| 摘要: |
| 采用改良后的沉淀集卵法对低（10个/100 g）、中（20个/100 g）、高（40个/100 g）3种不同浓度的加标样品进行蛔虫卵检测，比较其回收率。结果表明：不同浓度加标样品的回收率为高浓度＞中浓度＞低浓度。与相关文献实验结果比较表明，该方法不仅回收率较高、稳定性较好，且在检测低浓度样品时较漂浮集卵法具有一定优势。 |

| Abstract: |
| Modified sedimentation method was applied for detecting ascaris eggs in low (10 eggs per 100g), medium (20 eggs per 100g) and high (40 eggs per 100g) concentrations. Comparison of the recoveries at these three different spiked levels, high concentration ones had the highest recovery, followed by medium concentration ones, and low concentration ones.Compared with the experimental results in references,the recovery of this method was higher, and the stability was better. Also，this method was more appropriate for detecting samples in low concentration than flotation method. |
