在化学实验中要用到大量试剂瓶,每1个试剂瓶都有1个标签。由于各种原因,标签常常被损坏。例如倒试剂的方法不正确,试剂残留液流到标签上,在使用中水溅到标签上,一些学生乱涂乱改等。这给实验带来了许多不便,也给实验员增加了一定的工作量。笔者在工作中对贴试剂瓶标签的方法进行了改进。具体的做法如下: A large number of reagent bottles are used in chemical experiments. Each reagent bottle has a label. For various reasons, labels are often damaged. For example, the method of pouring the reagent is not correct, the residual liquid of the reagent flows on the label, and the water splashes on the label during use, and some students randomly mess up. This brought a lot of inconvenience to the experiment and also added a certain amount of work to the experimenter. The author has improved the method of labeling reagent bottles in the work. The specific approach is as follows:
