一、前言皮肤是人体的大门,它复盖人体表面,激光治疗基本上必须首先通过皮肤而达到皮下组织和器官,激光防护重要内容之一是皮肤的防护。显而易见,研究皮肤对激光的反射、透射和吸收规律,是一项重要的基础研究,它将为研究激光的生物效应,研究激光的治疗和防护剂量,提供重要的参数。可惜,这方面的研究在国内我们只见到一例报导,它只是对单一 First, the foreword The skin is the gate of the human body, which covers the human body surface, laser treatment basically must first reach the skin and organs through the skin, laser protection, one of the important content is skin protection. Obviously, studying the law of the skin’s reflection, transmission and absorption of laser light is an important basic research. It will provide important parameters for studying the biological effect of laser, studying the laser treatment and protective dose. Unfortunately, we have only seen one case of this study in the country. It is only about unity
