本文介绍了在低气压下对双射流和三射流截面的测量结果。|不|\）\（ep \rightarrow eXY\）型衍射深度非弹性散射相互作用，其中系统X与低质量重子系统Y之间有一个大的快度间隙。用HERA的H1探测器获得的积分光度为18.0 pb ^{-1}的数据，测量了4.4 rmGeV强子能级的单微分截面和双微分截面.还研究了非射流能流。测量结果与轨迹截距接近1.2的因式分解衍射交换一致，并严格限制了主要的衍射胶子分布。从光子的部分子涨落的衍射散射来看，数据要求\（q\overline{q}g\）在\（q\overline{q}\）态上占优势。目前形式的柔和颜色中和模型不能同时再现微分截面的形状和归一化。基于2-胶子交换的模型能够再现低\（x_\mathbb{P}\）值下的截面形状。
A measurement is presented of dijet and 3-jet cross sections in low-\(|t|\) diffractive deep-inelastic scattering interactions of the type \(ep \rightarrow eXY\), where the system X is separated by a large rapidity gap from a low-mass baryonic system Y. Data taken with the H1 detector at HERA, corresponding to an integrated luminosity of 18.0 pb\(^{-1}\), are used to measure hadron level single and double differential cross sections for \(4 4 \rm GeV\). The energy flow not attributed to jets is also investigated. The measurements are consistent with a factorising diffractive exchange with trajectory intercept close to 1.2 and tightly constrain the dominating diffractive gluon distribution. Viewed in terms of the diffractive scattering of partonic fluctuations of the photon, the data require the dominance of \(q\overline{q}g\) over \(q\overline{q}\) states. Soft colour neutralisation models in their present form cannot simultaneously reproduce the shapes and the normalisations of the differential cross sections. Models based on 2-gluon exchange are able to reproduce the shapes of the cross sections at low \(x_\mathbb{P}\) values.
