It can pro vide a better voltage flat by increasement of numbers of helicalcoil sections a nd branch in parallel.
增加螺线管段数和导线并联分支数,可得到一个比较好的电压平台。

The two helical nanofibers have absolutely opposite helical senses, but have identical cycle number, coil diameter, coil length, coil pitch, fiber diameter, and fiber cross section.
