Over an estimated 10,000 generations, the sticklebacks show structural differences that are greater than those seen between different genera of fish including variations in fins, changes in the number or size of their bony plates, variable jaw structure, and color differences.

估计已经有10000世代了，三刺鱼表现出的结构性差异大于我们看到的不同属的鱼类之间的差异，包括鳍的不同，骨板的数量或大小出现变化，可变的颌骨结构以及颜色的差异。

To study the animal model of experimental autoimmune myasthenia gravis induced with extract from electric organ of Narcine timilei in rats.

目的 从丁氏双鳍电鳐的电器官分离乙酰胆碱受体免疫大鼠，建立实验性自身免疫性重症肌无力动物模型。

Methods Lewis rats were immunized with the protein extracted from electric organ of Narcine timilei, the clinical manifestations were observed every day, and repetitive nerve stimulation,single fiber electromyography and the levels of acetylcholine receptor antibody were detected on the 49th days post immunization. The content of the protein extracted from electric organ of Narcine timile was 35.4 mg/mL, and the protein could respond with AChRAb from the serum of seropositive myasthenia gravis patient.

参照徐氏法从丁氏双鳍电鳐的电器官提取AChR蛋白，并采用Folin-酚试剂法及酶联免疫吸附法检测提取蛋白的含量及活性；以提取的蛋白主动免疫Lewis大鼠，每天观察其临床表现，并于免疫后7周进行低频重复电刺激、单纤维肌电图及血清中AChRAb水平的检测。

The flow field of crossing shock waves/turbulence boundary layer caused by 7°×11° double sharp fins was computed with Navier-Stokes equations and five turbulence models.

针对7°×11°双尖鳍外形的非对称交叉激波与湍流边界层相互作用，采用Navier-Stokes方程和5种湍流模型进行了计算。

McQuarrie's speeder bikes had spaceship-like fins and large, clear windscreens, but no real sense of where the power plant may be.

McQuarrie的飞行摩托有着太空船风格的鳍、夸张的外形和光亮的风挡玻璃，但却看不出发电机在哪里。

Also, young may have an orange longitudinal band running from the tip of the head to the caudal fin that fades as the fish matures.

年轻人可能还有一个橙色的纵向带尾的鳍消失，鱼成熟，从头的运行。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
