The hands-on strategy is also applied to "field schools" for adults already working the land.

Again, in an electric field line splitting observed, the intensity of the line splitting varying with the intensity of the applied electric field.

结果也证明谱线在电场中也会分裂，而且其分裂程度,随电场强度变化而变化。

And, furthermore, that the intensity of the splitting was proportional to the intensity of the applied magnetic field.

并且谱线的分裂程度,和实验中所使用的磁场强度,是成比例的。
