在近代生物医学的研究中,超薄切片机能连续地切出厚度为100埃左右的薄片,供电子显微镜探查生物组织的微细结构。但是仪器在长期使用中,由于电子器件的老化,电阻和电容的变值等原因,经常使机器的运转出现异常,从而影响切片的质量。如果切片厚薄不均匀,则在显微镜下能看到薄片的颜色深浅不一,这样成品率就低,需要进行检修和调整。由于医院条件有限,我们仅使用SBD-1型示波器、500型万用表和秒表等简易设备,经仔细调试后,
In modern biomedical research, ultrathin microtomes can continuously slice a sheet of about 100 angstroms in thickness and use electron microscopy to examine the microstructure of biological tissues. However, in the long-term use of the instrument, abnormal operation of the machine is often caused due to the aging of the electronic device, the change of the resistance and the capacitance, and the quality of slicing is affected. If the slice thickness is not uniform, you can see the color depth of the slice under the microscope, so the yield is low, need to be overhauled and adjusted. Due to the limited hospital conditions, we only use SBD-1 type oscilloscope, 500 multimeter and stopwatch and other simple equipment, after careful debugging,
