If the integrals of a one-form over all lines meeting a small open set vanish and the form is closed in this set, then the one-form is exact in the whole Euclidean space. We obtain a unique continuation result for the normal operator of the x-ray transform of one-forms, and this leads to one of our two proofs of the partial data result. Our proofs apply to compactly supported covector-valued distributions.

如果满足所有小开口集的所有线上的一个形式的积分消失,并且该形式在该集合中是闭合的,则该形式-形式在整个欧几里得空间中都是精确的。对于单一形式的X射线变换的法线算符,我们获得了唯一的连续结果,这导致我们获得了部分数据结果的两个证明之一。我们的证明适用于紧密支持的向量值分布。
