肠道蠕虫（钩、鞭虫）感染的患者,感染度越低,用定透法检查粪便蠕虫卵的检漏率越高。本文用指数曲线拟合法,找出用两法（定透法与盐浮法）联合检查均为阳性感染者中,单用定透法的检漏率与肠道钩、鞭虫不同感染度的数量变化关系,并建立了推算检漏人数的公式。 Intestinal worm (hook, whipworm) infected patients, the lower the level of infection, fixed stool method to check the higher the leak rate of stool eggs. In this paper, exponential curve fitting method to find out by the two methods (Dingtong method and salt float method) were positive for the joint inspection, the single fixed-law leak rate and gut hook, whipworm different degrees of infection The relationship between the number of changes, and established a formula to estimate the number of leaks.
