碲化物

The low temperature solvothermal route was extended to synthesize nanocrystalline tellurides.

发展了低温溶剂热合成碲化物纳米晶的技术。

It is the first example foundin tellurides that the third component inserts the intra-layer region as well as the interlayer one. This statisticoccupation of Ni atom between layers also produces variouschemical environments around metal and non-metal atoms in thiscompound.

第三组元金属插入层内的同时也插入层间，这在碲化物中是很少见到，并使该化合物中金属和非金属的局部化学环境多样化。

Under atmospheric pressure, binary nanocrystalline sulfides and selenides such as CdS、CdSe、PbS、 PbSe、Cu〓Se、Ag〓S、Ag〓Se、SnSe are obtained at room temperature; nanocrystalline CdTe and PbTe are obtained by heating. Nanocrystalline NiSe〓、CoSe〓 and FeTe〓 are obtained by hydrothermal conditions.

根据硫、硒歧化的碱溶液与碲歧化的碱溶液稳定性的不同，发现在室温条件下可成功获得CdS、CdSe、PbS、PbSe、Cu〓Se、Ag〓S、Ag〓Se、SnSe等二元硫化物与硒化物纳米晶；加热条件下可成功获得CdTe与PbTe纳米晶；而NiSe〓、CoSe〓及FeTe〓的合成则要在水热条件下进行。

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。
