroxyl group and yields hydrogen peroxide when treated with an acid.

过氧化物：一种包含一个过氧团离子的化合物，Na2O 2，遇酸可生成过氧化氢，如过氧化钠

The reaction mechanism was discussed in view of both AC impedance and IR spectroscopic techniques.

因此，对硫氰酸根离子的测定和监控非常重要。

The barium-strontium titanyl oxalate precursor powder was prepared successfully by using the simple oxalate chemical coprecipitation method. The pyrolysis of BSTO at 905℃ in air produced barium-strontium titanate powder. BST powder was characterized with SEM, TEM, XRD and FT-IR, which revealed that the powder was spherical, highly pure, perovskite, and the average particle diameter was 36nm.

采用草酸盐化学共沉淀法制备了草酸氧钛锶钡前驱体，通过905℃高温煅烧，制得了高纯纳米钛酸锶钡，并利用SEM、TEM、FT-IR和XRD对其进行了表征；并将该粉体应用于水中重金属镉离子的吸附。

Syntheses of Grignard precursor, N - tert -butyl-4-chloro-piperidine, were accomplished via transamination with a quaternary ammonium piperidone or via addition of methylmagnesium chloride to an iminium ion.

氏体合成， N-叔丁基-4-氯哌啶、出自同一个经转氨酶哌季铵盐或透过增设methylmagnesium亚胺离子的氯化物。

Exe and the lattice parameter was smaller than that of the undoped one, which was decreased to some extent due to the doped-ion.

同时应用软件计算了其晶格常数，结果发现金属离子的掺杂不同程度地减少晶格大小。

It was found that the α and β peaks of the dielectric loss tangent coincided like a single peak and with higher permittivities,if the unneutralized copolymers were used as the parent materials.

离子化后，α和β两峰独立存在；随离子化程度提高，εr值下降，α和β峰都向高温移动；随同价反离子的半径增加，εr值增大，β峰向低温移动，但α峰变化不大。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
