图11教具装置图(见图1)2仪器特点及用途(1)特点本教具装置简单,学生操作显微镜观察显微材料时不受任何外界光源的影响。不仅制造成本低廉,日常实验学习过程中使用显微镜的应用成本同样十分低廉,可用于改造各中小学现有的学生光学显微镜,节约学校替换实验设备的成本,符合节能减
Figure 11 aids device diagram (see Figure 1) 2 features and uses of the instrument (1) Features The teaching aids are simple, students operate the microscope to observe the microscopic material without any external light source. Not only the manufacturing cost is low, but also the application cost of using the microscope in the daily experimental learning process is also very low. The utility model can be used to transform the existing student optical microscopes in all primary and secondary schools, save the cost of replacing the experimental equipment in schools,
