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

1.用钛粉和草酸反应制得前驱物,在氮气保护600℃解前驱物制备了一种非化计量钛氧化物。

2.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 。

2.在杂质存在，或在非化计量比固体中，为了中和带电离子缺陷所引起电荷不平衡，便会产生自由电子或电子空穴。
