nonstoichiometric

After the precursor's thermal decomposition under the protection of nitrogen,a kind of nonstoichiometric titanium oxide can be prepared.

用钛粉和应制得前驱物,在氮气保护下600℃热分解前驱物制备了一种非化学计量钛氧化物。

In the presence of impurities or in a nonstoichiometric solid, free electrons or electron holes are produced as a result of “charge compensation” to neutralize the effect of charged ionic defects 。

在杂质存在情况下，或在非化学计量比固体中，为了中和带电离子缺陷所引起电荷不平衡，便会产电子或电子空穴。
