The tail fin with two degrees of the robot-fish under the change of heavy load and the influence of characteristic of electromotor will make the distortion of transformation of speed and position synchronously, and bring on anisomerous flaping of the tail fin.

机器鱼多关节尾鳍受外界负载变化及伺服系统机械结构本身特性的影响会使速度和位置曲线失真，从而影响机器鱼的推进效率。

While two herbicides had no significant effects on the growth of three cyanobacteria at low concentrations (0.01~0.001mg/L), they made damage to cells and affect cyanobacteria's growth at high concentrations (10~100mg/L). EC_(50) values of three cyanobacteria were showed below: Anabaena azollae, 3.172 mg/L; Anabaena azotic, 3.654 mg/L and Anabaena flos-aquae, 3.377mg/L Nitrogenase activities of three species also showed different tolerant capabilities to the two herbicides under 10% vol.

在低浓度(0.01~0.001mg/L)的2种除草剂的作用下，3种固氮蓝藻的生长没有受到明显的影响，而在高浓度下(10~100mg/L)，固氮蓝藻藻细胞在形态上出现受损症状，同时生长速率也受到明显的抑制。120h时，满江红鱼腥藻，水华鱼腥藻及固氮鱼腥藻的EC_(50)值分别为3.172， 3.654及3.377mg/L。

In this study, differences among tolerant capabilities of three species of nitrogen-fixation cyanobacteria (Anabaena azollae, Anabaena flos-aquae, Anabaena azotic) to two new sulfonylurea (Monosulfuron and Monosulfuron ester) were studied, which could be used to further explain the resistant mechanism to sulfonylurea herbicides and how these herbicides take effect.

本文以满江红鱼腥藻、固氮鱼腥藻及水华鱼腥藻为代表，利用环境毒理学的研究手段，通过研究3种固氮蓝藻对2种磺酰脲类除草剂---单嘧磺隆、单嘧磺酯的耐药性差异来揭示对磺酰脲类除草剂产生抗药性和耐药性的机理。
