我校生物课外活动小组采用比较简便的方法,试制了各种小型脊椎动物骨胳透明标本。这类标本比干制标本具有更明显的直观性。同时,还试制了植物输导组织透明标本和人的胚胎骨胳透明标本。1985年参加省、地、市的评比活动中,这些标本获得一等奖。
The biological extracurricular activity team of our school used a relatively simple method to trial production of various small vertebrate bone transparent specimens. Such specimens are more intuitive than dry specimens. At the same time, transparent specimens of plant-transport tissue and human embryonic osseous specimens were also prototyped. In 1985, they participated in competitions in provinces, cities and cities. These specimens won the first prize.
