味觉检查广泛用于健康检查及神经科、耳鼻喉科的临床与生理病理基础研究。一般使用化学法,以酸、甜、苦、咸溶液测定味觉功能,不能作定量测定,容易产生误差。1958年Krarup提出的电测味法弥补了化学法的不足,但因仪器结构上的原因,检查结果不够稳定。七十年代后期,国外较普遍地开展了电测味法的研究,并在测试仪器等 Taste examination is widely used in health examination and neurology, otolaryngology clinical and physiological and pathological basic research. General use of chemical methods to acid, sweet, bitter and salty solution determination of taste function, can not be measured quantitatively, prone to error. In 1958, Krarup proposed the electrical measurement of taste to make up for the lack of chemical method, but due to structural reasons, the test results are not stable enough. The late seventies, foreign countries more commonly carried out the study of electrical measurement of taste, and in the test equipment
