关于振动病的流行病学研究,早年仅限于接触振动工具工人的患病率或病因学的一般调查。近年振动病流行病学研究已深入到接触振动时间(以下简称接振时间)与振动危害关系,即振动病的剂量与反应,素质性白指(Constitutional white finger CWF)与振动病白指(Vibrational white Epidemiological studies on vibratory diseases were limited to the general investigation of the prevalence or etiology of workers exposed to vibration in the early years. In recent years, the epidemiological study of vibrational disease has been deep into the contact vibration time (hereinafter referred to as the vibration absorption time) and the relationship between the vibration hazard, namely the vibrational dose and response, the constitutional white finger (Constitutional white finger CWF) and Vibrational white index white
