您要查找的是不是：
- The flatness of screen of the picture tube generates extension distortion of the picture( raster), or pincushion distortion. 显象管荧光屏的平面性，使图象（栅）生延伸性失真，即枕形失真。
- These are not derived from the neural crest, instead an outpouching of the neural tube generates the optic cup which, in turn, forms the retina. 不过视网膜上皮的黑色素细胞是其中的例外，它们并非由神经脊产生，而是在神经管外囊生成的视杯产生。
- The flatness of screen of the picture tube generates extension distortion of the picture( raster), or pincushion distortion . 显象管荧光屏的平面性，使图象（栅）生延伸性失真，即枕形失真。
- Applications such as measuring light with a photomultiplier tube generally require the use of a picoammeter due to the low current levels involved. 由于要测量的电流非常弱，所以用光电倍增管测量光的应用工作通常需要使用皮安计。
