survival curve

The survival curve indicated that the population decrease uses mainly from egg to lst and 2nd instar.

从种群存活曲线分析得出，影响种群增长的关键虫期为卵至1、2龄幼虫期；

Kaplan-Meier method was used to estimate survival curve.

Kaplan-Keier法估计生存曲线。

The recurrence rate and survival curve of the positive and negative margin group were compared;

比较切缘阴性组与阳性组的复发率、生存曲线；

The Dq value of the cell survival curve was 2.152 for 973 and 0.626 for CNE-1 cell line detected by the colony assay, which indicates that the sublethal damage repair in 973 cells being much faster than in CNE-1 cells.

细胞存活曲线显示，973细胞的Dq值为2.152，CNE1细胞的Dq值为0.626，提示973细胞的亚致死损伤修复能力大于CNE1细胞。
