Methods:Mixing up plasma specimens and hemoglobin solution, the carbon monoxide in plasma is trapped with hemoglobin and then be estimated by a two-wavelength spectrophotometry.

方法：血浆标本与血红蛋白溶液混合后，其中的一氧化碳与血红蛋白结合，再用双波长分光光度法进行测定。

In addition, the plasma bombardment induces the charge traps into the near-surface, which make the trapped charge stored stably.

另外，等离子体轰击在薄膜的近表面引入了电荷陷阱，使俘获的驻极化电荷能较稳定地保存。
