Longer distance constraints are determined by site-directed spin labelling electron paramagnetic resonance, but current labelling strategies still constitute some limitation.
直接位点标记的旋转电子顺磁共振可以得到更长的距离约束数据，但是目前的标记策略仍然具有局限性。

A steady current is needed to maintain the color effect, thus the paramagnetic paint doesn't work when the vehicle is turned off and hence the vehicle switches back to a default white color.
