病证名。指五脏精气内虚,为邪气所兼并而出现的精神症状。《素问·宣明五气篇》:“精气并于心则喜,并于肺则悲,并于肝则忧,并于脾则畏,并于肾则恐,是谓五并,虚而相并者也。”
Well, a cross-sectional study would mean that you'd get a random group of the population and measure them in 1970 and then take another random group five years later and measure them, but it wouldn't be the same people necessarily, it would be different groups of people.
那么,横断面研究就是,1970年你在人群中随意选择一组人,并记录下相关数据,然后,五年后再随意选择一组人记录数据,但这不需要是同一组人,通常是不同的人
