我们在省科委的直接关怀和领导下,以三结合的形式,开展了激光新技术在医学上的应用研究。遵照毛主席的教导,我们在研究工作中发扬了自力更生、艰苦奋斗的革命精神,于1975年研制成功了二氧化碳激光手术器。在此基础上,我们坚持“由实践到认识,由认识到实践”的辩证唯物主义认识论的观点,不断“总结经验,克服困难”, We are under the direct care and leadership of the Provincial Science and Technology Commission, in the form of three combinations, launched a new laser technology in medical research. Following Chairman Mao’s teachings, we carried forward the revolutionary spirit of self-reliance and hard work in our research work. In 1975, we successfully developed a carbon dioxide laser surgical instrument. On this basis, we uphold the viewpoints of dialectical materialistic epistemology “from practice to understanding and from recognition to practice”, continuously “summarizing experiences and overcoming difficulties”
