查询词典 vanadium oxide

The observed EMF values of oxygen concentration cell coincided withtheoretical values perfectly, indicating that the ceramics were purely oxide-ionicconductors with oxygen ion transference number of 1 under oxygen atmosphere over thewhole temperature range. The electrochemical oxygen permeation rates determined were inaccordance with the theoretical rates calculated from Faradays law, verifying directexperimentally that the oxide-ionic nature of the conduction under oxygen atmosphere. Athigh oxygen partialpressure range pO_2=10~(-5～10~5 Pa, they were almost pure ionicconductors, which was consistent with the result by means of oxygen concentration cell.Whereas at low oxygen partial pressure range pO_2=10~(-5～10~(-15)Pa, the samplesexhibited mixed ionic and electronic conduction.

结果表明，氧浓差电池电动势的实测值与理论值吻合得很好，氧离子迁移数为1，表明该系列样品在该温度下氧气气氛中为纯氧离子导体；氧泵实验结果进一步证实了该系列样品在氧气气氛中为纯氧离子导体；在氧分压pO_2=10~(-5)～10~5 Pa的高氧分压气氛中，电导率与氧分压变化基本无关，表明在该氧分压范围样品为纯离子导体，这与氧浓差电池电动势测定结果相吻合：在低氧分压为10~(-5)～10~(-15) Pa范围，总电导率随氧分压降低而稍有升高，表明在该氧分压范围样品为氧离子与电子的混合导体。

The poor endurance is ascribed to the poor quality of TEOS used for the tunneling oxide as well as the horn-shaped channel. The traps are easily generated because of poor quality of TEOS. Besides, high electric field due to the horn of the channel could seriously damage the tunneling oxide.

耐久性差的主要原因，是因为使用TEOS当作穿隧氧化层，而TEOS的品质较乾氧化层差，容易产生缺陷；再加上因为通道尖角造成的局部大电场会对穿隧氧化层造成极大的伤害，所以特性并不理想。

On the basis of the masteries for the aluminum oxide ore pulp drying and calcination, a mathematical model was developed for simulating the process of heat transfer and the calcination of two-phase flow in a new type furnace designed by Zhongzhou Branch Company, China Aluminium Corporation Limited. The fields of velocity, temperature and pressure of the two-phase flow and the reaction time were gained by optimizing calculation under the condition of different operational parameters and geometric parameters. The effect of vent position velocity and atomization particle diameter on the drying and calcination technology of aluminum oxide ore pulp was discussed.
