藤壶幼虫

For example, seaweeds may never be able to colonize a patch if barnacle larvae get there first Fig.

例如海藻可能永远无法殖民化的修补程序，如藤壶幼虫那里(图 11.14)第。

The toxicity of MOP-DCI for nauplii of barnacle was further examined.The 24 h-LC_(50) is 95.50 μg/L.

并通过生物毒性实验得出其对藤壶幼虫24 h的半致死质量浓度为95.50μg/L。

If the patch opens up when barnacle larvae are abundant and seaweed spores are rare, the barnacles have the upper hand.

如果启用时，此修补程序藤壶幼虫有大量及海藻孢子均为罕见，在 barnacles，上风。

The linear relationship between creaturely activity for alcohol, aether, ketone and ester and the molecular topological index is obtained.

研究了醇、醚、酮和酯对水生生物毒性、蝌蚪麻醉活性、沙镯幼虫麻醉活性、番茄植物毒性、红蜘蛛毒性、藤壶幼虫麻醉活性、局部麻醉剂活性和小鼠毒性等八种生物活性分别同其分子连接性指数的相关性。

Experiment results showed as follows: 1 Two kinds of reactive oxygen species exhibited remarkable damage to larvae on 3 types of different development stage.The treatment of reactive oxygen species could result in decrease of larva survival rate and inhibit metamorphosis rate of cyprid.

实验结果表明：1、二种类型的活性氧对东方小藤壶三种不同发育时期的幼虫均具有伤害作用，在其作用下，幼虫存活率的下降，变态过程受到抑制，且表现出一定的剂量效应；三种不同发育时期的幼虫对活性氧作用的敏感性存有明显的差异性，Ⅵ期无节幼虫对羟自由基的作用最为敏感。

The larvae on different development stage indicated different sensitivity to reactive oxygen species, the napuli VI showed the most sensitive. 2 Antioxidants could decrease the damage effect of reactive oxygen species on larvae in certain level.The addition of antioxidants in culture system had risen larva suvival rate and the metamorphosis rate of cyprid .

外源抗氧化剂的加入在一定程度上减弱了活性氧对东方小藤壶幼虫的伤害作用，从而提高了幼虫的存活率和变态率；在减弱活性氧对东方小藤壶幼虫的伤害作用中，不同类型的抗氧化剂对不同类型的活性氧所起的作用大小不同。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
