The examination falls into two parts: the written test and the operation test. The written test is to check one's basic electric knowledge, which includes electric control theories, installation standards, etc. The operation test is a bit difficulty. Firstly, you have to connect several major loops and control loops appointed by the examiner within limited time. If you do right, the electricity is connected, the bell rings and the light turns on, then you will pass the test; but if it explodes and emits smoke, then you will not only get zero score but be scolded. Life is not a game, and one should never pretend to know things that he does not know.

考试分笔试和操作二项，笔试的内容都是最基本的电工知识，电气控制原理，电气安装规范等等，而考操作就有难度了，首先要你在规定的时间里接好考官指定几的主回路和控制回路，接对了，通上电，灯亮铃响顺利过关；若是爆炸冒烟，那不仅没分还要挨骂，生命不可儿戏，不懂不能装懂。

At the same time, the intensity ratio of the ICT fluorescence to the LE fluorescence, I〓/I〓, shows a "bell"-shaped variation with increasing CTAB concentration The intensity ratio was found to level off after the CMC of CTAB Together with the data from UV-Vis absorption spectroscopy, electric conductance measurements and the control experiments with tetramethylammonium bromide, it was concluded that the"bell"-shaped variation in the intensity ratio before CMC is due to the formation of premicelle aggregates consisting of ICT fluorophore and CTAB.

此时，ICT荧光强度与LE荧光强度之比，I〓/I〓随CTAB浓度增大而呈&钟形&变化。当CTAB浓度高于CMC时，I〓/I〓为一常数。根据紫外-可见吸收光谱，电导以及四甲基溴化铵对照实验的结果可知，当CTAB浓度低于其CMC时，I〓/I〓的&钟形&变化是由于长链对二烷基氨基苯甲酸与CTAB组成的胶束前簇集体形成所致。
