成核势垒 meaning in English
nucleation barrier
Examples
- The seemingly mcnt content in pt can be controlled by repeating the coatings of the film and increasing the mcnt doped concentration of the sol . the heterogeneous nucleation at the interface between mcnt and pt was induced by the doption of mcnt . the films which were calcined at 500 ? had formed perovskite and large crystal content , means that perovskite formed at the lower temperature , in conclusion , the crystalline ability of pt was improved by the doption of tb and mcnt
纳米碳管的引入，使得体系在纳米碳管和pt之间的界面产生非均态核化，随pt薄膜成核势垒的降低，掺纳米碳管的pt薄膜在较低温度下即可形成钙钛矿相，在500的较低温度，就可获得结晶完整且己具有很大结晶量的薄膜。
