For that question: how a probability event becomes to be a certainty event after some time.The answerer is that the Probability is changing along the development of time since many factors will affect the Probability in that time interval and Probability=1 at the point it happened.

又如生化反应，在刚开始的时候，那些化学物质发生反应的概率可能很小，加入催化剂（或者即使不加入催化剂，由于各物质的溶度随着反应进行，时间的推移而改变）影响着后来某一时刻这些化学物质能否完全反应。

Cyclic voltammetry indicated that there were Cr→Cr, Cr →Cr oxidation reaction on anode, while there were Cr→Cr, Cr→Cr, Cr →Cr deoxidization reaction on cathode. The graphite electrodes treated by acid and heating could enhance the reversibility and kinetic of the electrode reaction. The nature graphite electrodes had been eroded during charge/discharge process, while the graphite electrodes by activation could avoide corroding by hexad chromium ion. The reversibility and kinetic of the electrode reaction of chromium ion on activation electrode had been increased, so which indicated that graphite surface augment oxygenous function corps which could increase electrode hydrophile capability.

循环伏安实验表明：铬液流电池的电极反应非常复杂，在阳极存在Cr→Cr，Cr→Cr的氧化反应，在阴极存在Cr→Cr，Cr→Cr，Cr→Cr的还原反应；热处理的石墨电极和重铬酸钾处理的石墨电极能提高电极反应的活性和可逆性；在充放电实验中未处理的石墨电极发生严重腐蚀；分别用这两种方法处理过的石墨电极具有防止六价铬侵蚀的功能；铬离子在活化处理过的石墨电极上的反应活性和可逆性增加，可以认为：重铬酸钾溶液活化处理和加热处理后的石墨表面的含氧官能团增加，电极亲水性增强。

The copper-catalyzed 1,3-dipolar cycloaddition of alkynes with azides is a typical example of "click" reaction.1 Since the reaction enjoys the advantages of high efficiency and regioselectivity and requires mild reaction conditions and simple purification procedures, it has become a versatile synthetic tool with applicability in diverse areas including bioconjugation and surface modification.2 The click reaction has also been utilized in polymer science with emphasis on the functionalization of preformed polymers through postpolymerization approaches.3 The effort of developing the reaction into a new polymerization technique, however, has met with only limited success.
