生物系液晶研究组最近研制成功了液晶固定膜和液晶检测激光屏。液晶研究组过去进行的液晶诊断浅层肿瘤的研究成果1971年后已逐渐应用于临床。由于该诊断方法简便可靠,对病人无痛苦、无付作用,所以深受广大医务工作者和工农兵的欢迎。但在临床使用中也存在一定的不足之处,如诊断肿瘤时需随用随配液晶涂液、诊断后不 Department of Biology LCD Research Group has successfully developed a liquid crystal fixed film and liquid crystal detection laser screen. LCD research group conducted in the past LCD diagnosis of superficial tumors of the research results after 1971 has been gradually applied to clinical. As the diagnostic method is simple and reliable, no pain on the patient, no pay, so by the majority of medical workers and workers and peasants welcome. However, there are also some shortcomings in clinical use, such as the need to use with the liquid crystal coating solution for diagnosis of the tumor, the diagnosis is not
