发现复眼中的晶锥、色素细胞、网膜细胞内含物及感杆,在这两个时刻的形态和结构有显著不同。
We found that there were various structural changes in cones, pigment cells, retinula cells, rhabdomeres at the two different times.
的细胞体、感杆和轴突较大,它与外周小网膜细胞R_(1~6)相同,其轴突终止在第一视神经节(薄板);
R_(7a) approximate many features of R_(1-6) cells, which have a larger, cell body, rhabdomere and axon, terminate in the first optic neuropil (lamina).
在果蝇这种较精密的复眼中,感杆小体彼此相隔,因此果蝇复眼的角分辨率显著提高,能够探测到较微小的运动物体。
In the more sophisticated eyes of flies, the rhabdomeres are separated, and as a result, fly eyes have significantly better angular resolution, and can detect smaller moving objects.
测验办法是,地感红灯闪耀时,用铁板放在线圈上,红灯长亮时取走铁板,闸杆主动落下则正常。
The test solution is to sense light shine, put the coil with the plate, a long red light when taking iron, brake rod fall automatically is normal.
本课题进行了以下设计与试验:(1)测定磁感喷油器的磁敏元件和挺杆之间的最佳间隙。
The experiments as follows are done:(1) Space of magnetism sense organ and needle valve is measured.
只需通过调节杆式探头夹具上的一个大调节把手来调整探头在储罐内的位置,就能很方便地设定其测感点。
Adjusting the sensor position in the tank easily sets the sensing point. This is accomplished with a large adjustment knob on the cane-probe clamp.
桥身和桥面充满工业感的冷峻钢材难免少了一丝亲切,为了与环境形成良好呼应,灯杆和扶手秉承就地取材的原则,选用道地的乡间材料——竹子,内部通体打穿并埋入照明线路。
The industrial steel structure of bridge make it unkind. So we chose the local material bamboo to make the light poles and handrails. Bamboos are pierced to put in lighting wires.
