“崇尚科学爱我中华”第九届全国少儿书画大赛暨青少年发明创新大赛来稿选登在一些中小学的实验室里,老师目前使用的还是这种试管架(图1)。它使用方便,但只适用于晾那些口径较小的试管,且只能同时晾少量试管。此外,使用这种试管架晾试管时,沥到试管架底盘的水蒸发后可能回到试管内,影响晾干效果。我们细心观察生活,受插糖葫芦的草垛子启发,设计了一款玻璃仪器晾干架。经过多次修改,我们在老师和电工师傅帮助下制作出一种新型玻璃仪器晾干架。
“Advocating science love me China ” Ninth National Children’s Painting and Calligraphy Contest and young people invention and innovation contest manuscript selected boarding in some primary and secondary laboratory, the teacher is still using this test tube rack (Figure 1). It is easy to use, but only for those smaller caliber tubes, and can only be used to dry small tubes at the same time. In addition, when using this tube rack to dry the test tube, the water leaking to the rack of the test tube holder may evaporate into the test tube and affect the drying effect. We carefully observe the life, inspired by the grasshopper inserted sugar hyacinth, designed a glass drying rack. After many revisions, we created a new type of glassware drying rack with the help of a teacher and an electrician.
