查询词典 Valence

It can be proposed that the chargecompensation effect between Co~(2+) and Ti~(4+) ions in raw materials make them tendto co-occupy uniformly B site in perovskite both as the forms of +3 valence, which isresponsible for the lower temperature synthesis.

分析认为，原料中的Co~(2+)和Ti~(4+)离子通过电荷补偿作用(charge compensation effect，CCE)使二者均易于形成Co~(3+)和Ti~(3+)离子去共同占据ABO_3型钙钛矿结构的B位，这种电荷补偿作用导致样品具有较低的合成温度。

The preparative technique of solid lubricant is cold-press sintering method.The micro-structure , friction surface, lubricant transfer film surface of base material was characterized by SEM; XRD was used to do phase analysis. The degrees of crystallinity of pure PTFE under the different conditions of water cooling, air cooling and furnace-varying cooling were made comparison by XRD. The thermal stability of pure PTFE and solid lubricant was analyzed by DSC-TG; The composition and valence state of elements in the surface of carbon fiber ,solid lubricant before and after friction test and lubricant transfer film were characterized by XPS; The frictional property of solid lubricant was tested by pin and disk test rig .

Ordinary questions of discipline are in the ordinary course settled in councils, often held with the assent of the kings, but on great occasions -- at the Councils of Epaone (517), of Vaison (529), of Valence (529), of Orléans (538), of Tours (567)-- the bishops do not fail to declare that they are acting under the impulse of the Holy See, or defer to its admonitions; they take pride in the approbation of the pope; they cause his name to be read aloud in the churches, just as is done in Italy and in Africa they cite his decretals as a source of ecclesiastical law; they show indignation at the mere idea that anyone should fail in consideration for them.

普通的纪律问题是正常经营过程中解决的理事会，往往与同意的国王，但在伟大的场合-在议会E paone（ 5 17），对V aison（ 5 29），价（ 5 29），中奥尔良（ 538人），图尔（ 567 ）-主教不失败宣布，他们正在采取行动的冲动下的罗马教廷，或推迟到告诫他们感到自豪的认可，教皇；它们所造成的名称朗读的教堂，就像是在意大利和非洲，他们列举了decretals作为一个来源的教会法；它们显示愤慨，仅仅是想法，任何人不应该考虑他们。
