由我校数力系物理试验室韩日范工程师多年研究,并与长春市第五光学仪器厂共同试制的WSC—1超声光栅声速仪,达到了吉林省机械电子厅下达的试制新产品计划任务书的要求,于1980年6月17～18日在吉林省机械电子厅主持下通过新产品鉴定。 WSC—1超声光栅声速仪是利用声光相互作用的原理,使超声驻波可见,然后通过升降液槽的方法,可以分别开设振幅栅法、二次干涉法及超声干涉法精确测定液体中声速的物理试验仪器。
The WSC-1 ultrasonic grating accelerometer, which was researched and manufactured by the Fifth Optical Instrument Factory of Changchun City for many years, was researched and developed by Han Riyan Fan, a number of physical laboratory of our school, and reached the trial plan of new product planned by Jilin Provincial Office of Mechatronics Requirements, in June 1980 from 17 to 18 in Jilin Province, under the auspices of the Office of Mechanical and electronic products through the identification of new products. WSC-1 ultrasonic grating accelerometer is the use of the principle of sound and light interaction, the ultrasonic standing wave can be seen, and then by lifting the tank method, you can set up an amplitude grating method, the second interference method and ultrasonic interferometry accurate measurement of liquid velocity Physical test equipment.
