这两种衰减速率一致光组合成我们所看到的白光，为色稳定性的近紫外芯片激发的余辉二极管的制备提供了依据。

The same decay rate of two kind of light are verified to combine the white light uniformly, providing the possibility for fabricating long aftergolow WLED with color stability during decay.

如果碳纳米管阴极附近的真空度太低，将产生打火、气体电离、离子回轰阴极等问题，将导致阴极发射电流的迅速衰减。

If the vacuum near the cathode is too poor, it will generate spark, gas ionization and ion bombardment on cathode, which can result in a fast attenuation of the emission current.
