两步法

• In the paper , the two - step approach , in which the deposition procedure was divided into two sections by decrease the substrate temperature or the bias voltage , was used in order to synthesize c - bn film by the conventional js - 450a rf system . the influence of process parameters for nucleation and growth of depositing c - bn was studied separately

• ( 2 ) two methods including one - step and two - step methods were used to modify the platinum electrode . in the two - step method , the experiment conditions were confirmed , namely after modified by nafion film , the electrode was dipped in saturated solution of co ( salen ) for 24h . the electric current would decrease if the dipping time were too long
  2 .用两科，方法对电极进行co ( salen ) / nafion修饰，即“一步法”和“两步法” ，对“两步法”的实验条件进行了选择，即将电极表面先修饰好nafion膜后，再浸泡在co ( sa1en )饱和溶液中24h即可，时间再长则峰电流反而会减小。
