查询词典 oxide

It breaks out the traditional anode-oxidation technique of forming oxide coating according to Faradays law, and forms oxide coating in micro plasma areas. It has the characters of simply technique, high efficiency, no pollution, etc.

它突破了传统的阳极氧化在法拉第区内成膜的限制，可在微弧区中氧化成膜，而且它具有工艺简单、效率高、无污染、处理工件能力强等特点。

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。

In the first stage, anaerobic hydrogen depolarization is predominant and produced iron oxide corrosion product layer; in the second stage, due to bio-produced hydrogen sulphide, iron oxide was biomineralized and translated iron sulphide.

初期是厌氧条件下的氢去极化，生成氧化物产物层；然后在SRB代谢产生的H2S作用下，发生氧化物到硫化物的转变。

Intend to use the most advanced technologies in building the 20,000 t/y propylene oxide plant, hydrogen peroxide and propylene as raw materials. Process control using phase transfer catalyst reaction of propylene oxide technology, non-polluting, non-joint products.

拟采用国内先进技术建设2万吨/年环氧丙烷生产装置，以双氧水和丙烯为主要原料，生产工艺采用反应控制相转移催化丙烯氧化技术，无污染、无联产品。

铁锰氧化物结合态铁、铜对有效态铁、铜及碳酸盐结合态锰、锌对有效锰、锌具有一定正效应。

For the fly ash with high iron oxide concrete also brought more iron oxide, it contributed much to the density that primarily determined the conductivity from liquid ionic conducting.

对于高铁的氧化物混凝土也带来了更多的铁氧化物粉煤灰，它很大的贡献是主要决定进行的离子导电性液体密度。
