After 48h of exposure, the color of leaf of Egeria najas became greenish badly and the leaf was conglutinated, and the chlorophyll content of leaf declined significantly when the Hg concentration were above 2.00mg/L.By the changes of chlorophyll content, the lethal concentration of Hg to Egeria najas was 0.10-2.00mg/L.

处理48h以后，Hg~(2 )浓度人于1.00mg/L实验组中的叶片褪绿严重而且叶片相互粘连，叶片叶绿素含量明显低于对照组，从中可以粗略看出Hg(2-)对细叶蜈蚣草的致死浓度为0.10-2.00mg/L。

Result Based on directly regenerated plant of in vitro plant of Xinjiang cotton, the cotton epicotyl treated by pre-culture for 3-5 d was immersed in bacteria for 15 min and co-cultured for 2 d. Cephalothin at 100 mg/L was used to inhibit bacteria after 50 mg/L kan selection. And the combination of cytokinin with relatively high content and auxin with low content was used in its directly budding culture to obtain resistant seedlings.

结果］在新疆棉花离体培养植株直接再生植株基础上，经3~5d预培养处理过的棉花上胚轴，在浸菌15 min共培养2 d后，经50 mg/L kan筛选，用1000 mg/L头孢霉素抑菌，并用相对高含量细胞分裂素和低含量生长素的组合对其进行直接出芽培养，从而获得抗性小苗。

If Q and R are equidistant from L, find the equation of L.

b 若 Q 及 R 至 L的距离相等，试求 L的方程。
