This article starts out from the characteristics of self-directeddistance learning, analyze the definition, characteristics and the core of compositions in the end...
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。

In addition, based on a semantic syntax-directed translation from pure patterns to distorted patterns, a distance measure including both semantics and syntax is proposed.
